Each cohort is shown separately with its own respondent count (n). Cohorts are not pooled or averaged: On Track’s coverage changed sharply after 2021, so a single figure across them would show a movement that did not happen.

On Track is a voluntary survey and its coverage varies widely between schools. A percentage from a small number of respondents carries a wide margin of error, so read every figure against the respondent count above it. Cohorts are never pooled: coverage changed sharply after 2021, and combining them would show a movement that did not happen.
