If your organisation runs on screens, Irish law does not ask you to hand out a self-assessment form and file it. It asks you to have a named, trained, competent person analyse each workstation, record what they found, and act on it. This guide explains exactly what that duty says, who in your organisation should hold it, and which DSE training course actually matches the job in front of you.
Most people arrive at this topic for one of three reasons. A safety audit flagged a gap. A staff member reported wrist, neck or back pain and nobody was qualified to assess the desk. Or a physiotherapist, occupational therapist or H&S consultant spotted that workstation assessment is a service they could deliver themselves rather than refer out.
All three are solved by the same qualification, but by different levels of it. Below you'll find the legal position in plain English, the numbers behind the risk, a breakdown of which DSE training course suits which type of person or organisation, and an interactive tool to match you to a track in about twenty seconds.
What Irish law actually requires — Chapter 5 of Part 2
Display screen equipment is governed in Ireland by the Safety, Health and Welfare at Work (General Application) Regulations 2007 (S.I. No. 299 of 2007), Chapter 5 of Part 2, Regulations 70 to 73, plus Schedule 4. That chapter transposes the EU Display Screen Equipment Directive 90/270/EEC into Irish law, and it sits on top of the general duties in the Safety, Health and Welfare at Work Act 2005.
Three points from the HSA's own guidance are worth stating bluntly, because they are the ones organisations most often get wrong:
- A self-assessment form on its own does not discharge the duty. The HSA guidance is explicit that it is not enough to let employees assess their own workstations through a software package — the employer must be actively engaged in completing a physical risk assessment of the individual workstation.
- The analysis must be carried out by a competent person. Competence is defined by sufficient training, experience and knowledge appropriate to the work being undertaken — in this case, analysing a workstation.
- It must be written down and shared. The results of the analysis have to be recorded, given to the employee, and any changes made to the workstation recorded too.
Open any of the duties below to see what the regulation requires and what it means in practice.
Reg 70What counts as DSE, a user, and a workstation
Display screen equipment means any alphanumeric or graphic display screen, whatever the display technology. A workstation is deliberately broad: the screen, keyboard or input device, software, the work chair and desk or work surface, accessories and peripherals, and the immediate work environment.
An employee under this chapter is someone who habitually uses DSE as a significant part of normal work. The HSA's practical test is whether the person has no choice but to use the screen to do their job, normally uses it for continuous periods of more than an hour, and uses it daily.
One detail that surprises people: the HSA guidance notes that a laptop on its own does not meet the Schedule 4 requirement for a keyboard that is tiltable and separate from the screen. Laptop setups still need a risk assessment, and the practical fix is a separate monitor and keyboard so the workstation can be properly assessed.
Reg 71Where the chapter does not apply
The chapter excludes drivers' and control cabs, computer systems on board transport, systems mainly intended for public use, portable DSE not in prolonged use at a workstation, calculators and cash registers and small measurement displays, and traditional "typewriter with window" designs.
Important caveat: an exclusion here does not switch off the employer's general duty of care under the 2005 Act. It only means the specific DSE rules don't bite.
Reg 72(1)(b)Analyse the workstation and remedy the risks
The employer must analyse the workstation to evaluate the safety and health conditions it creates, with particular regard to risks to eyesight, physical problems and mental stress — then take measures to remedy what is found, taking account of the minimum requirements in Schedule 4 and any combined effects.
The HSA guidance sets out what a documented assessment should contain:
- A brief overview of the tasks carried out at the workstation
- Evidence that every aspect of Schedule 4 was considered
- Details of the issues that need follow-up
- An action plan naming who is responsible, what will be done, and by when
This is the single duty that makes internal assessor training worth doing. It is a recurring, documented, per-person task — not a one-off project.
Reg 72(1)(c)Breaks and changes of activity
Work must be planned so that daily screen work is periodically interrupted by breaks or changes of activity that reduce the load at the screen. The regulations set no fixed frequency, but the HSA guidance states that no single continuous period at a screen should generally exceed one hour.
