I think it depends on the child DS was a mid year in take child for school so he started just after his 5th bday. The 18 months he did of reception did him the world of good. It's sucks that in SA we no longer do this. So new DS will be starting school when they are 5.5yrs old order if they are super ready they will be 4.5yrs old. I was 4.5 yrs back in the early 80's.
