This report illustrates the steps in the development of an evaluative model for non-teaching faculty, using the school media specialist as an example. The model measures how the professional applies knowledge of a given content area to improve learning in a particular school situation, and consists of three parts: (1) documentation developed by the media specialist (or other non-teaching faculty) and presented in a portfolio, (2) interview questions for randomly selected school personnel and students, and (3) a list of items to be checked by observations. The effectiveness of the media specialist would be evaluated in the areas of media selection, management of the media program, and utilization of media resources by faculty and students. While the specifics of the model would change for other non-teaching faculty, the basic components are designed to evaluate solely those skills that influence the effectiveness of the program for which he or she is responsible.
