School counselors completed measures of school counselor activity and role beliefs; competence with lesbian, gay, bisexual, transgender, queer, questioning, and intersex (LGBTQQI) issues; and school-based LGBTQQI advocacy and awareness. Hierarchical multiple regression identified that LGBTQQI clinical skill predicts school counselor LGBTQQI advocacy and awareness, adjusting for school counselor demographics, sexual-affective and gender identities, activity beliefs, building level, and LGBTQQI training. We discuss implications for school counselor training and practice.
