The issue raised by this paper is whether the site administrator needs to have formal evaluation skills. These skills are not necessary when there is a competent administrator and a competent evaluator who uses his or her skills within the context of a harmonious relationship with the school staff. However, the rarity of such a relationship, coupled with growing state demands for evaluation of categorically funded programs, indicates that today's principal needs to have some knowledge of the field of evaluation. There are a minimum of ten basic areas that the administrator should have a detailed knowledge of: evaluation design, needs assessment, goal setting, objectives, sampling techniques, philosophy of evaluation, student progress, testing, computer printouts, and record keeping. In addition to the desirability of a harmonious working relationship between evaluator and administrator, public schools would profit from those in decision-making positions having some certification that would document their ability to relate effectively on evaluation issues.
