College completion is a priority for federal and state governments as well as policy makers and funders. Yet a major barrier exists for many students seeking college certificates or degrees. The barrier is that more than half of community college students and about one-quarter of students at four-year universities are not well prepared to succeed in college and are referred into developmental education to take remedial courses in math, reading and writing. However, many of the developmental education options these students are offered do not effectively or quickly provide students with the skills they need to succeed in college. President Obama, meanwhile, has called for all Americans to restore the United States to its former position as the country with the highest percentage of adults with postsecondary credentials. In order to meet the president's ambitious goal of an additional five million community college graduates by 2020, much more attention must be paid to the question of how to help students succeed in college--especially those students who face barriers of poverty and lack of preparation. Furthermore, addressing developmental education is crucial for many grantmakers in reaching their goals. Reforming developmental education is critical for funders who seek to improve college completion rates and the country's economic productivity. This funder's guide captures themes and lessons from an ongoing body of work that has been supported by a number of funders working to reform developmental education. In June 2011, these funders met with prominent researchers and higher education leaders to examine promising strategies to accelerate students' progress toward earning degrees and credentials by reforming developmental education and by ensuring that more students enter postsecondary institutions prepared to succeed. This brief summarizes key insights from the gathering, from research and from funders' work to identify promising areas for grantmakers to support. (Contains 5 footnotes.)
