The NEBOSH closing interview is a short video call — typically 15 to 20 minutes — that you take after submitting your NG1 open book exam. A NEBOSH-appointed examiner asks you to explain a few of your answers in your own words. It’s an integrity check, not a re-test. If you wrote your own answers, you’ll have no trouble. The interview is mandatory; without it, your exam can’t be marked.
If you’ve just submitted your NEBOSH NG1 open book exam, the closing interview is the next thing you face. And for most learners, it’s the part of the assessment that causes the most worry — because it’s the part that’s hardest to picture in advance.
This guide covers what the closing interview actually is, what you’ll be asked, what NEBOSH is checking for, and how to prepare so you walk into the call confident. It draws on 41 years of taking KeyOstas learners through NEBOSH assessments — including every closing interview format NEBOSH has used since the open book exam was introduced.
The closing interview is a short video call between you and a NEBOSH-appointed examiner, scheduled after you submit your NG1 open book exam. It’s part of the assessment process — without completing it, your exam cannot be marked and your result cannot be released.
The interview exists for one reason: to confirm that the answers you submitted were written by you. NEBOSH introduced the closing interview alongside the open book format in 2020, partly to deter plagiarism and partly to deter the use of paid ghost-writers and (more recently) AI tools to generate exam answers.
The format:
NEBOSH typically schedules the closing interview within 4–8 weeks of your exam submission, though timing varies depending on the exam window and assessor availability. You’ll receive an invitation directly from NEBOSH with your scheduled time slot — not via your Learning Partner.
If the time you’re offered doesn’t work, you can request a reschedule, but availability is limited and changes can delay your final result. Best to take the original slot if you can.
The examiner has read your submitted answers before the call. They’ll have selected a small number of questions — usually two or three — that they want to discuss with you. The questions you’ll be asked fall into a few predictable patterns:
The most common opening. You’ll be asked to summarise your reasoning for a specific answer, in your own words. The examiner isn’t asking you to recite the answer verbatim — they’re checking that you understand what you wrote.
Drilling into a specific recommendation you made. The examiner wants to hear that you can defend the reasoning, not just that you can name a control.
A natural follow-up. They’re checking whether you genuinely thought through the scenario, or just picked the first idea that came to mind.
Occasionally — testing whether you can transfer NEBOSH principles to other contexts, which is something you can only do if you actually understood the material.
Light context-setting. Some examiners open with a few questions about your background to put you at ease before getting into the technical content.
The questions aren’t trying to trip you up. They aren’t trick questions. The examiner is professional, often a fellow safety practitioner, and the bar they’re setting is “this person clearly wrote and understood what they submitted.”
Three specific things:
If your written answers use complex terminology and structured argument, but you can’t explain that terminology or summarise the argument verbally, that’s a flag. The interview is the integrity check that automated plagiarism detection can’t quite do alone.
It’s possible to write a technically accurate answer by closely paraphrasing course material without fully understanding it. The interview tests whether you’ve genuinely absorbed the content — by asking you to explain it without your notes in front of you.
For a few candidates, the examiner will explore whether the reasoning shown in the written exam was a one-off — or whether you can apply the same kind of thinking to a different example. This isn’t a re-test; it’s a sample.
It’s worth being clear about a few things the closing interview doesn’t do:
“Failing” the closing interview is a specific outcome — it means NEBOSH has concluded the work you submitted wasn’t your own. This is uncommon, but the consequences are serious: NEBOSH may void your exam, prevent you from re-sitting for a defined period, or in serious cases bar you from NEBOSH assessments entirely.
If you wrote your own answers, this isn’t a risk you need to think about. The examiners are experienced — they can tell the difference between “candidate is nervous” and “candidate didn’t write this.”
If for any reason you’re unable to complete the interview at the scheduled time (illness, technical issue), contact NEBOSH directly to reschedule. Don’t simply not turn up — that creates more problems than it solves.
The biggest single mistake learners make is preparing for the closing interview as if it were a second exam. It isn’t. The preparation that actually helps is shorter, simpler, and starts the moment you submit your written answers.
Before you submit, save a copy of your written answers somewhere you can refer back to them. After submission, read them again — once a few days later, and again the day before the interview. Not to memorise anything, but to make sure you remember what you wrote and why.
For each answer you’re confident you wrote in your own words, practise explaining the reasoning verbally — talking to yourself, a partner, the dog. Out-loud rehearsal is different from reading silently. It tests whether you can articulate the ideas, not just recognise them on the page.
For each major recommendation you made in the exam, ask yourself two questions:
If you can answer those for each major recommendation in your written answers, you’re well prepared for the typical interview questions.
Practical:
Be in the call ready 5 minutes before your scheduled slot. Have a glass of water. Take three slow breaths. The examiners are generally punctual, and starting calm is much easier than starting flustered.
Most candidates get stuck not because they don’t know the answer, but because nerves cause a momentary blank. If it happens, ask the examiner to repeat the question while you compose yourself. Better still, take 5 seconds before answering — that pause feels much longer to you than to them.
Sometimes a candidate looks at their answer afresh, decides they were wrong, and tries to argue a different position in the interview. This is rarely a good move. Defend what you wrote, even if you’d write it differently now. Changing position mid-interview can read as not having understood the original answer.
You may technically be allowed to reference your written answers — but reading from them in the interview is a flag. The examiner can tell. Speak as if you’d just remembered the answer rather than reading it.
The examiner has a specific list of things they need to cover. Long detours into adjacent topics use up the call time without addressing what they need to confirm. Answer the question asked, then stop.
Internet drops, software won’t open, camera won’t work. Test everything the day before. Have NEBOSH’s support contact details to hand. If something fails mid-call, contact NEBOSH immediately rather than trying to reconnect indefinitely.
Once the interview is complete, your written exam moves into final marking. You don’t get a separate interview result. NEBOSH typically releases your final NG1 result around 50 working days after the exam window closes, regardless of when your specific interview took place.
You’ll receive your result by email, with the option to log in to the NEBOSH portal and see the breakdown.
Typically 15 to 20 minutes. Some run shorter, occasionally a few run a little longer if the examiner has more questions. It’s not a viva — it’s a focused integrity check.
No. The examiner picks two or three of your written answers to discuss in detail. They’ve chosen these in advance based on what they want to confirm, but you won’t be told which ones until the call.
You can keep your written answers nearby for reference. But reading from them defeats the point of the interview — and the examiner will notice. Speak from memory and understanding, not from a script.
Reconnect immediately. If you can’t reconnect within a few minutes, contact NEBOSH’s support team — they’ll typically reschedule the interview. Don’t simply abandon the call.
No. The interview is between you and the NEBOSH examiner only. Anyone else in the room — even silently in the background — could lead to the interview being invalidated. Make sure you’re alone in the space.
For UK candidates, the interview is in English. NEBOSH does offer interviews in other languages depending on assessor availability, but if you sat the exam in English, the interview will be in English.
The format is essentially the same, with minor differences in scheduling. If you’re sitting the IGC, expect a closing interview that follows the same pattern as the National General Certificate process described here.
The closing interview is part of why most candidates do better with a Learning Partner that supports them through the whole assessment process — not just the teaching. KeyOstas has been delivering NEBOSH qualifications since 1984, and we’ve taken thousands of learners through every closing interview format NEBOSH has used.
We’re a NEBOSH Gold Learning Partner (Centre 009) — the highest tier NEBOSH offers. Our first-time pass rate runs at 85% or above, well over the national average. Our tutors are practising health and safety professionals, and our post-exam support includes interview preparation as standard.
