They don't allow all the Grade 3 students to take the test. Usually the test is given by a psychologist, so it is going to spend hundreds of $$ for one student. The students in Seneca Hill gifted program are from many schools surrounding Seneca Hill( I guess all of the North York schools belong to Don Valley East). After graduation from Grade 6, they automatically go to Zion high, there is a gifted program for junior high, then finally all of the gifted students in North York go to Don Mills collegiate institute gifted program for high school until they go to the university.
