All courses for students in Kindergarten on up are clearly structured to enable students and teachers to know precisely what should be learned. The whole class is taught together, using the SABIS^® Point System™. The key concepts of a lesson are listed. Each of these is taught interactively, alternating oral work, individual written work, and group checking. Class time is utilized for building a solid foundation of knowledge through interacting, analyzing, forming and expressing opinions, and engaging in effective discussions. These discussions are based on critical thinking and logical reasoning.
