Portfolios have been used in the authentic evaluation of artists, business professionals, students, and teachers. This paper examines the feasibility of using portfolios to evaluate administrators in training. The document describes portfolios and their uses in administrator-preparation courses, as job applications, and as on-the-job assessment of practicing administrators. A survey of 90 school districts within a 6-county region around California State University, Stanislaus, elicited responses from 35 administrators. Thirty of them said that an administrative portfolio would help candidates applying for public school-administration positions. Twenty-nine administrators said that candidates enhance their job applications by providing a visual image of their qualifications. They also reported that the most important materials to be included in portfolios are those related to evaluation and professional development--such as samples of teacher evaluations, evidence of leadership in professional development, evidence of participation in professional development, and district evaluation reports. They assigned the most importance to the domains of leadership, instruction, and learning environment. Finally, they suggested that portfolios should: (1) use a clear, brief, and organized format; (2) focus on specific strengths of the applicant; and (3) include pertinent, verifiable information. (LMI)
