Before primary school younger children can access reception and kindergardens, usually available at the school locally and of course privately.

If your child is four years old before September, you can apply for a place in a reception class in the same way as you would for any school place. You child must attend school from the beginning of the school year following their 5th birthday.

Reception class is the first year at primary school, but unlike every other school year, it is not compulsory for your child to attend, but it is a good way to introduce your child to life at school.
