Bishops Cannings is very good and can get quite oversubscribed, especially with the schools on that side of Devizes not being as good, All Cannings, Rowde and Chriton also have a great reputations. Heddington and Cherhill are more local to Calne so I don't know them that well. They are closer to Calne where, if a church school isn't an issue, then St Edmunds has a great reputation.
