The Civil Rights Project, at UCLA, has just released a new report documenting the intense segregation that occurs at charter schools. The organization has been studying charter schools for seven years and has found that students are substantially more isolated by race and class than at traditional public schools.
70% of black charter school students attend schools with 90-100% minority students, 75% of whom are also black, yet black students make up only one-third of all charter school students. Half of Latino charter students also attend racially isolated minority schools. This data is consistent with earlier data on charter school segregation (see here, here and here.)
25% of charter schools do not report socioeconomic data on its students, drawing into question whether they are providing subsidized lunches to their poor students. Likewise, data on English Language Learners (ELL) are also lacking. Data for California, for example, discuss only seven ELL students in all of its charter schools.
Another finding of the study was that many charter schools draw students from multiple school districts which would bias any comparisons with local traditional public schools which only draw from their own district.
