Okay...how's this for fun...
It isn't compulsory to attend at that age, but if you try to then enroll as a first grader the following year (as is fully in your right) they have the right to evaluate your child during the first nine weeks and put him or her in K if they don't pass muster. If they do fine in first, they are okay with it.
Last year I volunteered at my son's school in a first grade room a few times and really had to babysit this little girl she was EVERYWHERE! Hot mess. She needed individual attention for every single minute. Went back the next week and she was in K. They used the fact that she didn't go to K the year before (which is okay) and was unable to function in first grade without one on one help and they gave her about six weeks to settle in.
