Using data from Achieving the Dream: Community Colleges Count, this issue of "Data Notes" looks at the relationship between institutional size differences at Achieving the Dream colleges. Nearly half of Achieving the Dream colleges are classified as small, but these colleges account for only 11 percent of students in the fall 2002 cohort. Only 29 percent of colleges are classified as large, but they account for 68 percent of students. This issue makes the point that while these colleges differ in terms of size, locale and student demographics, they face the same challenges and share a commitment to improving student outcomes.
