This study explored whether latent phenomena could be identified to classify students based on their patterns of involvement in cocurricular group experiences. The sample was comprised of 11,209 seniors from 50 institutions. A total of 4 latent factors were identified and students were classified into one of 8 latent classes. Findings offer new analytic and conceptual approaches for use in college impact research as well as a useful heuristic tool to assist student affairs professionals in designing and targeting educational interventions.
