Reliability in assessment centres depends on general and exercise performance, but not on dimensions

Abstract This study contributes to the literature on assessment centre (AC) measurement structure by evaluating whether dimension, exercise or mixed‐model theoretical perspectives are supported reliability outcomes. In a large‐scale ( N candidates = 2917) utilizing Bayesian generalizability theory, we tested estimates configured conform perspectives. Our findings reveal that outcomes for AC ratings greatly depend intentions of researcher. When this intent aligned with traditional dimension perspective, found evidence was unacceptably low (mean .38, SD .15). However, when exceeded acceptable criteria .91, .09). The addition dimension‐ exercise‐related effects reflect perspective did not make an appreciable difference reliability.
