When deciding what primary school to send your child too, there are a number of factors to take in to account. Often, for parents, location has to be a major factor. If there is a school very local to you, you may wish to send your child there because it is convenient and perhaps because their friends from nursey will be attending. Although this may wish to be taken in to account, you should not base your decision on this alone.
Looking at the league tables for a school will give you an idea of how the pupils are performing overall. It will tell you what percentage of children are achieving the expect levels, above the expected levels and below the expected levels for children of a similar age.
When looking at these levels it is often important to try and see what level the children were when they first started the school to see how much progress they have made rather than what level they are at as this will show how good the teaching is at the school.
