The exact dates on which ISEE tests are administered vary between offices authorized to give the test, but most testing centers offer tests at least once a month between August and May. As of 2015, the majority of tests take place at regular intervals throughout the school year.
The ISEE is an entrance exam for independent schools. It is used both within the United States and internationally to place students in independent schools. The test is designed for students between the ages of two and 12, and is designed to test logical reasoning skills as well as knowledge of a variety of academic subjects.
