The present investigation applies a comprehensive sequence of confirmatory factor analysis tests (Vandenberg & Lance, 2000) to the examination of the measurement equivalence of self, peer, and supervisor ratings of non-managerial targets across several performance dimensions. Results indicate a high degree of measurement equivalence across rater sources and performance dimensions. The paper illustrates how this procedure can identify very specific areas of nonequivalence and how the complexity of a multisource feedback system may be represented using such procedures. Implications of these results and recommendations for both research and practice are offered.
