Smaller class sizes? Find out with the class-size tracker

The Ontario government has lowered class sizes in the primary grades*. See the class sizes for your school, your school board and all of Ontario.

Why have we done this?

Students in smaller classes get more attention, do better and are more likely to succeed in high school and beyond.

How are we doing?

Large primary classes* have been phased out. Since 2008-09, we have maintained small class sizes across the province. This is still true in 2016-17:

  • 100% of primary classes* have 23 or fewer students this year compared to just 64% in 2003-04.
  • 90% of primary classes* have 20 or fewer students this year compared to 31% in 2003-04.
Primary classes* are getting smaller



  • Primary class size percentages have been rounded.
  • Totals may not add up due to rounding.
  • The government's full-day kindergarten (FDK) program is not included in primary class size calculations. Classes under the FDK program differ from other primary classes by having two educators - one teacher and one early childhood educator - in the classroom. In some cases where an FDK class has 15 students or fewer, only a teacher is required.
