If you work as school support staff in the UK, your salary may look very different from the full-time equivalent salary shown in a job advert. This is especially common when you work part time or on a term-time-only contract.
A school may advertise a role with a full-time equivalent (FTE) salary of £25,000, for example, but you might receive less because you work fewer hours and fewer weeks during the year.
This is where pro rata pay comes in.
A pro rata calculation adjusts a full-time salary to reflect your actual working hours, working weeks and contractual arrangements. For school support staff, the calculation can also involve annual leave and school closure periods.
This guide explains how pro rata pay works, how to calculate it, what “term time only” means, and how to check whether the salary in a school job advert is likely to be your actual annual salary.
What Does Pro Rata Mean for School Support Staff?
“Pro rata” means in proportion.
If a full-time employee earns a particular salary for working full-time hours and weeks, a part-time employee doing fewer hours will normally receive a proportion of that salary.
For example, suppose a school advertises:
| Employment detail | Full-time role |
|---|---|
| FTE salary | £28,000 |
| Full-time hours | 37 hours per week |
| Your hours | 18.5 hours per week |
If you work exactly half the full-time weekly hours, your basic annual salary would generally be 50% of the FTE salary:
£28,000 × 18.5 ÷ 37 = £14,000
However, this is only a straightforward part-time calculation.
For school support staff working term time only, you may also work fewer weeks than a full-time, all-year employee. Your actual contractual salary can therefore be lower than the simple hourly or weekly proportion.
The exact calculation depends on your contract, school or local authority arrangements and how annual leave is treated.

School support staff include many roles that help schools operate without being teaching positions.
Examples include:
- Teaching assistants
- Higher-level teaching assistants
- Administrative staff
- School receptionists
- Premises and maintenance staff
- Catering staff
- Cleaners
- Learning support assistants
- Pastoral support workers
- Lunchtime supervisors
- Technicians
- Finance and office staff
The employment arrangements can vary considerably between schools.
Some employees work throughout the year but on reduced hours. Others work only during school terms. Some roles may be covered by local authority terms and conditions, while academies and other employers can have their own arrangements.
The National Joint Council (NJC) Green Book is particularly important for many local-government school support roles. The Local Government Association explains that the Green Book covers pay and conditions for local authority employees and can also be used for some non-local-authority staff.
Full-Time Salary vs Pro Rata Salary
One of the most important things to understand when looking at a school vacancy is the difference between FTE salary and actual salary.
Full-time equivalent salary
The FTE salary shows what the employee would earn if they worked the employer’s full-time hours and the full contractual working year.
Pro rata salary
The pro rata salary reflects the actual working arrangement.
For example:
| Salary information | Amount |
|---|---|
| Full-time equivalent salary | £30,000 |
| Full-time hours | 37 hours |
| Part-time hours | 22.2 hours |
| Hours proportion | 60% |
| Basic pro rata salary | £18,000 |
The calculation is:
£30,000 × (22.2 ÷ 37) = £18,000
This example assumes the employee works throughout the contractual year.
A term-time-only employee can have a different calculation because they may not work during school holidays.

A term-time-only (TTO) employee normally works during periods when the school is open and does not work during school closure periods, subject to the terms of their contract.
For example, a teaching assistant might work:
- Monday to Friday
- 6 hours per day
- During school term dates
- With school holidays not forming part of their normal working weeks
The employee still has an entitlement to paid annual leave. The way that entitlement is accounted for depends on the employment arrangement.
Under NJC arrangements, term-time-only employees are principally employed to work during periods when schools are open. Southwark’s schools HR guidance, referring to the NJC Green Book, explains that TTO employees work a reduced number of weeks and accrue a pro-rata entitlement to paid leave.
This is why you should not simply take an FTE salary and multiply it by the number of term weeks. Holiday entitlement and other contractual provisions can affect the final figure.
How to Calculate Pro Rata Pay for School Support Staff
There are usually two important factors:
- Hours worked compared with full-time hours
- Weeks worked compared with the full contractual year
A simplified calculation is:
Pro rata salary = FTE salary × hours fraction × weeks fraction
However, for term-time-only employees, the weeks figure may need to account for paid annual leave and other contractual arrangements.
Example 1: Part-Time, All-Year School Support Staff
Suppose a school administrator has:
- FTE salary: £29,000
- Full-time hours: 37 hours per week
- Contracted hours: 18.5 hours per week
- Works all year
The employee works 50% of full-time hours.
£29,000 × 18.5 ÷ 37 = £14,500
The estimated annual salary is therefore £14,500 before tax and other deductions.
Example 2: Term-Time-Only Teaching Assistant
Now suppose a teaching assistant has:
- FTE salary: £27,000
- Full-time hours: 37 hours per week
- Actual hours: 18.5 hours per week
- Works during school terms only
The hours fraction is:
18.5 ÷ 37 = 0.5
The equivalent salary based only on hours would be:
£27,000 × 0.5 = £13,500
But this does not automatically mean £13,500 is the final contractual salary.
