The recent contract settlement reduced class sizes at most grade levels and in most schools. The newly negotiated limits may be found in the table below. It is important to note that class sizes in schools with fewer than 6.5% of students on IEPs are somewhat larger.

In Bilingual, ESL, and SEI classes, there can be no more than 20 students at any grade level, or the lower of the limit in the above table or 25 if a paraprofessional is provided.

In elementary schools where there is only one regular education class in a grade level, the above maxima may be exceeded by one or two students. Similarly, in secondary schools where there is a singular regular education course offering (for instance, only a single section of French 4, or AP Physics, etc.), the maxima may be exceeded by one or two students.
