Are you aware of the summerborn campaign? Do you support it? Does your school support it?
It seems to be such a postcode lottery as to whether summerborns (1st April to 1st August) are being allowed to start in reception the term after they turn 5, rather than the term after they turn 4. Scotland seem to get it so right and have very clear rules for deferring/delaying entry, so I really don't get why England can't do the same, consistently (Herefordshire are more willing, others aren't at all). I think it's all a huge concern, and it also seems that some grammar schools are refusing to accept "over-age" 11+ entrants and other secondaries demanding that a child goes into the "correct cohort" and straight into y8 rather than y7! So in theory you could get a primary school to accept a later start into receipting but then a secondary school may trash that supposed good start.
Anyway really keen to hear the thoughts of teachers and heads on this point. Not so keen to hear anecdotal stories of how someone's August born ended up going to Oxbridge and it's never been an issue
For me, my end of July daughter will probably be ready for school at just turned 4 but I'm still concerned about the longer term impact it may have on her academic attainment and also self-esteem. We are also in a grammar area with awful non-grammar schools so I'd like to give my DD the best chance to get into a grammar (if that kind of school does suit her of course).
