Students in grades SK, 1 and 2 participate annually in the Gates-MacGinitie standardized reading tests in May/June. This allows HMDCS to carefully chart their reading progress for the primary years.

Students in grades 3 - 8 participate every other year in the Canadian Tests of Basic Skills (CTBS) in early October. (We will participate again in October 2008.) It measures a student's knowledge and is used as a tool to analyze program weaknesses and student progress. It shows national percentile comparisons as well as OACS (Ontario Alliance of Christian Schools) comparisons. Parents are informed of their child(ren)'s progress in a report sent home.

Grade 7 and 8 students also participate in the annual Gauss Math Contest.
