Quick answer
Sutton has five grammar schools in a compact South London cluster. The main split is simple: three boys' schools, two girls' schools, and shared SET context for several routes before school-specific details take over.
- Wilson's, Sutton Grammar and Wallington County Grammar form the boys' route.
- Nonsuch and Wallington High form the girls' route.
- Travel across Sutton and the second-stage/admissions detail can separate schools that look close on a map.
Who this guide helps
-
Families starting with Sutton but not yet sure how the five schools split
The guide separates the boys' and girls' routes before results or rankings enter the conversation.
-
Families comparing boys' and girls' routes separately
Sutton is clearer when Wilson's, Sutton Grammar and Wallington County are not mixed into the same comparison as Nonsuch and Wallington High.
-
Families checking whether a nearby non-Sutton option still belongs in the search
A nearby borough can be worth comparing, but only when the journey and admissions route are still credible.
How Sutton usually narrows
Boys' route
- Usually includes
- Wilson's School, Sutton Grammar School, and Wallington County Grammar School
- Best when
- Your active shortlist is focused on boys' schools within the Sutton cluster
- Check first
- Which combination of journey, admissions reality, and school fit still works from home
Girls' route
- Usually includes
- Nonsuch High School for Girls and Wallington High School for Girls
- Best when
- You are comparing a girls' shortlist inside or close to the Sutton cluster
- Check first
- Whether both schools still belong in one final offer-day choice set
Sutton plus one nearby stretch option
- Usually includes
- A mostly Sutton shortlist with one school outside the immediate cluster
- Best when
- There is a clear travel or family reason to compare that extra option
- Check first
- Whether this is still one practical shortlist rather than two different routes
The school pages most parents open first are Wilson’s School, Sutton Grammar School, Wallington County Grammar School, Nonsuch High School for Girls, and Wallington High School for Girls.
What to answer before you compare results
-
Which Sutton schools are practical to reach every day?
Travel is often the fastest way to stop the shortlist becoming wider than it should be.
-
Is this a boys-only or girls-only route?
That usually clarifies the comparison set immediately.
-
Are we comparing only within Sutton, or against another nearby cluster as well?
If another cluster is involved, make sure it belongs in the same real family decision.
-
Which schools would we actually choose between on offer day?
If that answer is still vague, the shortlist probably needs more narrowing before results become useful.
