Suggestions are given for evaluation of school principals by teachers. In developing an evaluation instrument to appraise principal performance, one need not start from scratch. The Organizational Climate and Description Questionnaire (OCDQ) of Halpin and Crofts (1963) is a useful tool for pinpointing areas of strength and weakness. Four subtests of this instrument focus on principal behavior and relationships to teachers. The OCDQ is a starting point for an instrument developed to rate principals on a 5-point scale for each of 10 characteristics of the relationship with teachers. Results from either the OCDQ or another scale could be used by the principal to develop a portfolio. Some guidelines are offered for the construction of a professional portfolio by principals, both as a record of professional accomplishments and a self-evaluation tool. A portfolio is more subjective than traditional evaluation tools, but it is more authentic and has personal meaning for the developer. (SLD)
