You should make all efforts to continue to send your child to their existing school until the day they can start in the new one. If this is not possible, you should ensure that your child continues to be educated during the period they are not enrolled at a school.
You will need to provide confirmation to the existing school as to the arrangements you will put in place to ensure this happens.
The existing school will also refer the child to the Education Safeguarding Service who will ensure you are contacted in order to discuss the support you intend to obtain to make this happen.
If the decision has been made to move school, then it is requested that parents download and complete the application form for In-Year admissions, in order to apply to transfer from the current school to a new one.
If your child has an EHCP please see this page about moving schools if you have an EHCP
Transfer of school should ideally be planned to coincide with the house move. If this is not possible, all efforts should be made to continue to attend the existing school until the start date for the new school.
