An assessment center can be used to identify school personnel with administrative potential and to discover what training programs are needed. Run by a group of cooperating school districts, the assessment center consists of three sessions and is held in a place convenient to all participants. Potential administrators are nominated by their superintendents to undergo the assessment process. Assessors are chosen from among regular full-time school personnel and trained by the center director. Assessment activities consist of group exercises, a written "in-basket" exercise, an exercise with a middle-school student, problem finding, an interview, and standardized tests including the Cooperative Reading Test and the Argyris model of the Scenario Test. Before coming to the center, participants prepare written descriptions of their present positions and of desired positions as well as a background information form. Three weeks later, a session is held to give each participant an evaluation report. The participant then decides whether to put the report on file for placement purposes. Two weeks later, a final session is held to design training programs to strengthen identified weaknesses. In spite of some deficiencies, the assessment center is successful in providing data for use in administrative selection and promotion. (Author/JM)
