Charter students outperform non-charter students in nearby schools, according to Caroline M. Hoxby, a Harvard economics professor. Charter students were 3 percent more likely to be proficient on their state’s reading exam, and 2 percent more likely to be proficient in math.
While the American Federation of Teachers’ negative findings relied on 3 percent of fourth-grade students in charter schools, Hoxby analyzed scores for “virtually 100 percent” of fourth-graders in charter schools and compared them to students at the nearest public school, reports the New York Post.
According to the latest data, which looked at API growth gains from 2003 to 2004, 64.4 percent of charter schools increased their API scores, compared to 61.1 percent of non-charter schools. Charter schools increased their API scores by an average of 12.9 points, compared to 7.3 points for non-charter schools. In addition, 60.4 percent of charter schools met or exceeded their API growth targets, compared to 54.1 percent of non-charter schools. On average, charter schools also surpassed their API growth targets by 7.5 points, compared to 2.1 points for their non-charter counterparts.
California now has 537 charter schools with 180,000 students.
