  • A non-programmable, non-graphing, scientific calculator
  • A scanner, smart phone camera, or similar device to upload handwritten or hand-drawn work
  • A front-facing camera on a desktop, laptop, or mobile device to allow for proctoring over the internet
  • Internet access and a modern standards-compliant web browser

Assessment & Evaluation

The assessment and evaluation strategies of our school follows the Ministry of Education's Growing Success document. Growing Success articulates the vision the Ministry has for the purpose and structure of assessment and evaluation techniques.
Assessments help to monitor student progression and provide reflection and feedback. Evaluation is the process of judging the quality of student work in relation to the achievement chart categories and criteria, and assigning a percentage grade to represent that quality. Evaluation is based on gathering evidence of student achievement through:

  • Products
  • Observations
  • Conversations

Weighting of the Categories of Achievement

Knowledge & Understanding Thinking Communication Application
30% 20% 20% 30%

The Final Grade

  • The evaluation for this course is based on the student's achievement of curriculum expectations and the demonstrated skills required for effective learning. The final percentage grade represents the quality of the student's overall achievement of the expectations for the course and reflects the corresponding level of achievement as described in the achievement chart for the discipline.

Course withdrawal and repeats

You can safely enroll and try this course. Since this is a Grade 9/10 course, you can drop this course at any time, without any academic penalty.

You can also retake Grade 9/10 courses as many times as you want. If you retake and achieve a higher mark, this higher mark replaces your existing mark on your transcript. If you retake and somehow do worse than before, then nothing changes: you retain your existing mark. The number of times you retake a course will not be revealed to others since this information does not appear on your transcript (this is unlike Grade 11/12 courses, where each attempt if not withdrawn properly will be recorded on your transcript).

Ministry guidelines regarding course withdrawals and retakes

According to Ministry policies, grade 9 and grade 10 courses can be withdrawn at any time without any academic penalty. The grade 9 and 10 courses can also be repeated an unlimited number of times without any academic penalty. Grade 9 or 10 courses withdrawn are simply not recorded on the OST (it is as if you have never registered for the course). When students retake grade 9 or 10 courses, the highest mark is recorded on their OST, replacing the lower mark.

However, withdrawing from grade 11 or grade 12 courses without academic penalty must be done within 5 days of receiving the first report card. In this case, the mark will not be recorded on the OST. On the other hand, withdrawal from a grade 11 or grade 12 course after 5 days of receiving the first report card results in the following permanent record on the student’s OST: a "W" being entered in the "Credit" column of the OST along with the mark at the time of the withdrawal. If there are extraordinary circumstances relating to a student's withdrawal from a course, an "S" may be entered in the "Note" column on the OST.

Retaking grade 11 and grade 12 courses leads to permanent records of all repeats on the student’s OST, along with the marks of each attempt. Only one credit is earned if a course is retaken. An “R” is entered in the “Credit” column of the OST for the repeats with the lower mark.

It is therefore advised that students taking grade 11 and grade 12 courses be mindful of withdrawal deadlines pertaining to their enrollment, and do their best in the course if they have passed the withdrawal deadline.
