A primary school, elementary school, or grade school is a school for primary education of children who are 4 to 10 years of age. Primary schooling follows preschool and precedes secondary schooling.

A preschool, also known as nursery school, pre-primary school, play school or creche, is an educational establishment or learning space offering early childhood education to children before they begin compulsory education at primary school. It may be publicly or privately operated, and may be subsidized from public funds.
