Mayors and other municipal leaders in cities across the nation are helping expand alternatives for students who struggle in traditional high school settings. Alternatives for high school are new alternative secondary school initiatives that prepare young people to graduate from high school and achieve college and career success through programs characterized by rigor, relevance, and relationships. Progress is evident among high-quality alternatives for high school based on such indicators as increases in high school graduation rates among students participating in these programs, decreases in dropout rates, higher rates of college entry, and preliminary indications that young people will succeed in and complete postsecondary education. This report examines the leadership of mayors, school superintendents, and program innovators as these three types of leaders work together to advance system-wide education reforms and address policy conditions that facilitate the expansion of alternatives for high school. Appended are: (1) Alternative High School Initiative Profiles; (2) Methodology for Report; and (3) Top 10 Factors for Analyzing the Policy Environment for Alternatives for High School.
