Achievement Levels
Here is a link to the Ontario Achievement Levels from the Ministry of Education. On page 14, if you look at Math, the expectations are separated into Knowledge and Understanding, Thinking, Communication, and Application.
On students’ tests, I separate their marks into Understanding (which encompasses Knowledge and Understanding and Thinking), Communication, and Problem Solving (the name we use for Application).
I hope this helps you to understand more specifically where your child can improve. If you have any questions, please send a note in your child’s agenda.
