Plain-language summary · AI-assisted
Two sets of temporary, time-limited provisions have been formally struck from the class-size regulation. First, a circumstance that allowed JK/kindergarten classes to exceed the 29-pupil limit when purpose-built accommodation was unavailable (which applied only through the 2021–2022 school year) has been revoked. Second, a table of board-specific maximum average class sizes for grades 4–8 that applied only in the 2017–2018 and 2018–2019 school years has been removed. Neither provision had any ongoing practical effect, so day-to-day class-size rules for school boards are unchanged. Boards should confirm their compliance planning references the current standing limits only: a 26-pupil average and a 29-pupil hard limit (with a 32-pupil cap in narrow circumstances) for JK/K classes, and a 24.50 average for grades 4–8 classes.
