Ontario Secondary School Course Enrolment Statistics

Enrolment numbers track students in grades 9 to 12 across ministry-defined secondary school courses in Ontario. Data is reported by public and Catholic schools to the Ontario School Information System. Privacy protection suppresses counts below 10 students, and numbers from 2018-2019 onward are rounded to the nearest five.

Use Cases

• Analyze enrolment trends by course_code and grade to identify popular or declining subjects.
• Compare student counts across pathway_or_destination categories to assess vocational versus academic track interest.
• Track annual changes in enrolment numbers for specific course_description fields to inform resource allocation.

Strengths

• Includes data from two major school types: public and Catholic.
• Privacy protocols suppress small counts below 10 students to protect confidentiality.

Limitations

• Enrolment counts are rounded to the nearest five starting 2018-2019, reducing precision.
• Students enrolled in a course more than once are counted each time, which may inflate unique student counts.
