This session focuses on advancing career counseling research for first-generation college students (FGCSs) through multidimensional approaches. We will examine FGCS research examples integrating methodologies, such as latent profile analysis, meta-analysis, and longitudinal SEM. Attendees will learn how these projects capture FGCSs’ dynamic career trajectories and subgroup heterogeneity, thereby providing a rigorous empirical foundation for future research and evidence-based practice for FGCSs.
