Is "standard" an archaic synonym for an athletic team or club?

This was passed along to me (native US speaker) by a non-native speaker.

A school in the UK asks for the following details…

Games

Teams and Standards

Extra-curricular Activities

…in their application form for prospective students.

Our best guess was that "standard" was a synonym for "team" in British English, but I decided to research it.

Couldn’t find a definition for "standard" in Wiktionary, Cambridge or MacMillan dictionaries that fit this context.

Web search with exact-match terms "teams and standards" didn’t turn up anything conclusive.

Perhaps the obvious conclusion is they meant "ability", in which case they’d be asking for "teams and playing standards". In that case, the phrasing is unfamiliar to us.

The school is in Oxfordshire, on the off-chance regional dialects need to be considered.
