The criterion for acceptance into the school is a willingness to put in the effort to achieve full potential, not high 'innate' ability. Placement into classes is determined by academic attainment, with age acting as a limiting factor. Students applying to enter Grade 2 and above must take diagnostic tests to determine placement.
Students who are found to be behind academically are rarely refused. Instead, they are offered, at an extra cost, one of several different solutions, depending on their academic needs. These may be:
Special Lessons: A student found to be weak in one subject attends extra periods in that subject until the level of the class is reached.
Full-Special Classes: Students are given accelerated programs intended to prepare them to join the regular classes. In many cases, Full-Special students have done the work of two or more scholastic years in one.
