Established clique at university (3,2)

I believe the answer is:

set up

'established' is the definition.
('set up' can be similar in meaning to 'established')

'clique at university' is the wordplay.
'clique' becomes 'set' (I've seen this before).
'at university' becomes 'up'.
'set'+'up'='SET-UP'

(Other definitions for set up that I've seen before include "Established" , "advantageous position at Wimbledon?" , "Conspiracy" , "Exalt - arrange - begin" , "Assemble - design - establish" .)

I've seen this clue in The Telegraph.
