"The schools could probably ameliorate the problem with a little creativity and by banning test prep for four-year-olds."
Huh? Whether I prepare my child for a test is my decision, NOT the government's. Even if you thought the government should intrude in this manner, how would you enforce such a law?
If there is a gifted program, I think should children should be added (or removed) each year based on some reasonable criteria. If the focus of a gifted program is advanced work in academic subjects, as I think it should be, admit students to those classes based on prior performance in those classes and/or test scores in those subjects.
