How to read these numbers
Wales doesn’t publish school-level results
- Not published in Wales. England publishes each school’s Key Stage 2 and GCSE results; Wales publishes no school-level results tables comparable with them. Estyn inspects Welsh schools and publishes a report on each, without a one-word judgement. So we list Trethomas’s schools and leave the School Grade out, rather than grade Welsh towns on a different measure.
- Estyn. Each school’s latest inspection report is on Estyn’s website: search by the school’s name. estyn.gov.wales ↗
