Small class size, excellent teachers, a high-quality curriculum and parent involvement all contribute to Alberta being one of the best learning systems in the world.
How class size is calculated
The Class Size Information System is available for calculating class size averages at the school and jurisdiction levels. Boards are required to use the Jurisdiction Report generated by the Class Size Information System to post their annual class size survey results in their Annual Education Results Report each year.
Class size funding
Class size funding is based on a per student grant. The Class Size Initiative funding formula focuses on:
- reducing class sizes in Kindergarten to Grade 3
- enhancing funding for specific Career and Technology Studies (CTS) courses to address safety and teacher/student ratios
Government does not specify a maximum class size. Schools and school boards are in the best position to determine classroom organization that supports parent and student educational choice.
The class size funding formula allocates funds based on a specific grade level or specific CTS courses. School jurisdictions have the flexibility to hire or retain teachers in any grade based on local needs. This approach allows a more strategic and flexible approach for local boards in their decision making.
Since the inception of the Class Size Initiative in 2004/2005, government has invested nearly $3.3 billion to enhance student learning.
The difference between Class Size Average and Student/Teacher Ratio
Student/teacher ratios measure the ratio of students to all professional staff that provide classroom services and support. Student/teacher ratio includes counsellors, teaching assistants, librarians, principals and central office staff.
Class size averages measure the actual number of students being taught by a certificated teacher in one classroom.
Class size averages are therefore typically higher than student/teacher ratios.
Report of the Auditor General – February 2018
The February 2018 Report of the Auditor General to Members of the Legislative Assembly (MLAs) highlighted topics of interest and importance to all Albertans, including an audit of the processes to manage the Class Size Initiative.
