Under New York State Education Departments (NYSEDs) approved Elementary and Secondary Education Act (ESEA) flexibility waiver, the states persistently lowest-achieving schools are identified as Priority Schools and may also be placed under registration review (SURR), pursuant to Commissioners regulation 100.18. As a result, Priority Schools, with the support of the larger district and school-community, have an opportunity to develop and implement a whole-school change model with the goal of achieving dramatic school-level achievement gains such that the school is in good academic standing within three years.
