Community colleges have experienced a dramatic shift in focus and direction over the past 25 years. The impact of federal policy that emphasizes employment over education and the increased pressure for community colleges to meet the needs of local industries has led experts to ask whether or not contemporary community colleges are best serving their students. As a bridge between public K-12 schools and higher education, community colleges were designed as a gateway for groups of students who would otherwise be excluded from higher education, most notably poorer and minority students. Ideally, this education sector should be a democratizing force in American society. Yet community colleges continue to struggle with their mission, and a variety of factors make it increasingly difficult to meet it. The articles in this special issue of the ANNALS examine the role of community colleges and how they respond to an emerging set of challenges.