The guidance also favours short frequent breaks over occasional long ones, taken before fatigue sets in, and taken away from the screen.
Reg 72(1)(d)–(e)Information and training for users
Employers must inform employees about the measures applied to their workstation, and must provide training in the use of the workstation before screen work begins, and again whenever the organisation of the workstation is substantially modified.
Note the distinction this creates. User awareness training is what every screen worker needs. Assessor training is what the competent person needs in order to carry out and sign off the Regulation 72(1)(b) analysis. They are different qualifications for different people.
Reg 72(1)(f)Reassessment triggers
A further analysis is required where an employee transfers to a new workstation, or where significant new work equipment, a change of equipment or new technology is introduced at an individual's workstation.
In a hot-desking or hybrid organisation this trigger fires constantly, which is precisely why organisations with distributed teams tend to need more than one trained assessor.
Reg 73Eye and eyesight tests
Employers must make employees aware of, and make available, an appropriate eye and eyesight test carried out by a competent person: before starting screen work, at regular intervals afterwards, and if the employee experiences visual difficulties that may be due to screen work.
Where the test shows special corrective appliances are needed specifically for screen work and normal glasses won't do, the employer covers the cost of basic frames and lenses. Where an employee's existing glasses are adequate for screen work, the employer isn't liable for a routine lens change.
Schedule 4The minimum requirements you are assessing against
Schedule 4 is the checklist the analysis has to be measured against. It covers equipment (screen, keyboard, desk or work surface, chair), environment (space, lighting, reflections and glare, radiation, noise, heat, humidity) and the employee/computer interface — including that software must be suitable for the task and that no quantitative or qualitative checking facility may be used without employees' knowledge.
The HSA commentary attaches usable numbers to several of these, which is what a trained assessor works from:
- Minimum floor space per person in an office: 4.65 square metres, including desk and chair
- General lighting level: 300 to 500 lux, with local lighting for document reading
- Elbow angle between forearm and upper arm when seated at the keyboard: roughly 70° to 90°
- Thermal comfort for sedentary work: 18–24°C with relative humidity between 30% and 70%
- Chair: stable, height-adjustable seat, backrest adjustable in height and tilt, footrest available to anyone who needs one
A good workstation assessor course is essentially training in applying this schedule to a real human being rather than reciting it.
What non-compliance costs
Breaches of health and safety law in Ireland are criminal offences. Under the Safety, Health and Welfare at Work Act 2005, summary convictions in the District Court carry fines in the low thousands of euro, while conviction on indictment in the Circuit Court carries a maximum fine of €3 million and/or up to two years' imprisonment. The HSA may also publish the names of those penalised. See the HSA's summary of the 2005 Act.
In practice, the more common exposure for office employers isn't prosecution — it's a personal injury claim for a musculoskeletal injury where the employer has no documented, competently performed workstation assessment to point to.
VDU or DSE — does the wording matter?
VDU (Visual Display Unit) is the older term; DSE (Display Screen Equipment) is the wording used in the 2007 Regulations and in current HSA guidance. They describe the same equipment and the same duty. The HSA's own FAQ document still refers to DSE as VDU, which is why both terms persist in Irish policy documents, insurance schedules and job descriptions.
So a VDU training course and a DSE training course are the same course, and a certificate in either name satisfies the same requirement. If your internal safety statement still says "VDU", there's no need to rewrite it — just make sure whoever holds the assessor role knows the modern terminology when dealing with an inspector.
Who should hold the assessor qualification?
This is where most organisations and individuals get stuck, because "who needs DSE training" has a different answer depending on why you're asking. Pick the description closest to you.
Physiotherapists and occupational therapists: adding a billable service
If you already treat neck pain, thoracic stiffness, lateral epicondylitis and wrist complaints in private practice, you are treating the downstream effect of workstations you never get to see. Assessor certification lets you go upstream — and lets you sell the visit rather than refer it away.
