The SABIS® Educational System is highly academically-oriented without being highly selective. The criterion for acceptance in a class is academic attainment. Although age acts as a limiting factor, it is possible to find a three-year age range in the same class. In general, any student willing to learn is accepted.
There are no academic requirements for acceptance into Kindergarten (3 to 5 years of age). Prospective students at these levels are interviewed; they must be toilet-trained and able to speak and follow simple instructions.
All other prospective students take diagnostic tests in the core subjects. These tests help to determine if the students have attained the minimum expected standard for each subject. The school then makes final placement decisions but can resort to the various strategies at its disposal to help bring a student to the required level. For example, there is the option of attending summer school or perhaps extra classes in a subject. Special academic support is taken very seriously by the school.
