About This Data
- •Schools are ranked by their Attainment 8 score, which shows overall exam results. This data comes from the Department for Education performance tables.
- •Exam results and progress scores tell you different things. Imagine two children climbing a mountain: one starts at the bottom and climbs halfway up, while another starts a third of the way up and climbs another third. The second child climbed less distance but finished higher up. Exam results show where pupils finished (like height on the mountain), while progress scores show how far they've come since primary school (like distance climbed). Progress scores help you understand how much a school has helped pupils improve, regardless of where they started.

Pupils per Teacher or Teaching Assistant
Shows how many children each teacher looks after on average. The lower line includes teaching assistants, giving you a better picture of the adult support available in classrooms.
Total Pupils
The number of children enrolled at this school over time. These figures come from financial records and may differ slightly from other pupil numbers on this site due to when data was collected.
Total Number of Teachers
The total teaching capacity at this school, including classroom teachers and senior staff who also teach. Part-time teachers are counted based on their working hours.
Teaching Assistants
Support staff who work directly with children in classrooms. This includes regular TAs, higher-level TAs with more responsibilities, and specialist support for children with additional needs.
Teachers with Qualified Teacher Status (%)
The percentage of teachers who have completed official teacher training in England. A higher percentage typically indicates a more experienced and formally trained teaching team.

Non-classroom Support Staff and Auxiliary Staff
Office and admin staff who keep the school running smoothly, plus auxiliary staff like catering teams and site maintenance who look after the building and meals.
Total Headcount and Workforce
Two ways of counting staff: headcount shows total people employed (including part-timers), while workforce counts the equivalent number of full-time positions.
About This Data
- •Data sourced from the DfE School Workforce Census. Numbers may not match exactly other data shown on this site due to different collection timings within the academic year.
- •FTE = Full-time equivalent, representing the total working hours divided by standard full-time hours. Headcount = total number of individuals employed.

Finances
2023/24
Income per Pupil (£)
In 2023/24 the revenue reserve was £541,000 or £371 p/pupil. Schools maintain reserves for unexpected costs, but these funds are ultimately meant to benefit pupils.
Expenditure per Pupil (£)
In 2023/24 the in-year balance was -£394,000 or -£270 p/pupil. A negative balance means the school spent more than it received, covered by drawing on reserves.
About This Data
- •Financial data comes from the DfE School Financial Benchmarking service. Schools report their income and spending each year.
- •Revenue reserve is the money a school has saved up over time. Schools keep reserves to cover unexpected costs, though funds are meant to benefit current pupils.
- •In-year balance shows whether a school spent more or less than it received in a single year. A positive balance means the school had money left over; a negative balance means it dipped into savings.
