Exam Invigilator Pay: £12.85–£16.85/hr (2026/27)

Invigilation is the most visible job in a school that almost nobody understands the economics of. For three weeks every June a group of adults — some retired teachers, some parents, some support staff picking up extra hours, some agency staff who arrived that morning — stand at the front of a sports hall for two and a half hours doing what looks, from a candidate's desk, like nothing at all. The job is neither as simple nor as well paid as it appears, and it is routinely confused with examining, which is a completely different role with a completely different pay structure.

This page sets out what invigilators are actually paid, using dated 2026 adverts rather than salary-aggregator averages; anchors those figures against the one published pay structure that genuinely governs most of them, the NJC spine; and then explains what the job involves according to the document that actually defines it, which is published by JCQ and is free for anyone to read. It finishes with the exams officer role, which is the properly graded career post sitting immediately above invigilation and which pays two to three times as much.

Invigilating is not examining

Start here, because the two get conflated constantly — including by people advising teachers on how to earn extra money — and the differences run all the way down.

The practical consequence is that they suit different people. Invigilation is open to anyone the head of centre judges suitable, needs no subject knowledge, pays a modest but reliable hourly rate with employment rights attached, and requires you to be physically present in a building at fixed times. Examining needs subject expertise, pays a lump sum for a defined output, can be done at eleven at night in your own kitchen, and carries a much stranger tax position. Our guide to exam marking pay covers the other side in full.

What the 2026 adverts actually say

Salary aggregator sites will tell you an exam invigilator earns "around £12 to £14 an hour", which is true but useless, because it conceals both the spread and the holiday pay mechanics that materially change the real figure. Here instead are actual advertised rates from schools and colleges in 2026, each with its own grading language.

Three patterns are worth pulling out of that table, because each one tells you something you cannot get from an average.

• The base rates cluster tightly. Six of the eight sit between £12.85 and £13.75, a spread of ninety pence. This is not a market where shopping around gains you much within the state sector — sixth form colleges and agency work are where the higher numbers are.
• The grade language is wildly inconsistent. "Grade B4", "NJC Grade 2 SP4", "Bucks Pay Range 2 Point 11", and plain "casual contract" all describe roughly the same money. Local grading systems are layered on top of the national spine and obscure it, which is exactly why the next section is necessary.
• Holiday pay is sometimes quoted inside the rate and sometimes outside it. Farnborough's £14.38 looks better than Misbourne's £13.75 until you notice Farnborough's figure already includes £1.55 of holiday pay, so its base rate is £12.83 — the lowest in the table. Always ask which you are being quoted.

The NJC pay spine is the real anchor

School support staff in England, Wales and Northern Ireland are overwhelmingly paid on the National Joint Council for Local Government Services pay spine — the Green Book spine — either directly in maintained schools or by adoption in most academy trusts. Invigilators are support staff. Even where the advert calls the rate something local, the number underneath it is nearly always a spine point.

The relevant agreement for the current year was circulated on 24 August 2026 and applies a 3.3% increase to spine points 3 to 43, implemented from 1 April 2026 — backdated, with the agreement recommending that employers pay monies due to employees who have since left, on request. Two spine points have been removed from the bottom of the spine in recent years: SCP 1 was deleted with effect from 1 April 2023, and SCP 2 was deleted with effect from 1 April 2026, which means the spine now starts at SCP 3.

Hourly rates on the NJC spine are calculated by dividing the annual salary by 52.143 weeks and then by 37 hours, which is why they carry odd pence values.

That observation has a practical edge. An advert quoting £12.85 or £13.05 in the autumn of 2026 is quoting a superseded spine point. Either the employer has not yet implemented the August 2026 agreement — in which case, since it is backdated to 1 April 2026, you should expect the uplift and arrears once it is processed — or the rate is genuinely locally set and disconnected from the spine, in which case you should ask directly whether it moves when the NJC settles. Casual staff on locally determined rates are the group most likely to be quietly left behind by a national settlement, because nobody is running their grade through a payroll uplift.

For context at the floor: the National Living Wage from April 2026 is £12.71 an hour for workers aged 21 and over, £10.85 for 18 to 20 year olds, and £8.00 for under-18s and most apprentices. Every advertised invigilator rate in our table clears it, but the margin at the bottom is thin — £12.85 is fourteen pence above the statutory minimum. Invigilation is, on the published numbers, a near-minimum-wage job carrying a significant amount of regulatory responsibility, and that tension is worth naming plainly.

