But sometimes the premium you pay to get near a school might not be worth it - perhaps the school doesn't really perform as well as you think it does, or maybe the cost of living that bit closer to it is way higher than the local average.
So how can you work out where to get the most bang for your buck when trying to find the best value property for your children's education?
We've crunched the Land Registry's figures for houses bought so far this year and averaged it across postcode districts to find the average cost of a property within the catchment radius of every school in the country.
The X-axis shows the percentage of pupils getting at least five A-C grades including English and maths. The Y-axis shows the percentage difference between the school's postcode and the local authority. The cost of attendance is not considered.
