In 2026 the furthest child offered a place lived 1.50 miles from the school in a straight line, according to the council's published allocation figures; the distance changes every year with demand. Overall pupil absence was 4.4%. There are about 25.0 pupils per teacher. Its intake is relatively advantaged, with around 7% of pupils eligible for free school meals in the last six years versus about 24% nationally. When comparing schools, it is still worth visiting in person to see whether the atmosphere and approach suit your child.
