The Validity of Assessment Centres for the Prediction of Supervisory Performance Ratings: A meta-analysis
نویسندگان
چکیده
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 (N1⁄4 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 q .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.
