Data from the public health field indicate a shift in emphasis from treatment models to wellness models which focus on individuals' health and how to maintain it. Similarly, school psychologists can enhance and maintain students' competence, thereby reducing the need for remediation. This would create a new role for psychologists in the schools, a specialty in educational school psychology. An educational school psychologist would strive to build students' competence by educating school personnel about research developments which can improve student competence, by implementing intervention approaches, and by conducting research and evaluation to determine the effectiveness of interventions and to generate and expand knowledge. Specific examples of these functions for the educational school psychologist include: (1) educating teachers about research findings which relate teacher practices to student achievement; (2) offering in-service training to teachers on behavior modification techniques which have been found to be effective in improving student achievement and behavior; (3) developing school materials in accord with instructional system design; (4) helping teachers prepare adjunct questions for text materials and teaching students metacognitive strategies to improve reading comprehension; (5) demonstrating to teachers the usefulness of criterion referenced tests; (6) developing programs of computer-assisted instruction; and (7) conducting study skills training programs and test anxiety reduction training programs for students. These activities are samples only. Continuing research will modify and expand these functions and more effective interventions will be developed. The vital functions for the educational school psychologist are to train others in order to have the important multiplier effect, and to keep abreast of new developments as they occur.
