This handbook is a comprehensive guide to the supervision of the intern for all positions with school administrative responsibilities: principal, superintendent, and middle administrator. It consists of eight sections, the first five of which are introductory, explaining the concept of the internship as a performance-based evaluative technique and summarizing the responsibilities of the supervising administrator and the college supervisor. The sixth section describes the administrative internship program at Texas A&M University and the Ed.D. internship in particular. The seventh section, comprising the main body of the handbook, begins with application procedures for prospective interns, followed by a guide to setting up an individual internship plan, including personal and professional goals, preassessment of competency and interest, and field service projects. Next, specific internship requirements are described, including a demographic study, logs and reports, and a final notebook. Information is also provided on conferences, seminars, on-site visitations, and evaluation. The eighth and final section lists suggested activities for administrative interns in the areas of personnel, curriculum and instruction, organization and scheduling, the school plant, students, school management, and public relations, with additional suggestions for superintendent interns. An appendix is provided, consisting of sample forms for all aspects of internship recordkeeping. (TE)
