(September 2026 Mandatory Assessment and Evaluation Requirements)


Achievement Categories (GS pages 16-18 and 24-25)

The achievement chart identifies four categories of knowledge and skills: Knowledge and Understanding, Thinking, Communication and Application. This chart serves as a standard province-wide guide, enabling teachers to make consistent judgments about student work based on clear performance standards and a body of evidence collected over time. 


The categories of knowledge and skills are:

Knowledge and Understanding (KU) – Subject – specific content acquired in each grade/course (knowledge) and the comprehension of its meaning and significance (understanding).

Thinking (T) – The use of critical and creative thinking skills and/or processes.

Communication (COM) – The conveying of meaning through various forms.

Application (AP) – The use of knowledge and skills to make connections within and between various contexts.


A final grade is recorded for every course, and a credit is granted and recorded for every course in which the student’s grade is 50 per cent or higher. The final grade for each course in Grades 9 to 12 will be determined as follows:

Sixty-five percent of the grade will be based on evaluations conducted throughout the course. This portion of the grade should reflect the student’s most consistent level of achievement throughout the course, although special consideration should be given to more recent evidence of achievement.

Twenty or Twenty-five percent for final evaluation. 

Breakdown of Final Evaluations (Exams vs. Culminating Tasks)


The 20% (Grades 9–10) or 25% (Grades 11–12) final evaluation is further broken down by subject area. Beginning in 2026, written exams are mandatory for most secondary courses and must occur during the designated exam period.


What “counts” in the 65% grade? 

Grades 9 through 12 are now based on classroom work completed throughout the course. This portion consists of evidence that the student has demonstrated achievement of the overall expectations outlined in the curriculum policy document for the subject.

Students must be provided with opportunities to practice and receive timely feedback before their learning is evaluated. Formative assessments, such as self- and peer assessments, are used to provide constructive feedback and should not be included as part of the evaluated 65% classroom work grade; only formal evaluations are included in the student’s reported grade.

Note: Assessments should not be administered by supply teachers or on-call teachers. Classroom teachers must be present when an assessment is administered to support student learning and the demonstration of knowledge and skills.


Mandatory Final Evaluations (20%-25%) 

The purpose of the final evaluation is to provide students with an opportunity to demonstrate their learning of the overall expectations of the course. Most secondary courses now require written exams to be administered during the designated exam period.

Core Subjects (English, Math, Science): Require a full 20% written exam in Grades 9–10 and a 25% written exam in Grades 11–12.

EQAO Grade 9 Math: This assessment now counts as the written exam and must be weighted at exactly 20% of the final mark.

Other Subjects (Arts, Tech, Business, etc.): Typically require a 10% written exam combined with a 10% or 15% culminating task.

The final evaluation must include questions from all four achievement categories using the same weighting assigned for the 65% classroom work evaluations. No new content or skills should be introduced during this time; students are demonstrating knowledge and skills already learned. Marks from any evaluations held prior to the formal examination period are included in the 65% classroom work grade.

Marks from any evaluations held in the middle of the semester or prior to the examination period are always to be included in the students’ 65% grade and are not included as any part of the final 20%-25% evaluation.  Final 20-25% of the course should start no earlier than the last 4-6 weeks of the course.