Clinically, you are not starting from zero. You already have the anatomy, the postural analysis, the special tests and the patient-handling skills. What the course adds is the part clinicians typically haven't been taught: the statutory framework, what Schedule 4 requires component by component, how to write an assessment that stands up as a legal record, and how to specify equipment defensibly rather than by brand preference.
Commercially, it opens a few doors at once. Corporate clients buy assessments in blocks rather than one at a time. Employers are obliged to act on the findings, so recommendations convert. And a clinician who can do the assessment, prescribe the equipment and handle the return-to-work case is a much easier sell to an HR department than three separate suppliers.
Health & safety officers: closing the gap NEBOSH and IOSH leave
General H&S qualifications give you the management system — risk assessment methodology, safety statements, consultation, incident investigation. What they don't give you is enough depth on workstation ergonomics to make a defensible judgement about a specific person's desk, or to tell the difference between an employee who needs their chair adjusted and one who needs a specialist chair and a phased return.
That gap matters because DSE is the highest-volume assessment type in most office-based organisations. Every new starter, every desk move, every equipment change under Regulation 72(1)(f) is another assessment. Outsourcing all of them is expensive; doing them without training is the exposure.
Assessor certification also changes your position in a claim. A documented assessment carried out by a named, certified competent person, with an action plan and completion dates, is a materially different piece of evidence from a returned checklist.
HR and office managers: the person who inherits the problem
In a lot of Irish SMEs, DSE compliance lands on HR or office management by default — usually the moment someone requests a special chair, reports discomfort, or asks for equipment for their home desk. Without training, the realistic options are to approve everything, approve nothing, or call an external consultant every time.
Training makes the middle path possible. You can separate a genuine ergonomic need from a preference, document the decision either way, know when a case is beyond your competence and needs escalation to a clinical assessment, and handle pregnancy-related and medical adjustments correctly rather than nervously.
It also gives you the induction piece. Regulation 72(1)(e) requires training for users before they begin screen work — a trained internal assessor can deliver that induction content in-house instead of buying an e-learning licence per head.
Small and mid-sized employers: in-house capability for a one-off cost
For an employer with somewhere between 15 and 150 screen users, the arithmetic is straightforward. Every desk needs an assessment. Every new hire needs one. Every desk move and equipment change triggers a fresh one under Regulation 72(1)(f). Buying that externally, per person, indefinitely, costs more than training one or two of your own people and keeping the capability in the building.
Having an internal competent person also collapses your response time. The gap between "I've had a sore shoulder for three weeks" and a completed, actioned assessment is usually where a minor complaint becomes an absence. Internally, that gap is days. Externally, it's however long the next scheduled visit is away.
The honest caveat: internal capability has a ceiling. Complex medical cases, pregnancy assessments, post-injury return-to-work and Workplace Needs Assessments are worth keeping external, and a well-trained internal assessor is exactly the person who can tell which is which.
Multi-site and enterprise employers: consistency is the real problem
At scale, the compliance risk isn't usually that assessments aren't happening — it's that they're happening five different ways. Different sites use different forms, apply different thresholds for equipment spend, and keep records in different places. When a claim or an inspection arrives, the inconsistency is the finding.
Group training solves this by putting every assessor through the same methodology at the same time, using your actual office environment, your actual equipment standards and your actual escalation process as the teaching material. You come out with a common standard rather than a group of individually certified people.
The second half of the problem is the audit trail. Once you have a dozen trained assessors producing assessments across several sites, spreadsheets stop working. That's the point at which DSE management software earns its place — central records, assessment status per employee, follow-up actions and reporting for the board.
Occupational health nurses and H&S consultants
If you already run pre-placement screening, health surveillance and return-to-work reviews, DSE assessment is the missing practical intervention at the end of that pathway. You identify the problem; assessor certification lets you fix the environment that caused it rather than writing a recommendation someone else interprets.
For independent consultants, it's straightforwardly an additional service line with recurring demand — assessor certification should be refreshed every three years, workforces turn over, and hybrid arrangements keep changing what needs assessing.
