The maximum class size permitted in the preschool is 25 and 15 in playgroups. When a class reaches 25 students, the grade is either closed to new enrollments, another section is created, or additional personnel are provided. Therefore we follow the international norm of adult child ratio in preschool. The adult and child ratio in PG (2yrs. Old) is 2:15, 2: 20 in Foundation(3yrs old) and 2:25 in Preschool (4 and 5 yrs old).
