Pupil–teacher ratio: not published — independent schools aren’t in the DfE workforce census, and filed accounts don’t separate teaching staff.
Capital trend: only one year of capital spend is on record, so a multi-year under-investment signal can’t be computed yet.
Computed 2026-06-20 · pipeline ct-derived-1.0.0. Indicators, not verdicts — each is traceable to its source.