Because the employee works term time only, the employer may calculate the annual salary using the number of working weeks plus the employee’s paid annual leave entitlement.
This distinction is important when comparing school job adverts.
Why Term-Time-Only Employees Can Still Receive Holiday Pay
A common misunderstanding is that someone who does not work during school holidays does not receive holiday entitlement.
That is not generally correct.
Workers are legally entitled to 5.6 weeks of statutory paid holiday each year, subject to the applicable rules. Part-time employees receive holiday entitlement in proportion to their working pattern. (Acas)
For school support staff, annual leave can be handled differently from a normal all-year employee because the employee may not work during school closure periods.
The employment contract should explain how holiday entitlement and pay are dealt with.
This is particularly important because school holidays are not automatically the same thing as annual leave. Some closure periods may be incorporated into the way a term-time-only salary is calculated.

Imagine a school support worker has:
- FTE salary: £26,000
- Full-time working week: 37 hours
- Actual working week: 18.5 hours
- Contract: term time only
First calculate the hours proportion:
18.5 ÷ 37 = 0.5
Then calculate the full-year equivalent based on hours:
£26,000 × 0.5 = £13,000
The employee’s term-time salary will then depend on the contractual working weeks and the treatment of paid annual leave.
For this reason, the salary shown in a vacancy might appear as:
£26,000 FTE, £13,000 pro rata
or it might show a different actual salary for a term-time-only contract.
Always check the wording of the vacancy rather than assuming the FTE salary is what you will receive.
What Does “FTE” Mean on a School Job Advert?
FTE means Full-Time Equivalent.
If a job advert says:
Salary: £28,000 FTE, £17,500 pro rata
the £28,000 figure represents the full-time equivalent salary.
The £17,500 figure is the advertised salary applicable to the specific working arrangement.
This distinction is particularly useful when comparing several school support jobs.
For example:
| Job | FTE salary | Advertised salary |
|---|---|---|
| Teaching Assistant | £27,000 | £18,000 pro rata |
| School Administrator | £29,000 | £21,000 pro rata |
| Pastoral Assistant | £30,000 | £15,000 pro rata |
The highest FTE salary does not necessarily give the highest actual annual income. Hours and weeks worked matter too.
School Support Staff Pay and the NJC Green Book
Many school support staff employed by local authorities are covered by the National Joint Council for Local Government Services, commonly known as the NJC.
The Green Book sets out national terms and conditions for local government services. The framework covers a wide range of employees, including school-related roles.
The 2026 NJC pay offer provides for a 3.30% increase from 1 April 2026 on NJC pay points 3 to 43, according to the Local Government Association’s employer circular. The offer also states that it applies to school support staff currently covered by NJC collective bargaining arrangements.
However, you should not assume that every school support worker in the UK is paid under the same system.
Academies, independent schools, contractors and other employers may use different pay arrangements.
There are also differences across the UK. The re-establishment of the School Support Staff Negotiating Body is an England-specific development, while different arrangements continue to apply in Wales, Scotland and Northern Ireland.
How Many Weeks Does a Term-Time Employee Work?
The number of working weeks depends on the contract.
A school may advertise a role as:
- 38 weeks per year
- 39 weeks per year
- 40 weeks per year
- Term time plus specified training days
The phrase “term time only” does not automatically mean exactly 39 weeks.
For example, a contract could require an employee to work during school terms plus several additional training or inset days.
That is why a pro rata calculator should use the actual contractual weeks rather than relying on a standard assumption.
Read More: Pro Rata Calculator UK-Commission Pay ExplainedHow to Calculate Your Hourly Rate
Once you know your annual salary and contractual hours, you can estimate the underlying hourly rate.
A basic calculation is:
Hourly rate = annual salary ÷ annual contracted hours
Suppose a school support worker earns £18,000 and works:
- 20 hours per week
- 39 working weeks per year
Annual working hours are:
20 × 39 = 780 hours
Estimated hourly rate:
£18,000 ÷ 780 = £23.08 per hour
However, be careful when comparing this figure with an FTE hourly rate. If the annual salary includes paid holiday or other contractual elements, simply dividing by the hours physically worked can produce a different figure from the employer’s underlying pay rate.
For payroll and contractual questions, the employer’s calculation should take priority.
What Should You Check in a School Job Advert?
Before accepting a school support staff position, look for these details:
| Item | Why it matters |
|---|---|
| FTE salary | Shows the full-time equivalent |
| Actual salary | Shows what the advertised role may pay |
| Weekly hours | Determines the hours proportion |
| Working weeks | Important for term-time contracts |
| Term-time only | Indicates school-based working pattern |
| Training/inset days | May add working days |
| Annual leave | Can affect the pro rata calculation |
| Pay scale/grade | Shows how the role is positioned |
| Contract type | Permanent, temporary or fixed-term |
| Pension | May affect your overall employment package |
If the advert only provides an FTE salary and does not state the actual pro rata amount, ask the school or HR department for the contractual annual salary before making a decision.
