How have we plotted this heat map?
This School Guide heat map has been plotted using official pupil data taken from the last School Census. We calculate a likelihood of admission to a school from a given area based on this historical pupil data. Please see our methodology below.
Heat maps provide a useful indicator of general catchment areas but are not the same as a catchment area map published by the local authority. We are in the process of collecting this data and creating actual catchment maps for School Guide. Catchment maps are based on geographical admissions criteria and show actual cut-off distances and pre-defined catchment areas.

Methodology of a School Guide heat map
This School Guide heat map has been plotted using official school pupil data taken from the Pupil Level Annual School Census collected by the Welsh Government. The data tells us where pupils lived at the time of the last Pupil Census (released annually in July). We calculate a likelihood of being admitted to a school from a given area based on this historical data. Areas with a high concentration of pupils successfully admitted to the school are mapped as red (‘Very Likely’), quite concentrated (‘Quite Likely) and less concentrated (‘Less Likely’). This gives a good indication of the area a pupil would need to have lived in to be accepted to the school at the time of the last available data.
Our heat maps use groups of postcodes, not individual postcodes, and have naturally soft edges. They may mirror circular catchment shapes but do not show actual cut-off distances. All pupils are included in the mapping (i.e. children with sibling(s) already at the school, high priority pupils and selective and/or religious admissions) but we may have removed statistical ‘outliers’ with more remote postcodes that do not reflect majority admissions. Small clusters of pupils in rural areas of Wales may not be represented in the data.
Living at a postcode that returns a ‘Very Likely’ rating based on historical pupil data does not guarantee admission to a current or future intake and vice versa for a ‘Not Likely’ rating. A pupil’s location always needs to be considered alongside individual school admissions criteria (e.g. faith schools require pupils to satisfy religious criteria).
School Guide recommends you use the Local Authority link provided on the individual school page (click on The Data tab, above), if you require exact catchment information or contact the school directly (click on The Data tab, above) for individual admissions criteria.
