Quentin regularly avoided academic institution (3)

I believe the answer is:

uni

'academic institution' is the definition.
(university)

'quentin regularly avoided' is the wordplay.
'regularly avoided' means one should take alternating letters.
The alternate letters of 'quentin' are 'UNI'.

(Other definitions for uni that I've seen before include "Number of colleges" , "Seat of learning" , "Where you can study" , "educational establishment" , "Short for university" .)

I've seen this clue in The Times.
