Parents are finding out today if their children have been given their first choice of primary school.
Thousands of new places have been created to meet a growing demand.
Today is the first national "offer day" when admissions have been coordinated by all 152 local authorities in England at the same time.
An increase in birth rate combined with an influx of migrants in some areas has driven an increase in the number of four and five-year-olds starting school.
There is concern that more children will miss out on their first choice place because of this.
The Department of Education has given local authorities £5 billion to create more primary school places, with a further £2.35 billion made available between 2015 and 2017.
