This map shows 'catchment areas' for a selection of primary schools in the London Borough of Waltham Forest. There a number of reasons why the map may be inaccurate (see the notes below) so it shouldn't be relied upon as a guide to whether any application would be successful.
The true catchment area is not a circle; a distance is identified as the furthest distance under which a pupil was accepted to the school under the 'distance' criteria. Pupils are also admitted under separate criteria - such as Special Needs, or the presence of a sibling in the school - in practice some of these pupils might live further away. For some schools, membership of a religious community is also an entry criterion.
The map allows some simple exploration to made of extent to which 'parental choice' is inequitable or illusory. In some areas, a prospective student will have a choice of more schools than in other places.
Optional layers are enabled via the layer control at the top right of the map.
