New York City schools have improved dramatically during the last two decades, including steep declines in dropout rates, increases in high school graduation and college enrollment, and improved attendance and achievement. Yet, despite the overall progress, deep inequities continue to plague the City's education system. At every level of schooling, there have been large, persistent disparities linked to students' race, ethnicity, and neighborhood. These are rooted in longstanding racial and economic inequalities that have been exacerbated by COVID-19. The Research Alliance's new policy brief, "Blueprint for Advancing Equity in NYC Schools," outlines recommendations for how City and District leaders can take a more demanding approach to advancing equity, while sustaining the progress that has been made during the last 20 years. These recommendations include: (1) Set an Evidence-Informed Foundation: Measure What We Seek to Change; (2) Reframe the Equity Agenda: Align Resources With Needs; and (3) Build for the Long Term: Leverage Innovation and Learning to Improve Equity. While these recommendations focus largely on the education system--and decisions that can be made within that system--the "Blueprint" also emphasizes that schools do not operate in a vacuum. Eliminating educational disparities will require addressing larger structures that perpetuate racial and economic inequality. To this end, the "Blueprint" highlights opportunities to link reforms in education to reforms in other systems in New York City. The first task of the next mayoral administration should be to assess how policies and practices "across agencies," including those focused on housing, healthcare, employment, and policing, are either undermining or supporting young people's development and academic success. The "Blueprint" is designed to inform these efforts.
