In August of 2011, NYC launched the Young Men's Initiative (YMI)--an ambitious set of programs across several City agencies aimed at improving outcomes for Black and Latino males. The bulk of YMI's education effort is the Expanded Success Initiative (ESI), which provides funding and support to 40 high schools to help them improve college and career readiness among their Black and Latino male students. While high school outcomes in NYC have steadily increased for all racial and ethnic groups, frustrating gaps between groups of students remain, particularly in the area of college readiness. Among young men of color who entered 9th grade in 2006, only about one in ten graduated ready for college-level work. ESI is designed not only to raise college readiness at the participating schools, but to illuminate successful approaches that ultimately might be expanded throughout the City. The Research Alliance is conducting a mixed-method, longitudinal evaluation of ESI's implementation as well as its impact on a range of academic and non-academic outcomes. Our evaluation will continue until December, 2016. "Preparing Black and Latino Young Men for College and Careers" describes the key components of ESI, the 40 schools that were selected to receive funding, the supports that were available in these schools prior to ESI, and the strategies that they planned to implement in the initiative's first year. The report examines the extent to which the schools' plans align with ESI's design and goals, and begins to look at factors that might influence the potential to apply ESI more broadly (e.g., how similar or different ESI schools are from other schools in the district).
