Performance measures of personality—narratives, Rorschach, and drawing techniques—provide continuing comprehensive assessment resources for school psychologists. These measures are examined for assets, limitations, and applications consistent with a new practice model for culturally competent school-based services. Cultural competency is informed by a generic training model and illustrated by contents of a public sector California training program. Expanding cultural competency training opportunities in all school psychology programs can integrate assessment, intervention, and outcome evaluations using performance measures within a context of guidelines and ethical responsibilities. © 2007 Wiley Periodicals, Inc.
