For a good snapshot of BC Elementary School Academic Performance find the link below to the annual Fraser Institute Report.
This report relies on standardized government testing in Grades 4 & 7 across British Columbia. The Fraser Report is very helpful when looking at schools in the Greater Vancouver Area in particular but uses a narrow approach not providing a full picture of the merits of each school. Additionally special school attributes are not considered. When relocating it is important to keep an open mind about the best fit for each child. I know my own children have surprised me tremendously during our relocation!
