Los Angeles charter students gain 50 more days of learning in reading and 79 days in math than similar students in district schools, concludes a study by Stanford University’s Center for Research on Education Outcomes (CREDO). Low-income Hispanic students did even better, gaining 58 additional days of learning in reading and 115 more days in math.
Citywide, 48 percent of charter schools have significantly larger learning gains in reading, while 44 percent do so in math, the 2014 CREDO study found. Thirteen percent of Los Angeles charter schools have results that are significantly worse than their district school peers in reading and 22 percent perform worse in math.
Urban charters serving low-income students show the strongest gains in recent research.
