Clinical training and counselor competency are essential for ethical practice when working with multiethnic, lesbian, gay, bisexual (LGB), and transgender clients. In this study, the author examined how multicultural courses related to students' (N = 286) LGB and multicultural competencies. Self-reported multicultural and LGB competencies varied significantly depending on the number and types of diversity education reported. Multicultural courses significantly predicted students' multicultural, but not LGB counselor competency. Political conservatism was the strongest predictor for both multicultural and sexual orientation competencies.
