The Parent Opinion Inventory was developed to accomplish three goals: (1) to assess parents' attitudes toward their children's school and its programs; (2) to provide an opportunity for parents to make specific recommendations for improvement; and (3) to provide decision-making data relative to program development, policy formation, administrative organization, faculty development, and community relations. The 53 items of Part A deal with intra-student body relationships, school information services, parent involvement, educational objectives, intra-school problems, school program factors, innovative programs, student activities, support services, auxiliary services, and general psychological climate. Questions are of the strongly agree-agree-disagree-strongly disagree-no opinion format. Part B consists of five open-ended questions soliciting recommendations for improvement. This manual includes a description of the development of this inventory, instructions for administering it, instructions for scoring and interpreting the test, and reliability and validity data. One copy of Part A and Part B are included in full. (BW)
