In 2010, the National Association of School Psychologists approved the "Model for Comprehensive and Integrated School Psychological Services" (or the NASP Practice Model), codifying what an expanded role encompasses in the delivery of school-based psychological services. This study examined the role and function of school psychology practitioners from three Midwestern states with different legal statues and policy initiatives related to the practice of school psychology. A total of 175 practicing school psychologists from Missouri, Illinois, and Iowa reported their actual and preferred practices and completed a self-assessment on their knowledge of the NASP Practice Model. Results showed participants not only identified problem-solving consultation as their most knowledgeable domain of practice but also the activity on which they spent the greatest amount of their time. Analysis by state revealed differential levels of practice devoted to consultation and intervention. Study findings are discussed relative to the potential impact and importance of state law and policy initiatives.
