The Bureau of Labor Statistics project that more than half of all new jobs through 2014 will require at least some college experience. Yet scores on the 2008 ACT[C] national college admission and placement exam suggest that only 22 percent of high school students are likely to succeed in first-year, credit-bearing college courses. Outdated high schools are yielding graduates unprepared for today's knowledge-driven economy. Governors, state legislatures, boards of education, education chiefs, and business leaders are responding to this challenge by implementing the policies contained in the 2005 "Action Agenda for Improving America's High Schools." This publication gauges state progress since the release of the original report and reiterates that the agenda for state action must continue to center on college- and career-readiness to help maintain U.S. competitiveness. The update offers new ideas and practices, showing state leaders how to: (1) Restore Value to the High School Diploma; (2) Redesign High Schools; (3) Improve Schools by Providing Excellent Teachers and Principals; (4) Set Goals, Measure Progress, and Hold High Schools and Colleges Accountable; and (5) Improve Education Governance. This report represents the four partner organizations' shared vision for the changes needed in today's high schools. (Contains 120 notes and 2 figures.)
