Bailly · Yvelines (78)

Bilingual school in the Yvelines, from 2 years old to A-levels

Athéna is a French-English bilingual school located in Bailly, in the Yvelines département (78), ten minutes from Versailles. Since 1991, we have been welcoming children from the age of 2 and supporting them all the way through to the French baccalaureate, in classes of a maximum of fifteen pupils.

Our approach to bilingualism is not based on hours of English classes added to a French curriculum, but on teaching delivered in both languages, by teachers who each speak in their mother tongue.

Learn in English, and not just English

The difference between a bilingual school and a school that teaches English well comes down to one thing: in a bilingual school, English is not a subject on the curriculum; it is the language of instruction.

At Athéna, from nursery school onwards and throughout primary school, children have the same number of lessons in French as in English. In practice, four half-days are taught in French and four in English, spread over two mornings and two afternoons to balance out the children’s concentration spans.

Each teacher teaches in their mother tongue. Pupils study language, mathematics (in nursery school), geography, science and art in both languages.

This is what allows a child who started at age 2 to acquire English as a second mother tongue, without any conscious learning effort.

Bilingualism at every level, in practical terms

Many parents ask us the same question: what happens to bilingualism after primary school?
Here is the actual route, stage by stage.

Nursery · from age 2

50/50 immersion

Four half-days in English, four in French, with native English-speaking educators. By the end of reception, the majority of children are reading in both French and English.

Primary School

The immersion continues

The 50/50 rhythm is maintained. Pupils prepare for the Cambridge Young Learners exams and sit them as soon as they are ready, following agreement with the family.

Lower secondary and year 11

Minimum of 6 hours per week

The programme is structured to provide a minimum of six hours of English per week, with ongoing preparation for the Cambridge exams. Support is tailored to each pupil’s level and pace.

Year 11 and Year 12

A level that certifies itself

The level achieved is reflected in Cambridge certifications and in application files for French and foreign universities.

A bilingual school in life-size

A maximum of fifteen pupils per class. This is essential for an immersion programme to work: in a larger group, the children who feel least at ease retreat into silence, and the immersion programme achieves nothing.

The school welcomes families of many nationalities. Global festivals punctuate the year: Halloween, Thanksgiving, Christmas, St Patrick's Day, Holi, Chinese New Year, and others depending on the cultures represented in the school.

Bilingualism continues outside of school hours, with an English club on Wednesdays and during the first week of the holidays, which is also open to children who do not attend the school.

Frequently asked questions about bilingual schools in the Yvelines

The answers to the questions parents ask us before choosing a bilingual school.

What is the difference between a bilingual school and a school that teaches English?

In a school that teaches English, English is a curriculum subject, generally two to three hours a week. In a bilingual school, English is a language of instruction: pupils study entire subjects in that language.

At Athena, nursery and primary school children spend as much time in English as in French, with teachers who instruct in their native language.

Does my child not speaking English mean they can join a bilingual school?

Yes. Athéna welcomes students of all language levels, including absolute beginners. The teachers draw up a personalised programme according to each individual's level.

The younger the child, the faster and more natural the acquisition, but integration remains possible at any age.

At what age should you enrol your child in a bilingual school?

The earlier the better: before the age of 6, a child acquires a second language using the same mechanisms as their mother tongue, without an accent and without conscious learning.

Athéna welcomes children from the age of 2, with the option of a nap.

Does a bilingual school prepare pupils for the French baccalaureate?

Yes. Athéna prepares pupils for the French brevet and general baccalauréat. As the school is independent (hors contrat), pupils sit all the exams at the end of the cycle rather than being assessed through continuous assessment, and they are entered for the exams by the school, not as private candidates.

They are also registered on Parcoursup, with dedicated support.

How to choose a bilingual school in the Yvelines?

Four criteria help to distinguish the institutions. The actual volume of teaching in English, to be checked in hours and not in intentions. The profile of the teachers, native speakers or not. The class size, which is crucial for a child to dare to speak.

And the continuity of the educational path, as many bilingual schools stop at primary or secondary level, which forces a change of school at the least opportune moment.
