Student needing job that pays after end of school (7)
I believe the answer is:
learner
'student' is the definition.
(I've seen this before)
'job that pays after end of school' is the wordplay.
'job that pays' becomes 'earner' (term for a job which lets someone earn good money).
'after' is a charade indicator (letters next to each other).
'end of' indicates one should take the final letters.
The last letter of 'school' is 'l'.
'earner' put after 'l' is 'LEARNER'.
'needing' is the link.
(Other definitions for learner that I've seen before include "Student (of driving?)" , "One who studies" , "One with an L-plate" , "Tyro" , "Someone undergoing education" .)
