AFAIK the only statutory policies that must be reviewed annually are Performance Management and Pay, and if you are your own admissions authority, Admissions Policy. Additionally GB Committees - membership and Terms of Reference - and any other GB delegations (although these aren't strictly speaking policies). Additionally you might find that your LA financial procedures rules require you to review some finance policies annually, which in effect makes them compulsory. My LA requires annual review of Charging and Remissions Policy and Lettings Policy - why only those two I've no idea! Safeguarding Policy isn't required by law to be reviewed annually, although as Ofsted appear to think that annual review is expected practice most GBs treat it as if annual review were compulsory. It would be nice if DfE published a handy list of annually renewable polices but they don't.
