The current meta‐analysis of the selection validity of assessment centres aims to update an earlier meta‐analysis of assessment centre validity. To this end, we retrieved 26 studies and 27 validity coefficients ( N =5850) relating the Overall Assessment Rating (OAR) to supervisory performance ratings. The current study obtained a corrected correlation of .28 between the OAR and supervisory job performance ratings (95% confidence interval .24≤ ρ ≤.32). It is further suggested that this validity estimate is likely to be conservative given that assessment centre validities tend to be affected by indirect range restriction.
