The teacher in the school of tomorrow will have a variety of roles. One of the more important will be that of diagnostician. Perceptive assistance for the teacher as diagnostician is available from the school psychologist, the social caseworker, the guidance worker, and the reading clinician. The services of all district personnel should be utilized. The professional personnel in the school should allow more time for the teacher as a person, as a reading teacher, as a facilitator, and as an interpreter of the behavior of children. Cross-discipline synthesis is necessary. (Author/BS)
