Based on a previous report comparing commuter and resident freshmen at the University of Maryland, College Park, the analysis of the similarities and differences of commuter and resident students is extended in the students' third year of college. Dependent commuters (defined as living at home or with other relatives) were compared to students living in campus residence halls. Results included the following: (1) with the exception of one semester, no statistically significant differences were found in the re-enrollment rates of residents and commuters in either the Representative Group (all students) or the Black Group, although the return rates for residents were higher than for commuters each semester; (2) place of residence (on campus or off) appeared to be a more stable category in the Representative Group than in the Black Group; (3) when commuters and residents were compared in terms of cumulative grade point average, number of credits accumulated and hours spent studying, no significant differences were found; (4) commuters worked significantly more hours than residents; (5) residents reported more gains in personal development than did commuters; and (6) regardless of place of residence, students showed a significant amount of change over 2 years on most questions, but the initial relative differences between commuters and residents persisted.
