Functioning of the Jardin des Particules

Children join the School from the age of 4 and begin their compulsory education according to the 1P / 2P curriculum of the Plan d'Etudes Romand (PER).

We place children at the centre of the educational process and take into account the multicultural and multilingual diversity of our environment.

Although we mainly follow the Plan d'Etudes Romand (PER), we adapt this as necessary to best prepare and meet the needs of our children who come from around the world, sometimes for only a short period.

Your children begin their schooling and learn their job as pupils: They are at the heart of their education thanks to the provisions of the Swiss Plan d'Etudes Romand in five areas:

  • Languages (French, English awareness)
  • Mathematics and Natural Sciences
  • Humanities and Social Sciences
  • Arts
  • Body and movement.

Like little scientists, children are placed at the centre of their experiences and learning.

The different educational philosophies that we follow—Montessori, Reggio Emilia, flexible class—help and facilitate the learning of concepts for each child, because each child is unique.

English awareness sessions are given in small groups on four afternoons per week. Swimming sessions are held on Wednesday afternoons.

The school is open Monday to Friday from 8 a.m. to 6 p.m. and a canteen service is available upon registration.

Children develop their self-confidence and curiosity in a stimulating yet peaceful environment.

Children leaving the 2P class will have acquired the necessary mastery of French, the concepts and skills required by the PER of the Swiss Department of Public Instruction, and will be ready to continue their education in public or private schools whether in Switzerland or in France.

In the Swiss system, children are assigned to a year group according to their age on July 31st. For the French system, assignment is according to the age on December 31st.
