Grade 9 Math Course Enrollment by Type in Ontario Boards

Ontario public and Catholic school board-level data tracks Grade 9 Math course enrollment by type (academic, applied, locally developed) for each academic year. The Government of Ontario collects this data via the Ontario School Information System (OnSIS), with the dataset last updated in March 2026. It includes counts and percentages of students, though totals exclude private schools and certain specialized programs.

Use Cases

• Analyze trends in academic_year and course_type to study shifts in student enrollment between academic and applied math streams.
• Compare percentage_of_students across board_name to identify regional disparities in access to different course types.
• Use number_of_students and course_grade to calculate cohort sizes and participation rates for longitudinal studies.
• Investigate the prevalence of locally_developed course enrollment relative to standard academic/applied tracks by board_number.

Strengths

• Data is collected via a standardized provincial system (OnSIS), ensuring consistent reporting methodology.
• Includes both counts (number_of_students) and derived metrics (percentage_of_students) for analysis.
• Covers multiple academic years for time-series analysis of enrollment trends.

Limitations

• Data excludes private schools and several other educational settings, limiting comprehensiveness for the full student population.
• Small counts (less than 10 students) are suppressed for privacy, creating data gaps for small cohorts or rare course types.
• Enrolment totals are rounded to the nearest five, reducing precision for small-scale analysis.
