Each year, the Community College Survey of Student Engagement ("CCSSE") presents the results of its annual survey--and helps colleges use that information to improve student learning and persistence. "CCSSE" results give community colleges objective and relevant data about students' experiences at their colleges so they can better understand how effectively they are engaging their students--and identify areas for improvement. This year, "CCSSE" is pleased to note that there is an unprecedented commitment--from foundations, accreditation agencies, government agencies, and community colleges themselves--to make better use of data to improve student outcomes at community colleges. An overview of the 2006 cohort's participating colleges and their students follows. A total of 249,548 students from 447 institutions in 46 states are included in the 2006 "CCSSE" Cohort. 2006 "CCSSE" Cohort member colleges enroll a total of 2,684,223 credit students, or about 42% of the total credit-student population in the nation's community colleges. Of the 447 participating colleges, 55% are classified as small (up to 4,499 students), 24% as medium (4,500-7,999 students), 13% as large (8,000-14,999 students), and 8% as extra large (15,000 or more students). Nationally, 56% of community colleges are small, 22% are medium, 13% are large, and 9% are extra large. Colleges reported their locations as 26% urban, 27% suburban, and 47% rural. Fall 2004 IPEDS data indicate that among all U.S. community colleges, 39% are urban, 24% are suburban, and 37% are rural. 2006 "CCSSE" Cohort respondents generally reflect the underlying student population of the participating colleges in terms of gender and race/ethnicity. Part-time students, however, were underrepresented in the "CCSSE" sample because classes are sampled rather than individual students. (About 31% of "CCSSE" respondents are enrolled part-time, and 69% are enrolled full-time. IPEDS shows that the national figures are 61% part-time and 39% full-time.) To address this discrepancy, "CCSSE" results are weighted by part-time and full-time status to reflect the institutions' actual proportions of part-time and full-time students.
