Against every compared French town with a collège or lycée within 5 km.
The collèges lift L'Isle-Adam; the lycées hold it back.
The grade uses every collège and lycée within 5 km of L'Isle-Adam with 2025 results and value added, public and private under contract: 5 collèges (590 candidates) and 1 lycée (416). Each school’s pass rate and value added are compared with every French school of its kind, then weighted by candidates; collèges and lycées count equally. A school can count for several towns.
The line is the typical French school for each social position index; the band holds the middle two-thirds. A dot’s color is the ministry’s value added.
Schools whose pupils come from better-off homes usually get higher pass rates. The ministry’s value added already allows for that, and for pupils’ ages: of the 5 schools here, 1 are 2 points or more above the expected rate and 2 2 points or more below.

IPS: DEPP’s social position index, 2024–25, from parents’ occupations (France’s average pupil ≈ 100). It describes; it doesn’t grade. Value added: the school’s pass rate minus the rate expected from its pupils’ backgrounds and ages.
The dashed circle is 5 km (3 miles) from the town’s point, the center of where its residents live; the black outline is the commune.
Points: the Ministry of Education’s school directory.
Each with its 2025 result and its value added: how far its pass rate is above or below what the ministry expected from its pupils. 5 collèges and 1 lycée are in the grade. Distances from the town’s point.
Results: DEPP, brevet (IVAC) and bac (IVAL) 2025. Not in the grade: a school with results but no value added published (often a small one). Primary schools: the commune’s own, from the school directory.

A state collège takes the children of its catchment area (secteur), which the département council sets; families can ask the académie for an exception (dérogation). Lycée places go through the académie’s Affelnet assignment. Private schools under contract admit pupils themselves.
