There is not a single, universally agreed-upon definition of what constitutes a "state-funded pre-kindergarten program." Some states might offer funding but only to limited populations or through highly restrictive eligibility criteria. Therefore, the exact number of states with *no* state-funded pre-K program is difficult to definitively state.
However, it's safe to say that the number is very low, if not zero. Most states have some form of state-funded pre-K, even if it's not universal or fully funded. The level of funding and accessibility varies considerably.