The four training tracks, compared
KOS runs a structured pathway rather than a single generic course, because a physiotherapist entering the field and an office manager who has never heard of Schedule 4 do not need the same day.
| Level 1 — Essential | Level 2 — Advanced & Refresher | Compliant Remote Assessment | Group / On-site | |
|---|---|---|---|---|
| Built for | Anyone new to DSE: safety officers, HR, office managers, facilities | Existing assessors, H&S managers, physiotherapists, OTs, occupational health nurses | Anyone assessing hybrid or home-based workers over video | Teams needing a single consistent standard across a site or several sites |
| Prerequisite | None | Level 1, or an existing clinical / H&S qualification | Level 1 | Matches the track being delivered |
| Core content | Ergonomics and anthropometrics; Irish and European legislation; hazards and risks; workstation and environmental factors; hot-desking, sit-stand desks, home working, laptops and tablets; practical assessment technique | Review of Irish regulations; anatomy and physiology at the workstation; how common office injuries arise and how to reduce them; working postures, flexibility and individual cases; practical review of ergonomic equipment — when and why; return-to-work scenarios | Information gathering at distance; technology and platform choice; communication technique; guiding a user through their own setup; documenting a remote assessment to the same standard as an on-site one | Any of the three tracks, customised to your office environment, equipment standards and escalation process |

Match yourself to a course
Three questions. The recommendation appears underneath.
Which DSE training course do I need?
1. Which describes you best?
2. How much DSE assessment experience is already in place?
3. Where do the people you'd be assessing actually work?
Where to find dates and book
Live online sessions run via Microsoft Teams and are capped to keep them interactive, so places on the foundation course in particular tend to go early. The training course page carries the live calendar with current availability across every track — new dates are added there as they're released.
Level 2 — Advanced & Refresher
- Live online, one full day, 9am–5pm
- Level 1 or an existing clinical / H&S qualification
Group & on-site
- Scheduled to suit your team
- On-site anywhere in Ireland, or dedicated remote
- Available for all three tracks
The hybrid problem, and why it needs its own module
CSO Labour Force Survey data for Q2 2026 records 990,600 people in Ireland working from home usually or sometimes — 34.9% of everyone in employment, against a pre-pandemic baseline of 20.3% in 2019. The composition has shifted (fully remote down, hybrid up) but the headline share has been broadly stable for several years. Hybrid working is a permanent feature of the Irish labour market, not a transitional state.
The legal position doesn't soften at the front door. An employer's duty of care extends to employees working from home, and the DSE duties apply to habitual screen users wherever the screen is — see Citizens Information on working at home and the HSA's remote working guidance. Under the Work Life Balance and Miscellaneous Provisions Act 2023 employees can request remote working and employers must consider it, which means more of these arrangements are formalised and documented than used to be the case.
That creates a practical problem: you cannot walk around a home office. You can't put your hand on the backrest, watch someone reach for the mouse, or measure the gap between the seat pan and the back of the knee. A video call assessment carried out without technique tends to produce a photo of a desk and a note saying "looks fine" — which is precisely the kind of record that fails when tested.
The remote assessment module exists to fix that: structured information gathering before the call, choosing the right technology and camera angles, verbal guidance that gets the user to adjust their own setup accurately, and documentation that meets the same standard as an on-site assessment. If you want the user-facing version of this for your staff, our guide to setting up an ergonomic workspace at home is a useful companion piece to circulate after an assessment.
Certification, CPD and the three-year cycle
On passing the end-of-day exam you receive a KOS Training Academy certificate, CPD approved and valid for three years. Two things follow from that.
First, the three-year validity isn't administrative. Legislation, guidance and equipment all move, and an assessor working from a 2019 mental model of what a workstation looks like will miss things — sit-stand usage patterns, dual-monitor setups, laptop-first working, home office constraints. Level 2 functions as both the advanced course and the refresher, which is why experienced assessors and first-time clinicians end up in the same room.
Second, CPD points matter differently depending on who you are. For a physiotherapist or OT it feeds a professional portfolio you're already maintaining. For an H&S professional it's evidence of role-specific competence that a general qualification doesn't supply. For an employer it's the documentary proof that the person named as your competent person actually is one.
