Turning cheek, raised student (5)
I believe the answer is:
pupil
'student' is the definition.
(pupil can mean a student at a school)
'turning cheek raised' is the wordplay.
'turning' is a reversal indicator.
'cheek' becomes 'lip' (both can mean insolence or rudeness).
'raised' becomes 'up' (similar in meaning).
'lip'+'up'='lipup'
'lipup' backwards is 'PUPIL'.
(Other definitions for pupil that I've seen before include "Eye opening" , "one may see through!" , "One studying" , "Trainee barrister" , "Dark centre of the eye" .)
