When a family applies to Henri-IV or Louis-le-Grand in Paris, they come up against a very real obstacle: the number of places available compared with the volume of applications. France’s most selective high schools are not selective solely because of their baccalaureate results. They are difficult to get into because of a complex mix of admissions rules, limited capacity and students competing directly for places.
Affelnet and the admissions points system: the filter rankings don’t show
People often talk about the “best high schools” based on their baccalaureate pass rates. This oversimplification obscures a decisive factor: admissions are handled through Affelnet-lycée, an algorithm that allocates places according to a points system specific to each education authority.
This points system takes academic results into account, but also geography. Students who live in a high school’s catchment area receive a points bonus that can make the difference between being admitted and being turned away. Your residential catchment area carries as much weight as your grades in Affelnet.
In practice, a student with excellent grades who lives outside the catchment area may be denied a place at a school where a student with slightly lower grades but an address within the right area is admitted. Among the hardest high schools to get into, catchment-area rules account for a considerable share of the actual selectivity.
The number of places available also varies from year to year, depending on departures and the school’s physical capacity. A high school can suddenly become more selective simply because it has lost a class.
Selective Paris high schools: Henri-IV, Louis-le-Grand and private schools under contract
In Paris, the concentration of prestigious schools creates an unusual level of competition. Henri-IV and Louis-le-Grand, both public, have 100% baccalaureate pass rates, with honors rates close to or above 96%. Their appeal draws applications from well beyond their catchment areas.
Among private schools under contract with the state, Saint-Louis-de-Gonzague, Stanislas and Fénelon Sainte-Marie achieve comparable results. Private schools under contract dominate the top of national rankings, with honors rates close to 97 or 98%.
The difference between public and private schools lies in how they select students. Private schools choose students based on their application, an interview and sometimes recommendations. Public schools, by contrast, use Affelnet, meaning selection is algorithmic rather than discretionary. In both cases, the result is the same: a rigorous admissions process.
Beyond Paris: Hoche in Versailles and Du Parc in Lyon
Selectivity is not limited to the capital. Lycée Hoche in Versailles and Lycée Du Parc in Lyon are among the most sought-after public high schools in France, with baccalaureate results on a par with the best Parisian schools.
Hoche and Du Parc compete with the most prestigious Paris high schools. Their appeal extends beyond their home education authorities, thanks in particular to their preparatory classes for the grandes écoles, which act as a second selection filter after the baccalaureate.
Admission to the 10th grade or entry to a preparatory class: two different kinds of selectivity
People often conflate two different realities when they talk about a “hard-to-get-into high school.” Admission to the 10th grade, regulated by Affelnet, follows regional rules. Admission to a preparatory class, on the other hand, goes through Parcoursup and is based on the student’s academic record.
Louis-le-Grand’s CPGE programs rank among the top on Parcoursup for the average grades of admitted students. The preparatory classes at Louis-le-Grand and Henri-IV select from among the country’s strongest applications. Schools such as Sainte-Geneviève in Versailles set similarly high standards for their post-baccalaureate programs.
A high school may therefore be relatively accessible in the 10th grade but extremely selective at preparatory-class level. This is the case for several schools outside major cities that do not appear in “best high schools” rankings, but whose CPGE programs turn down the vast majority of applicants.
Regional inequalities and actual access to selective high schools
National rankings mask a structural problem. In some departments, students simply have no access to a selective high school, regardless of how strong their application is.
The Institut des politiques publiques found that in Seine-Saint-Denis, 23 of the 35 areas studied offer only one priority 1 high school. More than half of the department’s young people have access to just one priority high school. In practice, this limits their ability to aim for a prestigious school without an exemption from the school catchment-area rules.
Obtaining an exemption is still a complicated process. The reason must be accepted (a particular educational pathway, proximity to a parent’s workplace, or a sibling already enrolled at the school), and places must be available at the school in question. In practice, exemptions are rarely granted for the most sought-after high schools.
What makes a high school truly selective
A school’s selectivity results from a combination of factors, not a single indicator:
- The ratio of applications to available places, which can vary each year depending on cohort sizes and the opening or closure of classes
- The Affelnet points system used by the education authority, including geographic bonuses, academic results and social criteria
- The availability of attractive post-baccalaureate programs (CPGE, rare BTS programs), which strengthen the school’s overall reputation and increase pressure for admission to the 10th grade
- Whether the school is public or private under contract, which determines whether selection is algorithmic or discretionary
So getting into a school is not simply a matter of meeting a minimum grade average. It depends on where you live, the education authority, the number of applicants that year and the type of program you are applying for. A school ranked first for baccalaureate results may be easier to get into than a lower-ranked school in an area where demand far exceeds the limited number of places available.
