Standing over the pupil, a girl (4)

I believe the answer is:

nola

'girl' is the definition.

'standing over the pupil a' is the wordplay.
'standing' says the letters should be written in reverse (in a down clue, letters stand up).
'over' becomes 'on' (physically on top of).
'the pupil' becomes 'L' (as in a learner driver with L-plates on their car).
'on' in reverse letter order is 'no'.
'no'+'l'+'a'='NOLA'

I've seen this clue in the Evening Standard.
