In the UK children normally start reception class when they are four years old. This means they turn five during their reception class year. This is a time of significant change for many children and their families.
If your child is born between 1 September 2014 and 31 August 2015 they would normally start reception class in September 2019. You must apply before 15 January 2019 even if you wish to delay or defer their start in reception.
