Could someone tell me the exact age rules (down to the month) for starting pre-K in America? Does it vary between states? (I'm aware not all states provide it.)
For comparison, in England children may enter Reception the September after their 4th birthday. So the very youngest children in Reception will start at 4 years, 0 months, and the average child will start at 4 years, 6 months.
Edit: thanks, all — I didn't realise the term was so variable in the US. For context I was trying to make sense of several academic papers that discuss effects of pre-K. It looks like I will need to dig into more specific programmes (Tulsa pre-K, etc.) to understand the age ranges covered.
