Is teaching experience necessary for school counselors to feel competent when conducting developmental classroom lessons? The study in this article investigated the relationship between previous teaching experience and practicing middle school counselors' perceived competence in conducting developmental classroom lessons. Results suggested that although teaching experience was significantly related to competence in conducting developmental classroom lessons, this effect decreased dramatically and became nonsignificant when school counseling experience was considered. Implications of the findings for school counselors and counselor educators are presented. (Contains 1 table.)
