Analysts of charter school reform have recently begun to investigate the enrollment patterns of special student populations, namely, low-income students, students classified as special education, and those with English language learner status. Using 3 recent years of data from the New York State School Report Cards and analyzing the charter population at the school level, the authors found that English language learners are consistently underrepresented in charter school populations across 3 academic years. Conversely, students who qualify for reduced-price lunch are overrepresented and students eligible for free lunch are approximately proportionally represented. This gap in enrollments of English language learners is confirmed by comparing to a population estimate drawn from data from the 2006-2008 American Community Survey. These patterns remain generally constant for all school years observed, but the distribution changes slightly as the total number of charter schools operating in New York City increased between 2005-2006 and 2007-2008.
