How this page ranks schools
Schools are ordered by the published share of students achieving AAB or better at A level.
We compare schools here using one published sixth-form measure:
What To Keep In Mind
This page stays strictly sixth-form focused, so GCSE data is not used in the order.
A school needs published A-level results to receive a rank on this page.

Keep narrowing
Strong post-16 outcomes can narrow a long list quickly. Final choices usually come down to admissions reality, travel, school fit, and how the remaining sixth forms compare once they are close together.

Useful when published Key Stage 4 performance matters more than sixth-form outcomes in the first pass.

Before you shortlist
This page is for parents who want a sixth-form-first view. It uses one published A-level measure, so it can help you spot the schools with the strongest post-16 academic outcomes before travel, admissions, and school fit start reshaping the shortlist.
A-level results matter, but they are still only one slice of the picture. Use this ranking to narrow quickly, then open school pages and compare the schools that still look realistic for your child and your family.
FAQ
This ranking uses the published share of students achieving AAB or better at A level.
The GCSE page stays focused on Key Stage 4 measures. This page is sixth-form only, so it is more useful when post-16 academic outcomes matter most.
Not by itself. A-level strength is useful, but it does not tell you about admissions, travel, subjects offered, or whether a school feels right for your child.
Open the school pages and compare the shortlist properly so you can bring in sixth-form detail, admissions reality, travel time, and school fit.
