Estyn inspection
This inspection took place under Estyn's previous framework, which gave summative grades. Those grades are published in the report itself, which OfferDay links to in full rather than reproducing.
School characteristics
From the Welsh Government school census, latest 3 years.
Wales does not publish school-level exam results under an open licence, so OfferDay does not show attainment figures for Welsh schools. Estyn reports on each school, and the Welsh Government publishes results at national and local-authority level.
