# Determining primary school capacity: guidance for local authorities

Guidance on the determination of the capacity of primary schools, with the aim of providing a consistent approach to calculating the capacity.

### 3. Worked Examples

Example 1:

In this example there are 10 class bases to be included in the Capacity calculation.
The area of each room is divided by 1.7m 2 to determine the maximum number of pupils which can be accommodated in the room based on size.
A realistic class distribution is then applied and the Planning Capacity determined by applying class size maxima.

To calculate Working Capacity for a specific school session, the assigned class distribution for that session is applied.
Working Capacity is then calculated by applying class size maxima.

Example 2:

In this example there are 5 class bases to be included in the Capacity calculation.

The area of each room is divided by 1.7m 2 to determine the maximum number of pupils which can be accommodated in the room based on size. A realistic class distribution is then applied and the Planning Capacity determined by applying class size maxima.

To calculate Working Capacity for a specific school session, the assigned class distribution for that session is applied. Working Capacity is then calculated by applying class size maxima.

*In this case, the Working Capacity of one of the rooms has been adjusted to allow for a full class to be accommodated. The metric has not fallen below 1.5m 2 per pupil.

Example 3:

In this example there are 16 class bases to be included in the Capacity calculation.

The area of each room is divided by 1.7m 2 to determine the maximum number of pupils which can be accommodated in the room based on size. A realistic class distribution is then applied and the Planning Capacity determined by applying class size maxima.

To calculate Working Capacity for a specific school session, the assigned class distribution for that session is applied. In this case, a Local Authority policy on P1 intake levels has been applied, showing a maximum of 15 pupils per P1 class.

Example 4:

In this example there are 13 class bases to be included in the Capacity calculation.

The area of each room is divided by 1.7m 2 to determine the maximum number of pupils which can be accommodated in the room based on size. A realistic class distribution is then applied and the Planning Capacity determined by applying class size maxima.

To calculate Working Capacity for a specific school session, the assigned class distribution for that session is applied. This example shows how this could differ from year to year. Working Capacity is then calculated by applying class size maxima.