Holiday pay and the casual contract trap

Nearly every invigilator advert mentions holiday pay, and the treatment varies enough to change your real earnings by more than 10%. It is worth understanding the arithmetic rather than skimming it.

Workers are entitled to 5.6 weeks of paid statutory annual leave. For someone with no fixed hours, that is commonly expressed as a percentage uplift on hours actually worked: 5.6 weeks of leave out of the 46.4 working weeks that remain in the year gives 12.07%. That is where the figure in so many adverts comes from, and it is the reason Plymstock and Westgate both quote exactly 12.07%. Some employers are more generous — St Peter's quoted 13%, reflecting a leave entitlement above the statutory floor.

The other thing a casual contract changes is everything around the rate. Casual and zero-hours invigilators are generally workers rather than employees, which means statutory holiday, National Minimum Wage protection and protection from unlawful deductions apply, but there is no guarantee of hours and, in most cases, no occupational sick pay and no redundancy rights. Pension auto-enrolment applies in the ordinary way once earnings cross the trigger, and will normally be into the Local Government Pension Scheme for directly employed school support staff or a workplace scheme for others — it is emphatically not the Teachers' Pension Scheme, whatever your day job is.

What JCQ says the job actually is

Here is the part that justifies the responsibility loading the pay does not reflect. Invigilation is not "watching a room". It is governed by a detailed public rulebook, the Instructions for Conducting Examinations, produced by the Joint Council for Qualifications on behalf of AQA, OCR, Pearson, WJEC/CBAC, CCEA and City & Guilds. The current edition is effective from 1 September 2026, it is free to download from jcq.org.uk, and anyone thinking about the job should read section 12 before applying.

JCQ defines the purpose of the role in four bullet points that are unusually clear about what is at stake:

"Invigilators have a key role in upholding the integrity of the external examination and assessment process. The invigilator's role is to ensure that the examination is conducted according to these Instructions, in order to: a. ensure all candidates have an equal opportunity to demonstrate their abilities; b. maintain the security of the examination materials before, during and after the examination; c. prevent possible candidate malpractice; d. prevent possible administrative failures."

Paragraph 12.9 sets out the core duties. Invigilators must be familiar with the Instructions; must give their full attention to conducting the examination properly; must always be able to see each candidate in the examination room; must be familiar with the JCQ Warning to Candidates, Information for Candidates and Unauthorised Items poster and any subject-specific instructions; and must inform the exams officer or head of centre of any concern about the security of question papers.

Paragraph 12.10 contains the sentence that explains why invigilation is more tiring than it looks:

"Invigilators must not carry out any other non-examination related tasks in the examination room. This also extends to reading the question paper."

You may not mark, plan, read, or look at your phone — with one exception, at paragraph 12.8(b): a lone invigilator may keep a mobile phone in the room solely to summon help without leaving or disturbing candidates, and it must be on silent. For two and a half hours your job is to watch, walk and notice. JCQ also states flatly that "CCTV cannot be used to invigilate candidates", which is the clearest possible statement that the presence of a human being is the point of the role.

Who is allowed to invigilate

JCQ places the duty on the head of centre and is deliberately non-prescriptive about qualifications, which is why the workforce is so mixed. Paragraph 12.8(c) requires the head of centre, a senior member of centre staff such as an assistant headteacher, or the exams officer to:

"ensure that all invigilators are suitably qualified and experienced adults who must not be current students at the centre. Although centres may decide who is suitably qualified and experienced, any relative, friend or peer of a candidate in the examination room must not be the sole invigilator"

Three things follow from that wording, and they matter more than they look.

• No qualification is specified. "Suitably qualified and experienced" is left to the centre. This is why retired teachers, parents, former administrators and people with no education background at all all end up in the same exam hall.
• Current students at the centre are barred outright. Not discouraged — barred.
• A relative, friend or peer of a candidate in the room may invigilate, but never alone. The rule is about sole invigilation, not about presence. In a small school where everyone knows everyone, this is a live constraint on rostering rather than a theoretical one.

There is also a specific provision for agency staff at paragraph 12.6, and it is stricter than most people assume:

"When contracting supply staff to act as invigilators, the head of centre must ensure that they are competent and fully trained, understanding what is and what is not permissible. An assurance from a recruitment agency, for example, would not be sufficient."

