About this data source & caveats
Progress 8 is not published for 2024–2025. This year group missed their key stage 2 tests in 2020, so there is no baseline to measure progress from.
Attendance comparisons are pupil-weighted averages we calculate from every school’s published absence figure — the DfE absence file has no local authority or England rows of its own.
We show the headline measures only. Threshold and curriculum-policy figures — grade 4+ in English and maths, EBacc entry and points, the per-subject key stage 2 breakdown, academic and applied splits at 16 to 18 — reflect admissions and curriculum choices more than school quality, so they are left to GOV.UK. Progress measures matter most because they compare pupils with others who started at the same level; attainment on its own largely tracks a school’s intake.
Figures are the Department for Education’s official published results for Watford Grammar School for Boys. Results are suppressed where too few pupils were entered. England figures are the average for state-funded schools. “Top x%” is this school’s position among all schools in England with a published figure for that measure — the DfE does not publish league table rankings.

Location & catchment area
Indicative only. This is a nearest-school (Voronoi) estimate — the area closer to Watford Grammar School for Boys than to any other secondary school. Real admissions depend on the school’s own policy (straight-line distance, siblings, faith, feeder schools and available places) and change each year. Always confirm with the school and local authority admissions team.
