Class Size and Composition
In 2002, the provincial government passed legislation that removed all learning conditions, including all class size and class composition limits, from the collective agreements. In addition, the legislation removed all guarantees of services provided
by specialist teachers such as librarians, counsellors, learning assistance and ESL teachers. All guaranteed supports for special needs students were also removed.
Following the decision of the Supreme Court Of Canada in November of 2016, government was required to reinstate the class size limits, class composition provisions and staffing ratios that were unconstitutionally removed in 2002. Effective for the commencement
of the 2017-18 school year, the limits for primary classes are 20 students for Kindergarten and 22 students for Grades 1 to 3. Class composition provisions and class size limits for intermediate and secondary classes vary from district to district, as specified
in local collective agreements.

What's in the research?
Diane Whitmore Schanzenbach of Northwestern University undertook a review of the literature and
found that class size does indeed matter. Based on the research as a whole, Schanzenbach makes the following
policy recommendations in her 2014 report:
- "Class size is an important determinant of student outcomes, and one that can be directly determined by policy. All else being equal, increasing class sizes will harm student outcomes.
- The evidence suggests that increasing class sizes will harm not only children's test scores in the short run, but also their long-run human capital formation. Money saved today by increasing class sizes will result in more substantial social and educational
costs in the future.
- The payoff from class-size reduction is greater for low-income and minority children, while any increases in class size will likely be most harmful to these populations.
- Policymakers should carefully weigh the efficacy of class-size policy against other potential uses of funds. While lower class size has a demonstrable cost, it may prove the more cost-effective policy overall." (10)
