Medium-sized school — the SALSA score is reasonably stable but individual cohorts can have an impact.

SALSA measures relative performance — not absolute school quality. The model explains approx. 53% of variation; the rest depends on factors like leadership, teaching, resources and pupil selection not captured by the model. Independent schools with selective admissions may show higher SALSA scores without necessarily better teaching.
