History repeats itself. Unfortunately, so does irresponsible analysis. For the 20 or so years that I've been studying charter schools, the attacks on charters have morphed over time. Early on, it was said that charter schools were going to admit only the most advantaged students. When that clearly didn't come to pass, the attack line shifted to assertions that charters were more racially segregated than other schools. A study in the early 2000s by Gary Orfield seemed to confirm that: It showed that racial concentration in charter schools was higher than in nearby district schools.
