Examining supervisory dyads consisting of a White supervisor and a White supervisee, the authors sought to determine the effects of similarities and differences in levels of supervisor and supervisee racial identity schemas or attitudes on White supervisees' self-reported multicultural counseling competence and multicultural case conceptualization ability. White supervisees in supervision dyads characterized by more advanced White racial identity schemas reported higher self-perceived multicultural counseling competence and obtained higher multicultural case conceptualization ratings than did their counterparts in supervision dyads characterized by lower White racial identity schemas. Implications of the findings are discussed.
