About The Costello School

The Costello School in Basingstoke was rated Good overall by Ofsted in its most recent inspection in 2021, with personal development judged Outstanding. The school’s Progress 8 score of -0.03 is the most informative exam metric available, and it tells a clear story: pupils here achieve almost exactly the national average progress, and they significantly outperform the Hampshire local authority average of -0.17. This means the typical Costello pupil leaves Year 11 with results broadly in line with what you’d expect from any student in England, while doing notably better than the average secondary school in its own county. The Attainment 8 score of 46.3 provides a solid baseline, and 66.1% of pupils secured a grade 4 or above in both English and maths, with 44.5% reaching the higher grade 5 threshold. The school does not have a sixth form, so students move on after Year 11.
