Entry evaluation for students

From Grade 1 all students entering ISF take a placement test to determine their grade level, as school systems around the world vary. This can be arranged either online or in person with your visit.

Brief description of entry evaluation required

There are no academic requirements for acceptance into Kindergarten, although students applying to Kindergarten must turn 3 by June 30 in the year they will enter the program. They must also be able to speak and follow simple instructions as well as be toilet trained.

Candidates for grades 1–2 have a meeting with the Primary School Academic Coordinator, who also meets with the parents of each prospective student.

Students seeking entry to all other grades (3-12) take diagnostics tests in English and mathematics before entry. These diagnostic tests help ISF to determine the appropriate grades for each student and the correct level within each grade. For instance, in certain grades ISF may have four levels of English and German, two levels of mathematics, and several levels of French and Spanish. Therefore, it is vital that ISF places each student correctly, so that he or she is able to progress and learn.

The results of the diagnostic tests are discussed with parents before the final grade placement is made by the school.
