The exam & assessment

Duration & delivery

A multi-unit programme; each unit is a focused 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. The Level 6 standard is synthesis and judgement — practise the strategic question type
2. Keep a running note of board-level cases and assurance frameworks; the exam draws on them
3. Pair each unit with a real strategic decision from your organisation
4. Write the answers at board-brief length: concise, decisive, defensible

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
