Louise sent me the details for this as it doesn’t seem to be well known, even though Hampshire is one of the most flexible counties.
I really wasn’t aware of this, so thank you very much Louise for the details!
I’m sure it will be useful to a LOT of NHM Readers.
There’s also a Facebook group called “Flexible School Admissions for Summer Borns” if you want to join the community.
Thank you to Charlotte for the following links too: https://www.gov.uk/government/publications/summer-born-children-school-admission
