There is a closed Facebook group entitled Flexible School Admissions for Summer Borns which also may be of interest to many. Their report was featured on the BBC.
It has become apparent that many LAs are largely ignoring or are unaware of DoE advice from July 2013 on the matter of deferring and delaying reception entry. They appear to be using a variety of tactics involving misinforming parents to force children into starting reception at 4. For example, misinforming that children would have to miss reception year and start at compulsory school age 5 in Y1.
I do hope I have managed the link correctly. I have found it most useful.
