The role of school psychologists and counselors in assessment is well established. With the current emphasis on collaboration in schools and the use of a pupil services model to deliver services, it is important to examine ways in which school psychologists and counselors can work together for assessment purposes. School psychologists' involvement in assessment begins with a student who has been referred by a parent or teacher for academic or behavioral difficulties. As part of the assessment process, an individual test of intelligence and an achievement test are likely to be administered. Counselors use assessment information to clarify concerns of clients, to plan programs or interventions and evaluate their effectiveness, to provide career planning information, and to assist clients in understanding themselves. School psychologist and counselor assessment processes have differing emphases that are complimentary to each other. The multidisciplinary approach to assessment required by recent legislation is especially suited for these two groups of professionals to work together in a collaborative manner. In this way a more complete picture of students' needs can be developed and service delivery can be enhanced. (JBJ)
