In presenting this review of current theory and practice in graduate level pre-service and in-service education for school administration, one major purpose has been kept in mind, namely, to provide some significant and stimulating documentation with respect to on-going plans, programs, and problems. The inquiry, upon which the material presented is based, was essentially an invitation to the institutions and State departments of education canvassed to share with others, accounts of such experiences and activities as might have value as constructive leads and suggestions. Without the very generous collaboration of deans, department heads, and staff members of the cooperating institutions and State departments such a comprehensive survey would not have been possible. It is hoped that the published results of this inquiry may serve to stimulate further cooperative study in which institutions, lay school officials, and professional administrative groups may all have a part. This bulletin is presented in two parts: (1) Review of Current Practice, Theory, and Opinion in 62 Representative Institutions at the Graduate Level; and (2) Current Practices and Thinking Related to the In-Service Improvement of Administrative Personnel as Reported by 36 State and Territorial Departments of Education. Appended are the following: (1) Institutions participating in the study, and a copy of the covering letter and schedule of information; and (2) State departments of education participating in the study, along with a copy of the covering letter and schedule of information. A separate bibliography is provided for each of the sections of this bulletin. (Individual chapters contain footnotes.) [Best copy available has been provided.]
