Ungraded inspection: no current grade
Ofsted's most recent visit was an ungraded inspection; its outcome was “Standards maintained”. Since September 2024 these outcomes no longer confirm a named grade. No graded inspection appears in Ofsted's records for this school since 2015 either, so SchoolFacts shows no grade rather than guessing. Any earlier grade is on the school's Ofsted report page.

Source: DfE performance tables 2024/2025 · what “suppressed” means National averages are not shown here. The England figures are dominated by mainstream schools, and pupils at a special school are working towards outcomes those measures were not designed to capture, so the comparison would mislead more than it tells you.
