Does anyone know how things work if a child doesn't go into reception and stays with them?

Am i right in thinking reception isn't compulsory, so parents wouldn't have to say they are home-schooling? I would carry on having the child 4 days a week, so would I just carry on following the EYFS with them?

I see two options. Firstly, parents say they're home-schooling and I'm providing childcare. In that case, they're responsible for the education. Or, I'm the educational setting and follow the EYFS to provide the education.

I assume I could carry on claiming their 30 hours funded childcare for as long as they stay with me. Parents are waiting for a suitable school place, which possibly happen in time for September, but the child will start school as soon as they have a place. It's not deferring school for a year, it's waiting for a place to become available.

Has anyone got any experience or thoughts?
