In 2011, the New York City Mayor's Office, the Open Society Foundations, Bloomberg Philanthropies, and over 20 local agencies launched the Young Men's Initiative (YMI), a citywide effort to improve outcomes for Black and Latino young men in the areas of education, health, employment, and criminal justice. YMI is one of the single largest initiatives focused on Black and Latino males in the country, and it is at the forefront of a growing national movement to address the challenges these young men face in a more concerted way. This was exemplified by President Obama's recent launch of My Brother's Keeper, an initiative backed by government, businesses, and more than a dozen foundations that have committed $350 million toward identifying and expanding effective programs for young boys and men of color. Like others in this new generation of initiatives, YMI is attempting to tackle problems that have commonly been perceived as too large to fix. The core education component of YMI--the Expanded Success Initiative (ESI)--is designed to meet two related goals: (1) to increase college and career readiness among Black and Latino male students in participating high schools; and (2) to identify and disseminate effective strategies that might be replicated in other NYC schools and possibly other districts. While it is too soon to know if ESI is having an impact on student outcomes, this report provides a rich description of the first year of implementation (i.e., the 2012-2013 school year) at 38 of the 40 ESI schools. It focuses on elements that are integral to ESI's theory of action and were reported by school staff as having been the most promising for improving student outcomes and school culture. This information is intended to help ESI schools and the NYC Department of Education (DOE) as they refine programming and district-level support through the remainder of the initiative. More broadly, these findings and recommendations can inform efforts in other schools and districts working to better engage young men of color. The five chapters in this report are as follows: (1) Introduction; (2) Data Collection and Analysis; (3) District-Level Implementation; (4) Key Findings; and (5) Recommendations for Policy and Practice.
