One shared test for all four Bexley grammar schools, assessing three areas: 1. Verbal ability and English comprehension. 2. Numerical reasoning (maths-based). 3. Non-verbal reasoning. Multiple-choice, age-standardised. One sitting covers all four schools. Registration is unusually early — historically 1-31 March of Year 5 (most areas close in June), with the test in the first half of September of Year 6 (primary-school test centres first, grammar-school test centres a few days later). Missing the March window means missing the main round entirely, so families considering Bexley should diarise it well ahead.

Of the 218-student 2019/20 leaver cohort, sustaining a higher-education destination the following year. This is the last cohort the Department for Education published with an Oxbridge/Russell Group breakdown — these categories were discontinued as official accountability measures after this release, so a more recent figure does not exist.

Median price for the school's electoral ward, year ending March 2023 — a neighbourhood-level indicator, not the school's actual admissions catchment (catchments are often smaller than a ward or span parts of several).
