Exam Invigilator Payslip Explained

There is no national binding pay scale for exam invigilators. Schools, colleges and universities set their own rates, which means an invigilator can move between institutions and find rates differ by several pounds an hour. Most employers base their rate loosely on the lower end of the NJC Green Book support-staff spine, often equivalent to SCP 3 to SCP 5, which for 2025/26 ran from approximately £25,183 to £26,835 a year pro-rata after the April 2025 award - but those rates are converted to an hourly figure for casual work, and in any case the rate must not fall below the National Living Wage floor (£12.71 an hour for workers aged 21 and over from April 2026). Always confirm the precise rate in the written statement of particulars or the engagement letter that the school is required to give you.

Invigilators are most commonly engaged on zero-hours contracts, sometimes called casual contracts. This means the employer is not obliged to offer a minimum number of hours, and the worker is not obliged to accept any offered session. Work is concentrated in May and June (GCSE and A-level season), with smaller peaks in January (January series resits and vocational quals) and sometimes in November. Outside exam seasons, many invigilators do not work at all, so annualised income can be very low - well below the auto-enrolment earnings trigger of £10,000, which remained unchanged for 2026/27.

From April 2024 onwards, rolled-up holiday pay became the lawful default for irregular-hours and part-year workers, including zero-hours invigilators, for leave years starting on or after that date. Rolled-up holiday pay adds 12.07 percent to the worker's regular pay (12.07 percent being 5.6 weeks of holiday divided by the remaining 46.4 working weeks) and pays it alongside the session rate. Critically, it must be separately itemised on the payslip as "holiday pay" - it cannot simply be blended into the hourly rate without labelling. If your payslip shows a flat rate per session with no holiday line, ask whether holiday pay is included and how it is calculated.

Some employers still operate the alternative method: accruing holiday pay separately, not adding it to the session rate, and paying it out when the invigilator actually takes annual leave or when the engagement ends. Under this method the payslip shows only the base hourly rate and the holiday pay is held in a notional pot. Both methods are lawful, but you should know which applies to you, because if holiday pay is being accrued separately, you are entitled to claim it even if the school has never mentioned it.

An invigilator payslip is typically one of the shortest in the education sector. The payments block usually shows: a basic-pay or session-rate line giving the hourly rate multiplied by hours worked; and, if the employer uses rolled-up holiday pay, a separate holiday-pay line at 12.07 percent of the basic pay. Some schools pay a flat session rate (for example, a half-day morning examination) rather than an hourly rate - in that case the line shows the session rate times the number of sessions.

The deductions block usually shows only PAYE tax (if earnings in this pay period plus year-to-date earnings exceed the personal allowance) and employee National Insurance (if earnings in this period exceed the primary threshold). Because invigilators are paid weekly or per-session and earnings are irregular, it is common for some payslips to show no deductions at all and others to show both tax and NI, depending on the volume of sessions in that period. This is normal; both PAYE and NI are calculated on each pay period independently for workers below the NI threshold, not cumulatively across the year.

Because annual earnings typically fall well below the 10,000 pound auto-enrolment trigger, most invigilators will not see any pension deduction. However, you have the right to opt into the employer's auto-enrolment scheme even if your earnings are below the trigger - the employer is not required to contribute if you are below the lower qualifying earnings limit (£6,240 for 2026/27), but they must enrol you if you request it. If your earnings from all sources mean pension saving is relevant to you, speak to the employer's payroll team.

The year-to-date column is useful for confirming that your total gross for the tax year is correct and for checking whether you have accumulated enough earnings to cross the personal allowance (£12,570 for 2026/27). Many invigilators earning well below this amount will find their tax code produces no PAYE deduction at all - which is correct. If you have other employment and your invigilator work is a second job, check that the correct code is applied: a BR code (basic rate, no allowance) would be normal if your allowance is already used elsewhere.

Automatic enrolment requires employers to enrol workers into a workplace pension if they earn above the earnings trigger - set at £10,000 a year for 2026/27 and unchanged from 2025/26. Most exam invigilators, working a handful of sessions per year, will earn significantly less than this and so will not be automatically enrolled. If you are not enrolled, you will see no pension deduction on your payslip, and that is correct.

Even below the trigger, you have the right to opt in to the employer's auto-enrolment scheme by writing to the employer. If you opt in and your total pay (across all sources) places you within the qualifying earnings band (between £6,240 and £50,270 for 2026/27), the employer must pay the statutory minimum employer contribution of 3 percent, and you pay at least 5 percent. However, if your total invigilating earnings fall below £6,240 across all pay periods with that employer in the year, no contributions are due even if you have opted in.

If invigilating is a second job alongside a main employment that already has a pension, your main employer handles the auto-enrolment obligation. The invigilating employer treats you as a second-job worker and, unless you opt in, has no pension obligation.
