NOT kidding. I've read every study I can get my hands on. I've even read years of the Head Start data... that's mind numbing. I should get an honorary Masters degree JUST for reading the Head Start research.

I've been looking for it and I can't find it. If anyone here knows of any longitudinal studies on preschool that do NOT focus on poor kids or poor African American male children PLEASE post it.

I want to see PROOF that children who attend full academic preschool programs between the ages of three and five show a significant difference in measurable standardized testing outcomes in math, reading, science, social studies, and writing beyond the entry into second grade.

NOT poor kids. I'm specifically interested in lower middle class, middle class, upper middle class, and upper class children.
