In the United Kingdom, children usually start school earlier than in many other countries, which is important for expats to understand. For expats, compulsory education begins at age 5, but most children start primary school at age 4 in a reception class. Expats in the UK can choose to delay entry until compulsory school age, but many families opt to start at 4 so their child settles in with peers. Before reception, children may attend nursery or preschool, which is optional and can be privately funded or partially government-funded. Expats in the UK should be aware that school years are based on the academic year, meaning children start school in September following their fourth birthday. This can feel early for some expats, so understanding the system helps families prepare emotionally and practically. Early school entry is normal in the UK and is designed to support gradual learning through play-based education in the early years.
