Latinos represent almost one quarter of students enrolled in pre-kindergarten through twelfth grade in public schools. Between 2011 and 2022, Latino postsecondary enrollment will increase by 27% -- the largest rate of increase of all groups. This report examines the role of high school counselors in assisting Latino and other underrepresented students through their transition to college. Public high schools continue to emphasize the importance of planning for postsecondary education. For Latinos and other underrepresented groups, counselors can act as a catalyst in the development of postsecondary aspirations and the formation of "college knowledge." The study uses site visits to examine the challenges and successes of providing college readiness counseling to Latino students. It also includes recommendations for improving college counseling, access, and success for Latinos.
