CA is a bit more flexible on early entrance. Kids must be 5 by Dec. 2 to enter K. The minimum age for enrollment in 1st is also 5. So DS (with late Nov. b-day) was enrolled in K until he turned 5 and was then switched to 1st midyear.
Or they have to have gone through K at a private school and have proof of it (homeschooling does not count as far as I could find out...). Once they hit the door of the K classroom the teacher can just wave at them and send them up to first (what happened with Wolf). It's ridiculously silly in my opinion.
