Student got educated (7)
I believe the answer is:
learned
'educated' is the definition.
('learned' can be similar in meaning to 'educated')
'student got' is the wordplay.
'student' becomes 'l' (as in L-plates for learner drivers).
'got' becomes 'earned' (earning is a kind of getting).
'l'+'earned'='LEARNED'
(Other definitions for learned that I've seen before include "a word defining friend from Chambers?" , "Well-educated" , "Literati" , "Knowledgeable - scholarly" , "Erudite, knowledgeable" .)
