Correct religious education class (6)

Ross

I believe the answer is:

reform

'correct' is the definition.
(thesaurus)

'religious education class' is the wordplay.
'religious education' becomes 'RE' (abbreviation).
'class' becomes 'form' (synonyms).
're'+'form'='REFORM'

(Other definitions for reform that I've seen before include "Change one's ways (for the better?)" , "Go straight" , "Mend one's ways" , "Removal of abuses" , "Correct(ion of) abuses" .)

I've seen this clue in The Telegraph.
