College schoolboy since 1440 (7)

I believe the answer is:

etonian

(Other definitions for etonian that I've seen before include "Public school pupil" , "Public school boy" , "Relating to one particular school" , "One educated at famous public school" , "Pupil at posh English school" .)

I've seen this clue in The Guardian.
