Introduction

For most academies, their autumn census return forms the basis for calculating pupil-led funding for the following academic year. In some cases, we use estimated pupil numbers if the academy’s funding agreement includes a clause to this effect.

The funding agreement clause may be conditional, and an academy’s allocation is funded on estimates until certain conditions are met. This is usually until all year groups are present. Once these conditions are met, the autumn census becomes the basis for future funding.

Special and alternative provision academies are not funded on estimates as the number of high needs places forms the basis of their general annual grant. More information on how high needs places are funded is available in the high needs funding arrangements: 20242025 to 20252026.

Estimating pupil numbers data collection

Institutions provide their estimated pupil numbers in October each year, using an online form via the Department for Education (DfE) sign in.

We have now published information on how to complete the estimating pupil numbers data collection.

Once agreed, estimated pupil numbers are used to calculate the academy’s budget. We review them to ensure they are reasonable, and that evidence supports any significant changes in numbers. However, where an increase in pupils relates to basic need, this is funded by the local authority and should not be reflected in the estimates an institution provides to us.

If an academy does not provide their estimated pupil numbers, we will use the most recent census data to calculate their funding. If they are a growing school that is still adding year groups, this can result in a funding shortfall.

Pupil number adjustment (PNA)

Where we initially fund academies based on estimated pupil numbers, we include them in the annual PNA exercise during the academic year. The PNA exercise determines if adjustments are required to bring initial funding allocations into line with the actual pupil numbers that schools record in the autumn (October) school census.

Some estimate-funded academies have funding agreements with a PNA threshold, where no adjustment will occur if actual pupil numbers vary by more or less than a specified percentage. If an academy’s estimate of pupil numbers is outside the threshold, or no threshold applies, we adjust funding through the PNA process. This results in either an increase or decrease in funding.

We use an academy’s estimated pupil numbers, and the pupil led funding they receive to produce per-pupil funding rates for the academic year. This average figure will be adjusted downwards for academies delivering T Levels within 16 to 19 provision to exclude the relevant T Level funding. We multiply the difference in actual pupil numbers by the per-pupil rates, taking account of any threshold, to determine the required adjustment. As in previous years, we run the calculation separately for pre-16 school budget share and 16 to 19 funding, and then combine the results into a single overall adjustment.

Where local authorities have already funded growth in pre-16 pupil numbers to meet basic need, we will deduct the amount they have paid from any positive PNA to ensure that academies are only funded for the growth once.

PNA calculator for 20242025 to 20252026

You can use our PNA calculator with the figures you have for your academy to estimate your own adjustment. By inputting your own projected numbers, it can also provide a reasonable estimate for future years, to inform your longer-term budget planning.

Academies in scope of PNA receive their statements in May. Academies receive payment of any positive adjustments in July. PNA recoveries start from September, in the following academic year.
