Oh nonsense. The quicker the NEA can get their hands on your children, the quicker they can indoctrinate them into the joys of gay marriage, the evils of corporate America, scare them about global warming, etc.
Where in the world did they get the idea that the intention of full day kindergarten was to enhance long-term achievement of a bunch of 4-year old kids?
The intention is to swell the ranks of the teacher's unions with means more dues collected which will enhance the long-term wealth of the Union executives.
No one gives a damn how those 4-year old kids do. That's not the point. Unions (and government) are like any other business... they want to keep growing.