Courses are delivered by KOS's clinical team — BSc and MSc qualified physiotherapists and certified occupational therapists with corporate ergonomics experience behind them, drawing on more than 20,000 completed workstation assessments. That matters most at Level 2, where the questions stop being "does this chair comply" and start being "this person has a fused L4/L5, what do we actually do".
Before you book: a five-minute self-audit
Run these questions against your own organisation. Any "no" is a gap that assessor training closes.
- Can you name the person in your organisation who is the competent person for DSE, and produce their certificate?
- For a randomly chosen employee, can you produce a written workstation analysis that references Schedule 4, names the actions taken, and shows who did what by when?
- Was that analysis shared with the employee?
- Do your home and hybrid workers have assessments carried out to the same standard as your office staff?
- When someone moves desk or gets new equipment, does a reassessment actually get triggered?
- Have your screen users been told, in writing, that they're entitled to an eye and eyesight test?
- Do you have a documented route for cases beyond your internal competence — pregnancy, existing injury, post-surgical return to work?
If questions 1 and 2 are a "no", start at Level 1. If they're a "yes" but 4 is a "no", the remote module is your gap. If 7 is a "no", you need Level 2 depth internally, an external clinical assessment route, or both.

What Irish law actually requires — Chapter 5 of Part 2
Display screen equipment is governed in Ireland by the Safety, Health and Welfare at Work (General Application) Regulations 2007 (S.I. No. 299 of 2007), Chapter 5 of Part 2, Regulations 70 to 73, plus Schedule 4. That chapter transposes the EU Display Screen Equipment Directive 90/270/EEC into Irish law, and it sits on top of the general duties in the Safety, Health and Welfare at Work Act 2005.
Three points from the HSA's own guidance are worth stating bluntly, because they are the ones organisations most often get wrong:
- A self-assessment form on its own does not discharge the duty. The HSA guidance is explicit that it is not enough to let employees assess their own workstations through a software package — the employer must be actively engaged in completing a physical risk assessment of the individual workstation.
- The analysis must be carried out by a competent person. Competence is defined by sufficient training, experience and knowledge appropriate to the work being undertaken — in this case, analysing a workstation.
- It must be written down and shared. The results of the analysis have to be recorded, given to the employee, and any changes made to the workstation recorded too.
Open any of the duties below to see what the regulation requires and what it means in practice.
Reg 70What counts as DSE, a user, and a workstation
Display screen equipment means any alphanumeric or graphic display screen, whatever the display technology. A workstation is deliberately broad: the screen, keyboard or input device, software, the work chair and desk or work surface, accessories and peripherals, and the immediate work environment.
An employee under this chapter is someone who habitually uses DSE as a significant part of normal work. The HSA's practical test is whether the person has no choice but to use the screen to do their job, normally uses it for continuous periods of more than an hour, and uses it daily.
One detail that surprises people: the HSA guidance notes that a laptop on its own does not meet the Schedule 4 requirement for a keyboard that is tiltable and separate from the screen. Laptop setups still need a risk assessment, and the practical fix is a separate monitor and keyboard so the workstation can be properly assessed.
Reg 71Where the chapter does not apply
The chapter excludes drivers' and control cabs, computer systems on board transport, systems mainly intended for public use, portable DSE not in prolonged use at a workstation, calculators and cash registers and small measurement displays, and traditional "typewriter with window" designs.
Important caveat: an exclusion here does not switch off the employer's general duty of care under the 2005 Act. It only means the specific DSE rules don't bite.
Reg 72(1)(b)Analyse the workstation and remedy the risks
The employer must analyse the workstation to evaluate the safety and health conditions it creates, with particular regard to risks to eyesight, physical problems and mental stress — then take measures to remedy what is found, taking account of the minimum requirements in Schedule 4 and any combined effects.
