This year's annual update to the nation includes three new features. The first is a Secondary School Improvement Index to assess whether gains in high school graduation rates nationally and by state are translating into better preparation for postsecondary education. The second feature is a focus on homeless students with graduation rate data available for the first time from 26 states, together with a national graduation rate released by the National Center for Homeless Education, signaling that homeless students may be the subgroup with the lowest graduation rates in the nation. The third new component highlights indicators of postsecondary success and provides snapshots of innovations in the school-to-work pipeline as the nation works to prepare more Americans for the increasing demands of the workplace. This year's report also continues to keep the nation's attention on the progress and challenge across the nation and by state in raising high school graduation rates, a critical on-track indicator for young people as they enter adulthood. We conclude with a list of policy and practice recommendations that aim to help the nation reach its goal of a 90 percent high school graduation rate for all students and ensure they are better prepared for postsecondary education in an economy that increasingly demands it. The report also includes a deep analysis of state-by-state data in the appendices. The report is organized into three parts: (1) High School Graduation Trends Across the Nation; (2) Reaching a 90 Percent Graduation Rate for All Students; and (3) Examining the Connection Between High School, Postsecondary, and the Workforce.
