School boundaries this address is inside
Where these boundaries come from, and what they are worth
A school boundary is the area a board draws around a school. An address inside several of them is normal — boards publish a separate boundary per program, so regular track, French immersion and specialist programs each have their own.
York Region. Published by the York Region District School Board’s planning department, with the date the board approved each boundary shown above. A boundary approved years ago is still the current one until the board redraws it, but the older the date, the more worth confirming.
Homula cannot tell you which school a child will attend. Boards move boundaries, hold students at capacity, cap programs and grant exceptions, and none of that is in any published file. The board is the only authority: YRDSB school locator.

How the rating is calculated
EQAO — Ontario’s testing agency — publishes, for each school, the percentage of students meeting the provincial standard in Grade 3 and Grade 6 reading, writing and mathematics. The rating is the average of those percentages divided by ten. A school where 72% of students met the standard rates 7.2 out of 10.
Nothing is weighted or adjusted, and schools are not ranked against each other. Where EQAO withholds a result to protect the privacy of a small group of students, that measure is left out rather than counted as zero — so a rating built on fewer than six measures says so.
What it does not measure. It is one year of standardised testing in three subjects. It says nothing about teaching, programs, or whether a school suits a particular child, and it tracks neighbourhood household income closely enough that it partly measures the neighbourhood rather than the school. Treat it as one figure among many.
