Student to Teacher Ratio — methodology

What this metric measures

Full-time equivalent school students per full-time equivalent teaching staff, across all affiliations and school levels.

Why it matters: Class size shapes how much individual attention students receive. The ratio is the standard national measure of teaching capacity relative to enrolments.
