The catchment area is a geographical area from which children may be afforded priority for admission to a particular school. A map of the school’s catchment area can be viewed on the school’s details page on the Hampshire County Council website.

The link 'School Catchment Finder in Hampshire' under 'External Web Links' will confirm if your house is in Thornden's catchment area. 

Following a decision of the Schools Adjudicator (ADA4117), the admission policy was revised, to give effect to that decision. Consequently, the catchment area boundary for the school has been adjusted to include the houses to the North and North East of Brownhill Road, that were previously in the catchment area of The Toynbee School. A map of the affected area can be found below.
