Do I need to deregister my child from school?

If your child is registered at a school, you usually need to send a written deregistration letter to the headteacher. Once the school receives it, your child should be removed from the school roll.
Here's a template you can use (UK)

[Your name]
[Address]

[Date]
[School Name]

Dear Headteacher,

Re: [Child Name]

It is after careful consideration that we have decided to take full responsibility for [Child Name]'s education by home educating in accordance with Section 7 of the Education Act 1996.

We therefore instruct the school to remove [Child Name] from the school register with immediate effect, in accordance with Regulation 9(1)(f) of The School Attendance (Pupil Registration) (England) Regulations 2024.

We will ensure that [Child Name] receives an efficient full-time education suitable to their age, ability, aptitude, and any special educational needs.

For the avoidance of doubt, [Child Name]'s last day attending school is [date].

Yours sincerely,
Your Name
