It's about great public schools.



Public charter schools are judged by their results: whether or not students are achieving academically and being well prepared for success in college and beyond. Charter schools align to the same New York state standards, and take the same state exams, as other public schools. If a charter school isn’t helping students achieve, it can be closed.

This year’s results confirm the trend - of many years - that NYC charters are getting strong results for students while continuing to close the proficiency gap.

Charter math proficiency rates increased 7.8 percentage points, from 51.7% to 59.5%, compared to district growth of 4.9 percentage points, from 37.8% to 42.7%.

Charter ELA proficiency rates increased 5.2 percentage points from 43.0% to 48.2% compared to district growth of 2.6 percentage points from 38.0% to 40.6%. Charter math proficiency rates increased 3.0 percentage points from 48.7% to 51.7% compared to district growth of 1.3 percentage points from 36.5% to 37.8%.

2015-16: Major Gains Seen in Charter Student Achievement

NYC charter schools made significant gains, and outperformed their district counterparts in both ELA and Math. As the sector has done for the past three years, math proficiency continues to exceed district averages. Most encouraging is the fact that charters outperformed the district in ELA for the first time since the transition to the Common Core assessments in the 2012-13 school year (43.0% vs. 38.0%).

2014-15 State Test Score Analysis

2013-14 Test Score Analysis

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. Gains made in Math are particularly notable—over nine percentage points in proficiency (the largest gain for any group or sector)—and underscored by data showing that 15 of the 20 highest gainers among New York States’ high-poverty schools were charters (most located in NYC).

CREDO Study: Urban Charter Schools Outperform Traditional
School Peers

Stanford University’s Center for Research on Education Outcomes (CREDO) released a comprehensive Urban Charter Schools Report and 22 state-specific reports that combine to offer policymakers unprecedented insight into the effectiveness of charter schools. Across 41 regions, urban charter schools on average achieve significantly greater student success in both math and reading, which amounts to 40 additional days of learning growth in math and 28 days of additional growth in reading.

Steal This Plan

New York City Mayor Bill de Blasio announced a new School Renewal Program to improve 94 of the city’s most struggling schools. The program includes practices that are hallmarks of top charter schools, but a comparison of Renewal School plans to charter school practices reveals consistent differences in urgency and intensity. As NYC DOE continues to define, implement and strengthen this high- stakes program, as well as prepare support and turnaround plans for hundreds of other schools, charter schools stand ready to share their work.

2012-13 Test Score Analysis

Charter Center CEO James Merriman says we “should applaud the impressive scores of highly successful charters, including the Success, Icahn, Achievement First, and Uncommon Schools networks, and independent schools including South Bronx Classical Charter School and Bronx Charter School for Excellence, as well as those traditional district schools that are beating the odds. If there was ever a time to learn from our best schools, whether charter or district, it’s today.”
