Eton College, one of the most important collegiate churches founded in England in Later Middle Ages (prime function to pray for Henry VI - education secondary) still has a provost (pronounced pro-vo) as head of its governing body. However, its closest analogies, Windsor and Winchester, have, respectively, a Dean and a warden.
Eton's sister institution, King's College Cambridge, also has a Provost. M.R. James was, of course, successively both.
(Winchester's sister institution, New College Oxford [recte The College of St Mary of Winchester at Oxford - but called "New College" to distinguish it from the other St Mary's College] also has a Warden. Other titles for college heads are Master [Mistress], Dean, President.)
