The syllabus — what you’ll actually cover

Module	What it covers
Unit structure	The diploma is built from units across law, management, risk, health, environment and incident investigation — taken one at a time This unit is the baseline the later units assume — build it properly.
Each unit	A unit is a focused topic with a written assessment; open-book in most delivery modes; pass at 45% per unit The applied unit: the theory is simple until the assessment puts it in a workplace you must handle.
The management system	The OH&S management system in depth; the risk process; the legal register; the performance evaluation The practical core of the diploma — the unit that separates practitioners from paper candidates.
Specialisms	Health (ergonomics, occupational health, substance misuse); environment; fire; incident investigation; the units that make up the diploma Keep this unit warm while you take the next one; the diploma compounds.

The exam & assessment

A written assessment per unit, typically 800–1,000 words per question, open-book in most delivery modes. Pass at 45% per unit.

Duration & delivery

A multi-unit programme; each unit is a 2–4 week study block plus assessment. The full diploma is typically 6–12 months part-time through the official programme.

How to prepare — the tips that actually work

1. Take the units in an order that matches your role — the law and management units first if you are a manager
2. For every unit, write the 800-word answers by hand; word economy is the skill being tested
3. Keep a running case-law and standard note per unit; open-book still means you must know where things live
4. Pair each unit with real work: applying the unit to an actual site makes it stick

Where this takes your career

The OTHM Level 5 is the UK Level 5 credential for OH&S management. It is the standard route for HSE managers who need a formal Level 5 qualification without the full NEBOSH Diploma commitment.

What you’ll be able to do

• Complete a UK-regulated unit with a written assessment you can defend
• Build the OTHM diploma one unit at a time, at your own pace
• Hold a UK Level credential that employers and auditors recognise
• Move up the OTHM route with the units the next level expects
• Apply the unit to your real workplace — the assessment rewards applied answers

What the course actually looks like

The unit runs through the official programme as a focused study block plus the written assessment, at the pace that fits your work. You get the unit mapped section by section, the assessment format demonstrated, and the certificate on passing. Schedules and fees are published on the official website — one message gets you the written quote.

How employers see this qualification

OTHM is the route UK HSE professionals build a career on, and UK employers know it. Level 3 is the workforce baseline; Level 5 is the manager line on the CV; Level 6 and 7 are the senior and specialist lines. Because the diploma is unit-based, your CV shows progress unit by unit — which is exactly how UK employers like to see it.

Common mistakes candidates make

1. Treating the open-book assessment as a note-dumping exercise — the marking is on structure and the question
2. Taking the units in an order that does not match your role
3. Waiting until the deadline to start the written assessment; the word count takes real time
4. Skipping the applied examples; the OTHM markers want your workplace, not a textbook
