Top-quality school form (4-5)

Ross

I believe the answer is:

high-class

'top-quality' is the definition.
(of the best quality or class)

'school form' is the wordplay.
'school' becomes 'high' (high school is a kind of school).
'form' becomes 'class' (synonyms).
'high'+'class'='HIGH-CLASS'

(Other definitions for high-class that I've seen before include "Superior" , "Posh" .)

I've seen this clue in The Times.
