The size of the school is limited by the capacity of the school buildings, which in turn, are limited by the size of the site. But, there is a larger question of “how big is too big” for a school educationally. There is no universal agreement about the numerical limits of small and large schools; however, research indicates that an effective size for an elementary school is in the range of 300-400 students and that 400-800 students is appropriate for a secondary school.
This research would consider these figures to be the upper limits. Our own experience indicates that most international schools fit within these ranges of enrollment. If larger enrollments are necessary, ISS can provide advice on how to develop a ”school within a school” educational program creating the more personal campus environment for students in a larger enrollment campus.
