1) Co-location is nothing new. Public schools have been co-located with other public schools in NYC since the school system was created in 1898.
2) How many public schools are co-located? 1,150 (63%) of the city’s 1,818 public schools are co-located.
3) But how many are charter schools? Of these 1,150 co-located schools, only 115 are charter schools.
4) Co-located schools do not cause overcrowding. Analysis by the Independent Budget Office and NYC Charter Center shows that buildings hosting co-located schools tend to be less crowded than single-school buildings, and those with charters are even less crowded.
5) Charter schools and other co-located small, theme-based high schools are improving student achievement. 79% of charters posted higher proficiency rates in math than their “peer” schools; 54% had higher rates in reading; a multi-year MDRC study has shown that the smaller high-schools have boosted graduation rates by at least 10 percentage points.
