Two recent reviews have attempted to summarize findings quantitatively regarding assessment center (AC) construct-related validity (i.e., Lance, Lambert, Gewin, Lievens, & Conway, 2004; Lievens & Conway, 2001). Unlike these previous studies, which reanalyzed individual multitrait-multimethod (MTMM) matrices from previously published research, the authors recoded and combined past matrices into a single MTMM matrix. This matrix, comprised of 6 dimensions each measured by 6 exercises, was then analyzed, providing a more generalizable set of results. Both dimensions and exercises were found to contribute substantially to AC ratings. Specific dimensions (i.e., communication, influencing others, organizing and planning, and problem solving) appeared more construct valid than others (i.e., consideration/awareness of others and drive). Implications for AC design and practice are discussed.
