Little has been done to clarify the role responsibilities of the assistant principal; his position is generally looked upon as an internship program leading to the principalship. A survey was undertaken of assistant principals in selected junior and senior high schools in Oregon to determine the administrative responsibilities of assistant principals in Oregon, those responsibilities considered to be primary responsibilities and those that are shared with the principal, and the extent of similarity among the tasks assigned to different assistant principals. Results indicate that assistant principals are delegated a wide range of primary responsibilities, but that there is little consistency in the tasks assigned. Only supervision of the school in the absence of the principal was indicated as a primary responsibility by over 50 percent of the respondents. (Author/WM)
