There has always been an ambiguity about the “universal” part of universal pre-K. Even in Oklahoma, with the pre-K program that gets the loudest cheers, just three out of four 4-year-olds are enrolled.

Compared with zero, of course, three-quarters is a lot. But imagine if a quarter of 14-year-olds weren’t enrolled in high school. Universal means universally available, not universally used.