That last sentence is the reason agency invigilation pays a premium — the school cannot simply accept the agency's word and must train the person itself, so agency invigilators are more expensive and more administratively costly than the headline hourly rate suggests. It also explains why so many schools would rather recruit and keep a small permanent casual pool. Our guide to supply teacher pay covers the wider agency-versus-direct economics.

Finally, paragraph 12.7 requires that an invigilator be asked to declare whether they have invigilated previously and whether they have any current maladministration or malpractice sanctions applied to them. JCQ suggests centres devise a standard declaration template. If you are asked to complete one, that is the centre following the rules properly, not an accusation.

Can a teacher invigilate, and should they?

Teachers can invigilate, with one absolute restriction and several practical ones. Paragraph 12.8(d) requires the head of centre to:

"ensure that where the following individuals teach the subject being examined, they are not assigned as invigilators during an examination: a teacher, tutor, or senior member of centre staff."

The logic is obvious once stated — a teacher of the subject could, deliberately or otherwise, signal something about a question, and the integrity of the paper depends on that being impossible. The same paragraph creates a narrow exception: in exceptional circumstances a teaching assistant or learning support assistant who has supported one or more candidates in the room may act as an invigilator, but must not be the sole invigilator; and where such a person must invigilate a candidate accommodated in a separate room, another invigilator is required.

Two subject-specific carve-outs run the other way. Paragraph 12.11 notes that timed Art examinations will normally be invigilated by an Art and Design teacher, with additional invigilators deployed at the head of centre's discretion because the Art teacher may need to give technical assistance. Paragraph 12.12 requires a teacher of the subject to be present at the start of CCEA Science practical examinations to deal with technical difficulties and matters of safety.

Training and the competence test

Training is the one hard requirement JCQ places on centres in relation to invigilators, and it is stated four separate ways in section 12 because it matters. The opening line of the section states simply: "It is the responsibility of the head of centre to ensure that invigilators are appropriately trained in their duties."

From a candidate's point of view this is all invisible. From a new invigilator's point of view it means the training is not optional, is not a formality, and is the thing standing between you and a malpractice investigation if something goes wrong in your room. It is also, bluntly, a substantial amount of regulatory responsibility to attach to a rate fifty-seven pence above the bottom of the local government pay spine.

Ratios, rooms and access arrangements

The staffing requirements are specified precisely, and they explain both how many invigilators a school needs and why exams officers describe rooming as their single biggest headache.

• At least one invigilator for each group of 30 candidates or fewer sitting timetabled written examinations.
• At least one invigilator for each group of 20 candidates or fewer sitting timed Art examinations, timetabled CCEA Science practical examinations or WJEC GCE A2 Science practical examinations.
• Invigilators may be changed during the examination, provided the number present never falls below the required minimum.
• A lone invigilator must be able to get help easily without leaving the room or disturbing candidates — the sole permitted use of a mobile phone in the exam room, kept on silent.
• A "roving" invigilator is additionally required wherever an invigilator is also acting as a practical assistant, prompter, reader or scribe, entering the room at regular intervals to observe and support.
• Records of the seating plan, invigilation arrangements and attendance registers must be kept for every examination, retained until the review of marking deadline has passed or any enquiry is complete.

Access arrangements are where the staffing maths explodes, and it is the reason invigilator demand has risen faster than candidate numbers. A candidate with a reader, scribe, practical assistant or language modifier frequently needs a separate room, and JCQ repeatedly requires a separate invigilator where that happens — a candidate with their own reader accommodated in another room needs a separate invigilator; a candidate using a Sign Language Professional needs a separate invigilator; a candidate whose teaching assistant must act as invigilator in a separate room needs another invigilator as well. One candidate can therefore consume an entire invigilator for a whole session. The NAEO's own annual survey identifies arranging exam rooms, "largely due to the number of students awarded access arrangements", as the single most significant challenge reported by exams officers, alongside invigilator recruitment and training.

The exams officer: the properly graded job above it

If invigilation is casual hourly work at the bottom of the spine, the exams officer role is the substantive, graded, year-round post immediately above it — and the pay difference is large enough that anyone considering invigilation as a route into school work should understand it.

