On Wednesday, the New York State Education Department (SED) released scores from the third year of the Common Core 3-8 Assessments.   

Performance by African-American and Hispanic students in charter schools far exceeds that of their district counterparts. In Math, African-American and Hispanic charter school students outperform their district peers by +23.9 percentage points, and +18.4 percentage points, respectively. Gaps in ELA are smaller but still significant with a gap for African-American students in proficiency rates of +9.9 percentage points and for Hispanics of +6.8 percentage points. Given that charter schools enroll mostly students from these two subgroups (over 90%), this finding is significant and highly promising. Further, for students identified as economically disadvantaged, charter schools once again outperform their district peers.

Today’s IBO report, Charter Schools Versus Traditional Public Schools: Comparing the Level of Public Support In School Year 2014-15,  shows that charter schools receive significantly less public support than do traditional district schools.  When compared to 2009-10, the last year for which the IBO calculated the data, the gap between traditional district schools and charter schools has grown more than five-fold. In fact, on average, charter schools receive over $1,400 less per pupil than traditional district schools compared to the $250 less per pupil they received in 2009-10.

Today, the New York City Independent Budget Office released a new report, School Indicators for New York City Charter Schools: 2013-14 School Year. The IBO has put out a series of similar reports for NYC traditional district schools for the last three years; this is the first such report on the charter sector. The report is a straightforward presentation of data and, commendably, takes pain to avoid editorializing.

I was disappointed to read in a recent news article Mayor de Blasio’s pronouncement that, “…district schools will share where charters will not.” I commend the mayor for opening up more PROSE schools and allowing a percentage of district schools more freedom and flexibility, but his statement that charters are not sharing is simply untrue.

The IBO has just confirmed what we have long known – charter school students stay in charter schools at higher rates than students in nearby traditional public schools (TPS). Even more counter to charter detractors’ claims– fewer charter school special needs students leave their schools than nearby special needs district students.

The report no longer includes an overall grade for each school, but instead presents multiple ratings on different aspects within 5 categories for charter schools: Student Progress, Student Performance, School Environment, Closing the Achievement Gap, and College and Career Readiness.

In Why the Gap? English Language Learners and New York City Charter Schools, a new report from the Manhattan Institute, Dr. Marcus Winters uses NYC DOE data from school years 2008-09 to 2011-12 to follow charter and district school ELLs over time. (Winters previously studied special education in NYC charter schools.)

New York State entered the 2013-14 school year—the second year of the Common Core era—with a pointed awareness of the challenges revealed by the 2012-13 test scores.
