Abstract

Reviews of self–supervisor, self–peer, and peer–supervisor ratings have generally concluded that there is at best a modest correlation between different rating sources. Nevertheless, there has been much inconsistency across studies. Accordingly, a meta-analysis was conducted. The results indicated a relatively high correlation between peer and supervisor ratings (ρ= .62) but only a moderate correlation between self-supervisor (ρ= .35) and self-peer ratings (ρ= .36). While rating format (dimensional versus global) and rating scale (trait versus behavioral) had little impact as moderators, job type (managerial/professional versus blue-collar/service) did seem to moderate self-peer and self-supervisor ratings.
