‌Not only is there a mandatory age for children to remain in education until, but there's also a compulsory starting age. However, contrary to popular belief, children aren't required to start school at Reception age. For example, if your child's fourth birthday falls between September 1, 2021 and August 31, 2022, they would likely start school this September, reports the Liverpool Echo. If you feel your child isn't ready to start school at this age, they can begin later, provided they're in school by the September following their fifth birthday. You can then request your child's later start when you apply.
