What Is a Bulge Class in Secondary School?

Published 17 February 2026

Introduction

When demand exceeds a school's Published Admission Number (PAN), local authorities may introduce a temporary "bulge class." This increases intake for one cohort, often by 30 additional pupils.

Families sometimes interpret this as evidence of permanent expansion. That assumption can be costly.

What a Bulge Class Actually Is

A bulge class is:

  • A one-off increase in Year 7 intake
  • Often driven by demographic spike
  • Not always repeated the following year

It does not necessarily mean long-term capacity growth.

The Property Risk

If you purchase within catchment during a bulge year, the expanded intake may create a wider cut-off distance temporarily.

In subsequent years, when intake reverts to standard PAN, cut-offs may contract again.

Evaluating Stability

Before making property decisions based on a recent generous cut-off:

  • Confirm whether intake increase was permanent
  • Check future PAN projections
  • Review multi-year admissions data

A single bulge year does not equal structural change.

Why Structured Modelling Matters

Our School Reports analyse multi-year intake patterns and borough demographic signals to help families determine whether widened cut-offs reflect lasting capacity or temporary bulge relief.
