Of course, although this list suggests the eligible age to start kindergarten by state, this doesn’t mean you have to start your child if he or she is the appropriate age by the date in question. Even in those states where kindergarten attendance is mandatory, there is usually an opt-out available or the option to enter a transitional kindergarten class or a program like Head Start. (Transitional kindergarten program are run over 2 years for those kids who were not really ready. The curriculum is at a slower pace and there is a lot less pressure in this type of setting.) Likewise, many states offer early entrance programs for those children who are ready to start school but don’t meet age requirements.

If you are unsure about whether or not your child is ready, see if your state offers a kindergarten assessment or pre-entrance testing. Usually, these tests not only assess academic readiness but social and emotional readiness as well.
