Frequently asked questions

Everything you need to know before enrolling your child

Does my child need to speak English to enrol?
No, it's not compulsory. At IS33, we welcome students of all language levels. In kindergarten, total immersion allows for natural learning. For older children, we offer French as a Foreign Language (FLE) or English support courses to facilitate integration.
How many pupils are there in each class?
We prefer small classes for personalised attention. Our average class size is 20 pupils in kindergarten (with 2 supervisors) and approximately 15-20 students in collège and lycée, this ensures that each child receives individual attention.
Do you offer daycare and activities?
Yes, daycare is available in the mornings from 8.00 am and in the evening until 6.30pm for kindergarten and elementary school pupils. A wide range of extra-curricular activities (tennis, art, music, etc.) are also available after school.
Is the IB recognised by the French state?
Absolutely. The IB Diploma is recognized by the French State and highly valued by prestigious universities in France and abroad. 100% of our students go on to the university of their first choice (McGill, King's College, Prépas françaises, etc.).