Pro Rata Pay and Monthly Salary
A common question from school support staff is:
“If I know my annual pro rata salary, how much will I receive each month?”
If your contractual annual salary is £18,000 and it is paid evenly over 12 months:
£18,000 ÷ 12 = £1,500 per month
This is your gross monthly pay, before Income Tax, National Insurance, pension contributions and any other deductions.
Some school employees receive an even monthly salary throughout the year even though they only work during school terms. This can make budgeting easier because income does not stop during school holidays.
Your payslip and employment contract should confirm how your salary is distributed.
Does Pro Rata Pay Affect Your Pension?
It can affect the amount you contribute because pension contributions are generally linked to pensionable pay and the applicable pension scheme rules.
Many local authority school support employees are members of the Local Government Pension Scheme (LGPS), although eligibility and pension arrangements depend on the employer and role.
If your salary changes because you work fewer hours, your pensionable earnings may also change.
For an accurate pension estimate, check your employer’s pension scheme rather than relying solely on a pro rata salary calculator.
Pro Rata Pay vs Hourly Pay
These terms are related but not identical.
Pro rata salary tells you how a full-time salary is adjusted for a particular working arrangement.
Hourly pay tells you how much you are paid for an hour of work.
For example, two school support staff members could have different annual salaries because one works more weeks per year, even if they have the same underlying hourly rate.
This is why comparing only annual salary can sometimes be misleading.
When comparing jobs, look at:
FTE salary + weekly hours + working weeks + holiday arrangements + actual annual salary.
How a Pro Rata Calculator UK Can Help
A Pro Rata Calculator UK can provide a quick estimate when you are comparing a full-time salary with a part-time or term-time role.
You can usually enter:
- Full-time annual salary
- Full-time weekly hours
- Your weekly hours
- Number of working weeks
- Relevant holiday or contractual information
The calculator can then help you estimate the annual pro rata salary and, where appropriate, monthly or weekly pay.
For school support staff, the calculator is particularly useful when a vacancy lists an FTE salary but you want to understand the approximate value of the actual job.
However, a calculator should be treated as an estimate unless it is specifically designed around your employer’s contractual calculation method.
Common Mistakes When Calculating School Support Staff Pay
Mistake 1: Using the FTE salary as your actual salary
An FTE salary is not necessarily what you will receive if you work part time or term time only.
Mistake 2: Ignoring working weeks
A role working 20 hours for 39 weeks is different from a role working 20 hours throughout the year.
Mistake 3: Treating school holidays as automatically unpaid
The contract may include paid annual leave within the overall term-time calculation.
Mistake 4: Assuming every school uses the same pay system
Local authority schools, academies and other employers may have different contractual arrangements.
Mistake 5: Calculating take-home pay from gross salary alone
Income Tax, National Insurance, pension contributions and other deductions can change your actual take-home pay.
What does pro rata mean for school support staff?
Pro rata means that a salary or entitlement is adjusted in proportion to the employee’s working arrangement. For school support staff, this can depend on both weekly hours and the number of weeks worked.
Is a term-time-only salary pro rata?
Usually, yes. A term-time-only employee normally works fewer weeks than an all-year employee, so their salary is adjusted accordingly. Paid annual leave must also be considered.
Are school holidays paid for support staff?
It depends on the employment contract. Term-time-only employees can have paid annual leave included in their overall salary calculation even though they do not normally work during school closure periods.
What is an FTE salary?
FTE stands for Full-Time Equivalent. It shows the salary that would apply to a full-time employee under the relevant working arrangement. Your actual salary may be lower if you work fewer hours or weeks.
Can I calculate my school support staff salary myself?
Yes. You can estimate basic pro rata pay by comparing your contracted hours and working weeks with the full-time arrangement. For term-time-only jobs, however, holiday entitlement and contractual rules can make the calculation more complicated.
Does part-time work reduce holiday entitlement?
Part-time workers are still entitled to statutory paid holiday. The entitlement is normally proportional to their working pattern. The statutory minimum is 5.6 weeks per year, subject to the applicable rules.
Does overtime affect school support staff pay?
It can. Overtime arrangements depend on the employment contract and employer policy. There is no automatic legal right to an overtime premium, although employers must ensure applicable minimum wage requirements are met.
Final Tips for School Support Staff
If you are considering a school support role, do not judge the salary by the FTE figure alone.
Check your:
- FTE salary
- Actual weekly hours
- Number of working weeks
- Term-time or all-year status
- Annual leave entitlement
- Additional training or inset days
- Pay scale and employer
- Pension arrangements
- Actual annual salary
- Expected monthly gross pay
The most important figure is the salary you are contractually entitled to receive, not simply the headline FTE salary.
For a quick estimate, a Pro Rata Calculator UK can help you understand how your school support staff salary changes when you work fewer hours or weeks. For the final figure, always check your employment contract, job offer and payroll information because individual school arrangements can differ.
