More Information

The Schools Address Book is a listing of all State Primary, Secondary, Nursery, Special Schools and Education Support Centres in the county (Academies are included, although not maintained by HCC).

The GIS Dataset now includes those that are open, planned or have closed (starting from September 2012).
In *most* cases schools converting to Accademies will just have their Governance changed - although some have chosen to re-register with the DfE and have new numbers.
Schools re-opening as a different phase will be re-added as a new record - currently their HCC School number will be the same and so their GIS ID will be changed to end in a 2.
