Three standardized measures of child and adolescent behavior are reviewed for their attention to issues salient in the experiences of girls in late childhood and adolescence (ages 12 to 18; American; American and Brown & Gilligan 1992). The Achenbach Child Behavior Checklist and Teacher Report Form (Achenbach and Achenbach), the Behavior Assessment System for Children (Reynolds & Kamphaus, 1992), and the Social Skills Rating System (Gresham & Elliott, 1990) are analyzed. Challenges to psychologists in schools for including the experiences of girls in the knowledge base grounding their practice and research are articulated.
