How to read these numbers
What this data can and can’t tell you
•
The brevet. The diplôme national du brevet, taken at 15 at the end of collège: written exams in French, maths, history-geography, sciences and an oral, with the year’s coursework. We use the share of candidates who pass.
•
The bac. The baccalauréat at 18: general and technological in most lycées, vocational in lycées professionnels. Each is compared only with schools of its own kind.
•
Value added. The ministry’s own measure (IVAC for collèges, IVAL for lycées): a school’s pass rate minus the rate expected from its pupils’ social background and age. It is half of each school’s score in the grade.
•
Social position index (IPS). A summary of pupils’ family backgrounds from parents’ occupations, about 100 for the average French pupil. Shown for context; never graded.
•
Within 5 km. French families don’t pick a school by the town’s name: a collège serves a catchment set by the département, a lycée one set by the académie. So the grade uses the schools within 5 km of where the town’s residents live, and neighboring towns can share them.
•
Primary schools. Not graded: national tests (évaluations nationales) aren’t published school by school. The commune’s primary schools are listed.
They grade C−, better than those around 19% of compared French towns and #66 of 94 in Essonne. In 2025, 80.9% of the 2,476 candidates at the 17 collèges within 5 km passed the brevet (−4.4 pts against the expected rate). At the lycées, 90.0% of 2,900 candidates passed the bac (as expected).
Which collège near Chilly-Mazarin does best?
Against the expected rate, Collège Jean Mermoz (public, 2.3 mi): 72% of 67 candidates passed the brevet in 2025, +9 pts against the rate its pupils’ backgrounds predict. On the raw pass rate alone the order can differ; value added is the fairer comparison.
Which lycée near Chilly-Mazarin does best?
Against the expected rate, Lycée professionnel Gustave Eiffel (public, 2.6 mi): 90% of 119 candidates passed the vocational bac in 2025, +10 pts against the rate its pupils’ backgrounds predict.
How do children get a place at a collège near Chilly-Mazarin?
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.
Are primary schools in Chilly-Mazarin graded?
No: France doesn’t publish primary results school by school. Chilly-Mazarin has 10 primary schools (écoles maternelles and élémentaires), listed above.
