This study identified the knowledge, skills, and attitudes needed by teachers and other school staff to encourage high levels of parental involvement. It also developed an evaluation instrument of these factors for future use. The first phase of the project encompassed a review of the literature on teachers' roles in encouraging parental involvement. The second phase consisted of interviews with 12 principals whose schools possessed high levels of parental involvement to identify relevant knowledge, skills, and attitudes. The third phase consisted of the creation of a rating scale based upon principal input that identified the relevant factors. The resulting survey instrument includes 155 dimensions of knowledge, skills, and attitudes of principals for successful parent involvement and 122 dimensions for teachers. The scale itself is appended to the text. Contains 52 references. (MDM)
