The School-to-College Report is drawn from a new database that links public K-12 and higher education data, making it possible to report in detail how Massachusetts public high school students are performing in the Commonwealth's public postsecondary institutions. The report's findings will help educators and policymakers develop sound policies and practices for increased college readiness for all students. College readiness is generally understood as a student's ability to successfully complete first-year college-level courses without needing developmental (remedial) coursework. The inaugural 2005 report covers information on students who graduated or obtained a certificate of attainment from a Massachusetts public high school in spring 2005 and enrolled in a Massachusetts public postsecondary institution in fall 2005. In addition to this overall state report, each high school in the Commonwealth enrolling ten or more students in Massachusetts public postsecondary institutions will receive a detailed report outlining their graduates' performance in higher education. Overall the 2005 high school graduate cohort is making progress in higher education (more than 80% persist beyond the first year), but the data shows that too many students required remediation. The findings of the School-to-College Report suggest that more needs to be done to prepare all public high school graduates for college. The Massachusetts Board of Higher Education and the Department of Education are committed to supporting policies, practices, and initiatives that will boost the number of students who graduate from high school college-ready. This Report should serve as a catalyst for K-12 and higher education partners to further align high school and college expectations and curriculum and to work together to provide every student with the foundation needed for college success. Appendices include (1) Background and Methodology; and (2) Data Notes. (Contains 5 footnotes.)
