Chalkbeat correctly pointed out why integrating Brooklyn's District 15 middle schools had different roots than District 28 in Queens. According to Chalkbeat, District 15's integration program was parent led and resisted pushback from other parents. Moreover, the parent advocacy in District 15 is quite liberal and supports the Mayor and Chancellor when it comes to eliminating the standardized test for the specialized high schools. Finally, the middle schools had a districtwide middle school screening program that saw many students leave their neighborhood to other middle schools in the district.
By contrast, the proposed District 28 integration plan was spearheaded by the now departed Superintendent who didn't bother to ask her parents what they thought. The DOE actually promoted her for her incompetence Moreover District 28 parents in the Forest Hills and Rego Park communities are strongly opposed to any integration plan that require their children to be bused out of their neighborhoods. Finally, these parents also support standardized testing for the specialized high schools.
In summary, what might work for District 15 is a potential disaster for District 28 when it comes to integrating the middle schools.