The HSA guidance sets out what a documented assessment should contain:
- A brief overview of the tasks carried out at the workstation
- Evidence that every aspect of Schedule 4 was considered
- Details of the issues that need follow-up
- An action plan naming who is responsible, what will be done, and by when
This is the single duty that makes internal assessor training worth doing. It is a recurring, documented, per-person task — not a one-off project.
Reg 72(1)(c)Breaks and changes of activity
Work must be planned so that daily screen work is periodically interrupted by breaks or changes of activity that reduce the load at the screen. The regulations set no fixed frequency, but the HSA guidance states that no single continuous period at a screen should generally exceed one hour.
The guidance also favours short frequent breaks over occasional long ones, taken before fatigue sets in, and taken away from the screen.
Reg 72(1)(d)–(e)Information and training for users
Employers must inform employees about the measures applied to their workstation, and must provide training in the use of the workstation before screen work begins, and again whenever the organisation of the workstation is substantially modified.
Note the distinction this creates. User awareness training is what every screen worker needs. Assessor training is what the competent person needs in order to carry out and sign off the Regulation 72(1)(b) analysis. They are different qualifications for different people.
Reg 72(1)(f)Reassessment triggers
A further analysis is required where an employee transfers to a new workstation, or where significant new work equipment, a change of equipment or new technology is introduced at an individual's workstation.
In a hot-desking or hybrid organisation this trigger fires constantly, which is precisely why organisations with distributed teams tend to need more than one trained assessor.
Reg 73Eye and eyesight tests
Employers must make employees aware of, and make available, an appropriate eye and eyesight test carried out by a competent person: before starting screen work, at regular intervals afterwards, and if the employee experiences visual difficulties that may be due to screen work.
Where the test shows special corrective appliances are needed specifically for screen work and normal glasses won't do, the employer covers the cost of basic frames and lenses. Where an employee's existing glasses are adequate for screen work, the employer isn't liable for a routine lens change.
Schedule 4The minimum requirements you are assessing against
Schedule 4 is the checklist the analysis has to be measured against. It covers equipment (screen, keyboard, desk or work surface, chair), environment (space, lighting, reflections and glare, radiation, noise, heat, humidity) and the employee/computer interface — including that software must be suitable for the task and that no quantitative or qualitative checking facility may be used without employees' knowledge.
The HSA commentary attaches usable numbers to several of these, which is what a trained assessor works from:
- Minimum floor space per person in an office: 4.65 square metres, including desk and chair
- General lighting level: 300 to 500 lux, with local lighting for document reading
- Elbow angle between forearm and upper arm when seated at the keyboard: roughly 70° to 90°
- Thermal comfort for sedentary work: 18–24°C with relative humidity between 30% and 70%
- Chair: stable, height-adjustable seat, backrest adjustable in height and tilt, footrest available to anyone who needs one
A good workstation assessor course is essentially training in applying this schedule to a real human being rather than reciting it.
What non-compliance costs
Breaches of health and safety law in Ireland are criminal offences. Under the Safety, Health and Welfare at Work Act 2005, summary convictions in the District Court carry fines in the low thousands of euro, while conviction on indictment in the Circuit Court carries a maximum fine of €3 million and/or up to two years' imprisonment. The HSA may also publish the names of those penalised. See the HSA's summary of the 2005 Act.
In practice, the more common exposure for office employers isn't prosecution — it's a personal injury claim for a musculoskeletal injury where the employer has no documented, competently performed workstation assessment to point to.
VDU or DSE — does the wording matter?
VDU (Visual Display Unit) is the older term; DSE (Display Screen Equipment) is the wording used in the 2007 Regulations and in current HSA guidance. They describe the same equipment and the same duty. The HSA's own FAQ document still refers to DSE as VDU, which is why both terms persist in Irish policy documents, insurance schedules and job descriptions.
So a VDU training course and a DSE training course are the same course, and a certificate in either name satisfies the same requirement. If your internal safety statement still says "VDU", there's no need to rewrite it — just make sure whoever holds the assessor role knows the modern terminology when dealing with an inspector.
Who should hold the assessor qualification?
This is where most organisations and individuals get stuck, because "who needs DSE training" has a different answer depending on why you're asking. Pick the description closest to you.

