How GPA is Calculated in Ontario

Ontario high schools use a 4.0 GPA scale for college applications. The conversion from percentage marks to GPA points is as follows:

GPA Calculation Formula:

GPA = (Sum of all course GPA points) / (Number of courses)

Each course mark is converted to GPA points using the table below.

The Ontario Ministry of Education provides the official conversion table for marks to GPA points. This table is used by all Ontario high schools for college applications.

Mark to GPA Conversion Table

The following table shows how percentage marks are converted to GPA points in Ontario:

Percentage Range	GPA Points
90-100%	4.0
80-89%	3.0
70-79%	2.0
60-69%	1.0
Below 60%	0.0

Note: Some high schools may use slightly different conversion tables, but this is the standard used by most Ontario schools for college applications.

Worked Example

Let's calculate the GPA for a student who took 5 courses with the following marks:

English: 85% (3.0 GPA)
Math: 72% (2.0 GPA)
Science: 92% (4.0 GPA)
History: 68% (1.0 GPA)
French: 88% (3.0 GPA)

Calculation:

Total GPA points = 3.0 + 2.0 + 4.0 + 1.0 + 3.0 = 13.0

Number of courses = 5

GPA = 13.0 / 5 = 2.6

The student's GPA for this term would be 2.6.
