From the article.......The two most recent studies show that, since the implementation of the voucher program, reading scores across all Milwaukee schools are falling.
That's a bold statement
The U.S. Department of Education’s National Center for Education Statistics has compared the performance of students in district and charter schools, reporting, “After adjusting for student characteristics, charter school mean scores in reading and mathematics were lower, on average, than those for public noncharter schools.” While there is reason to be quite cautious about inferring policy implications from such research—because it cannot determine how much students are actually learning during the school year and because charters spend less than do district schools—the results are hardly compelling. Stig Leschly, executive director of the Newark Charter School Fund, has observed that only about 200 of the thousands of existing charter schools “really close the achievement gap.”
He also is skeptical of several other studies.
