44 A-levels with a June series in every year since 2023. Of their 169 components, 20 have carried identical boundaries in every one of those series. Almost all of those are coursework, practicals and speaking tests; the written papers are where the lines move.
Whole-qualification boundaries as a percentage of the maximum mark. Every strip on this page shares one scale, 45 to 95%, so a flat line is a boundary that did not move. Δ is the change on 2025 in percentage points; spread is the highest boundary minus the lowest across 2023 to 2026. Multi-route subjects (Drama and Theatre, Further Mathematics, History, Politics, Religious Studies) show one option route for the whole qualification, but every option paper is counted among their components, which is why History and Further Mathematics run high. June 2022 is left out of the line: that series carried pandemic adaptations. Source: Pearson Edexcel published grade boundaries (subject and notional component PDFs), June series.