You can separate a genuine ergonomic need from a preference, document the decision either way, know when a case is beyond your competence and needs escalation to a clinical assessment, and handle pregnancy-related and medical adjustments correctly rather than nervously.

Buying that externally, per person, indefinitely, costs more than training one or two of your own people and keeping the capability in the building.

The gap between "I've had a sore shoulder for three weeks" and a completed, actioned assessment is usually where a minor complaint becomes an absence. Internally, that gap is days. Externally, it's however long the next scheduled visit is away.
The honest caveat: internal capability has a ceiling. Complex medical cases, pregnancy assessments, post-injury return-to-work and Workplace Needs Assessments are worth keeping external, and a well-trained internal assessor is exactly the person who can tell which is which.
Multi-site and enterprise employers: consistency is the real problem
At scale, the compliance risk isn't usually that assessments aren't happening — it's that they're happening five different ways. Different sites use different forms, apply different thresholds for equipment spend, and keep records in different places. When a claim or an inspection arrives, the inconsistency is the finding.
Group training solves this by putting every assessor through the same methodology at the same time, using your actual office environment, your actual equipment standards and your actual escalation process as the teaching material. You come out with a common standard rather than a group of individually certified people.
The second half of the problem is the audit trail. Once you have a dozen trained assessors producing assessments across several sites, spreadsheets stop working. That's the point at which DSE management software earns its place — central records, assessment status per employee, follow-up actions and reporting for the board.
Occupational health nurses and H&S consultants
If you already run pre-placement screening, health surveillance and return-to-work reviews, DSE assessment is the missing practical intervention at the end of that pathway. You identify the problem; assessor certification lets you fix the environment that caused it rather than writing a recommendation someone else interprets.
For independent consultants, it's straightforwardly an additional service line with recurring demand — assessor certification should be refreshed every three years, workforces turn over, and hybrid arrangements keep changing what needs assessing.
The four training tracks, compared
KOS runs a structured pathway rather than a single generic course, because a physiotherapist entering the field and an office manager who has never heard of Schedule 4 do not need the same day.
| Level 1 — Essential | Level 2 — Advanced & Refresher | Compliant Remote Assessment | Group / On-site | |
|---|---|---|---|---|
| Built for | Anyone new to DSE: safety officers, HR, office managers, facilities | Existing assessors, H&S managers, physiotherapists, OTs, occupational health nurses | Anyone assessing hybrid or home-based workers over video | Teams needing a single consistent standard across a site or several sites |
| Prerequisite | None | Level 1, or an existing clinical / H&S qualification | Level 1 | Matches the track being delivered |
| Core content | Ergonomics and anthropometrics; Irish and European legislation; hazards and risks; workstation and environmental factors; hot-desking, sit-stand desks, home working, laptops and tablets; practical assessment technique | Review of Irish regulations; anatomy and physiology at the workstation; how common office injuries arise and how to reduce them; working postures, flexibility and individual cases; practical review of ergonomic equipment — when and why; return-to-work scenarios | Information gathering at distance; technology and platform choice; communication technique; guiding a user through their own setup; documenting a remote assessment to the same standard as an on-site one | Any of the three tracks, customised to your office environment, equipment standards and escalation process |
| Format | One full day, 9am–5pm, live interactive online via Microsoft Teams | One full day, 9am–5pm, live interactive online via Microsoft Teams | Half day, 9am–1pm, live online | On-site at your premises anywhere in Ireland, or a dedicated remote session |
| Assessment | Problem-based learning, practical exercises, end-of-day exam | Problem-based learning, complex case work, end-of-day exam | Practical remote assessment exercises | As per track |
| Certification | KOS Training Academy certificate, CPD approved, valid for three years, recognised as evidence of competent-person status. Full training pack and reusable assessment template included. | |||
| Book | Level 1 dates | Level 2 dates | Remote course dates | Enquire for group rates |

Match yourself to a course
Three questions. The recommendation appears underneath.
Which DSE training course do I need?
