I have a March birthday and I started school in the April after I turned 5. I wonder whether it might be better to have a system where, instead of waiting a whole year to start school if you are a summer born, there is flexibility about when to start during the year for everyone.
So if you are an autumn born you can start in September or January.
If you are a spring born you can start in January or April.
And if you a summer born you can start in April or the following September.
So in effect everyone starts much closer to their 5th birthday.
I'm not sure however, whether people would feel disadvantaged because their children missed part of reception. I'm also not sure how it would sit with nurseries/pre-schools etc.
