Children must get an education between the school term after their 5th birthday and the last Friday in June in the school year they turn 16. Each school decides its uniform and must not discriminate based on sex, race, disability, sexual orientation, gender reassignment, religion or belief. Children can leave school on the last Friday in June if you’ll be 16 by the end of the summer holidays.