1. Which describes you best?
2. How much DSE assessment experience is already in place?
3. Where do the people you'd be assessing actually work?
Where to find dates and book
Live online sessions run via Microsoft Teams and are capped to keep them interactive, so places on the foundation course in particular tend to go early. The training course page carries the live calendar with current availability across every track — new dates are added there as they're released.
Level 2 — Advanced & Refresher
- Live online, one full day, 9am–5pm
- Level 1 or an existing clinical / H&S qualification
Group & on-site
- Scheduled to suit your team
- On-site anywhere in Ireland, or dedicated remote
- Available for all three tracks
The hybrid problem, and why it needs its own module
CSO Labour Force Survey data for Q2 2026 records 990,600 people in Ireland working from home usually or sometimes — 34.9% of everyone in employment, against a pre-pandemic baseline of 20.3% in 2019. The composition has shifted (fully remote down, hybrid up) but the headline share has been broadly stable for several years. Hybrid working is a permanent feature of the Irish labour market, not a transitional state.
The legal position doesn't soften at the front door. An employer's duty of care extends to employees working from home, and the DSE duties apply to habitual screen users wherever the screen is — see Citizens Information on working at home and the HSA's remote working guidance. Under the Work Life Balance and Miscellaneous Provisions Act 2023 employees can request remote working and employers must consider it, which means more of these arrangements are formalised and documented than used to be the case.
That creates a practical problem: you cannot walk around a home office. You can't put your hand on the backrest, watch someone reach for the mouse, or measure the gap between the seat pan and the back of the knee. A video call assessment carried out without technique tends to produce a photo of a desk and a note saying "looks fine" — which is precisely the kind of record that fails when tested.
The remote assessment module exists to fix that: structured information gathering before the call, choosing the right technology and camera angles, verbal guidance that gets the user to adjust their own setup accurately, and documentation that meets the same standard as an on-site assessment. If you want the user-facing version of this for your staff, our guide to setting up an ergonomic workspace at home is a useful companion piece to circulate after an assessment.
Certification, CPD and the three-year cycle
On passing the end-of-day exam you receive a KOS Training Academy certificate, CPD approved and valid for three years. Two things follow from that.
First, the three-year validity isn't administrative. Legislation, guidance and equipment all move, and an assessor working from a 2019 mental model of what a workstation looks like will miss things — sit-stand usage patterns, dual-monitor setups, laptop-first working, home office constraints. Level 2 functions as both the advanced course and the refresher, which is why experienced assessors and first-time clinicians end up in the same room.
Second, CPD points matter differently depending on who you are. For a physiotherapist or OT it feeds a professional portfolio you're already maintaining. For an H&S professional it's evidence of role-specific competence that a general qualification doesn't supply. For an employer it's the documentary proof that the person named as your competent person actually is one.
Courses are delivered by KOS's clinical team — BSc and MSc qualified physiotherapists and certified occupational therapists with corporate ergonomics experience behind them, drawing on more than 20,000 completed workstation assessments. That matters most at Level 2, where the questions stop being "does this chair comply" and start being "this person has a fused L4/L5, what do we actually do".
Before you book: a five-minute self-audit
Run these questions against your own organisation. Any "no" is a gap that assessor training closes.
- Can you name the person in your organisation who is the competent person for DSE, and produce their certificate?
- For a randomly chosen employee, can you produce a written workstation analysis that references Schedule 4, names the actions taken, and shows who did what by when?
- Was that analysis shared with the employee?
- Do your home and hybrid workers have assessments carried out to the same standard as your office staff?
- When someone moves desk or gets new equipment, does a reassessment actually get triggered?
- Have your screen users been told, in writing, that they're entitled to an eye and eyesight test?
- Do you have a documented route for cases beyond your internal competence — pregnancy, existing injury, post-surgical return to work?
If questions 1 and 2 are a "no", start at Level 1. If they're a "yes" but 4 is a "no", the remote module is your gap. If 7 is a "no", you need Level 2 depth internally, an external clinical assessment route, or both.
