Japari's classrooms are for the most part situated to the south of the school campus. Due to the specialised nature of our school, our class sizes are small. Grade 0 and 1 are kept to 10 or less, whereas Grade 2 - 7 will be limited to 15 in a class.

Japari normally carries two classes per Grade except for Grade 0 where there is one class. On occasion, three classes in a particular Grade is necessary due to demand.
