Each year numerous research studies are conducted on problems in or related to school and college personnel services. Since many of these studies go unpublished, the results are all but lost to a large segment of people concerned with the improvement and operation of the services. The U.S. Office of Education was requested by the National Association of Guidance Supervisors and Counselor Trainers to cooperate in collecting and publishing biennial summaries of unpublished research in the field of school and college personnel work. The present bulletin carries summaries of research studies completed between September 1, 1956, and August 31, 1958. The publication of these summaries can serve at least two purposes: First, they can be used to bring about some improvements in school and college personnel services for such improvements depend to a large degree on the extent to which research conclusions find their way into operational programs. Second--and perhaps more important--they can stimulate, and serve as a base for, further research studies, particularly those in graduate programs. [Best copy available has been provided.]