Real adverts on the DfE's Teaching Vacancies service in 2026 show an unusually wide spread for one job title:

The spread from roughly £19,700 to roughly £36,000 in actual pay for the same job title is the single most important thing to know about this role. Some of it is genuine differences in scope — a lead exams manager across a large multi-academy trust is doing a different job from a single-site exams officer in a small secondary. But a good deal of it is simply that there is no national job evaluation for the role, and individual employers grade it wherever their local structure happens to put it. Note also the Grade SC5 advert quoting £28,598 to £31,022: those are precisely the 2025/26 NJC values for spine points 12 and 17, which tells you the advert had not been repriced after the August 2026 settlement.

The NAEO — the National Association of Examinations Officers — runs an annual survey of the profession each October, drawing around 1,400 responses in its 2025 round, which it describes as roughly a fifth to a quarter of all exams officers. Its published findings report improved salaries as a positive development while identifying persistent concerns: rooming pressure driven by access arrangements, the burden of multiple awarding organisation systems and deadlines, invigilator recruitment and training, insufficient support at peak times, additional responsibilities piled on top of the core role, and a widespread sense of being undervalued.

What the hours actually look like

The hourly rate is only half the question. The other half — and the reason invigilation suits retired people, people with other flexible work, and almost nobody who needs a predictable income — is that the hours are extraordinarily uneven.

This is why adverts so consistently make availability across at least three days a week in May and June an essential requirement, and why they describe hours as negotiated for each exam period rather than fixed. A person taking a reasonable share of a summer series and some mock work might accumulate somewhere in the region of 60 to 120 hours across a whole year. At £13.28 an hour that is roughly £800 to £1,600 gross before holiday pay — which lands, by coincidence, in almost exactly the same annual bracket as a single exam marking allocation, for a similar total number of hours but spread very differently across the year.

Two consequences follow. First, invigilation is a supplement, not an income; nobody supports themselves on it, and adverts that imply otherwise are misleading by omission. Second, because the work is so concentrated, the marginal tax position matters: for a teacher's spouse or a retired teacher with a pension in payment, this income stacks on top of existing taxable income and is taxed at the marginal rate from the first pound if the personal allowance is already used. Our tax relief guide covers the employment expenses position, which for an invigilator is narrow.

Sources, and what we could not verify

The duties, ratios, training requirements and eligibility rules on this page are taken directly from the JCQ document Instructions for Conducting Examinations, effective from 1 September 2026, produced on behalf of AQA, OCR, Pearson, WJEC/CBAC, CCEA and City & Guilds, with paragraph numbers given where quoted. It is a free public download from jcq.org.uk, as is the companion Checklist for invigilators (for written examinations) and the Invigilation training checklist. Anyone considering this work should read section 12 in the current edition before applying, because it is reissued every year.

The pay spine figures are from the NJC national salary award circular dated 24 August 2026 and its annex of 2026/27 pay scales, showing a 3.3% uplift on spine points 3 to 43 implemented from 1 April 2026, the deletion of SCP 2 from the same date, and hourly rates derived by dividing annual salary by 52.143 weeks and then by 37 hours. The National Living Wage figures are the rates applying from April 2026. Individual advertised invigilator and exams officer rates are from dated 2026 vacancies on the DfE's Teaching Vacancies service, local authority education jobs boards and mainstream job boards, each attributed to the named employer. The exams officer workforce material is from the NAEO's published summary of its annual survey.

Four honest limitations.

• Job adverts expire. Every rate quoted was live in 2026 at the time we checked it, but vacancy pages are taken down and the figures cannot be re-verified indefinitely. They are illustrations of the market, not a durable scale.
• We could not obtain a published NAEO average salary. The public survey material describes salary movement qualitatively. We have not invented a number to fill the gap.
• NJC adoption in academies is common but not universal. Academy trusts are free to set their own support staff pay and some do. Where an advert names a purely local grade with no NJC reference, we cannot tell you whether it tracks the national spine, and neither can anyone but the employer.
• Scotland and Northern Ireland differ. The JCQ Instructions cover the JCQ member awarding bodies including CCEA in Northern Ireland, but the SQA operates its own invigilation regime in Scotland, and local government pay in Scotland is negotiated separately from the NJC. Our Scottish pay page covers the teaching side of that divergence.

Nothing here is employment or legal advice. If you are being asked to invigilate substantial hours inside your directed time as a teacher, or you believe a backdated NJC uplift has not reached your pay, those are questions for your union or your employer's HR team rather than for a web page.
