The capacity of the North Central Association Commission on Secondary Schools self-study and team-visit program to effect change in member secondary schools was studied. Change is defined as the rate of implementation of recommendations. As many relevant variables as possible were identified and their interrelationship was investigated. A systems analysis framework was employed to identify and define these variables. They were organized into three categories: recommendation attributes, existing characteristics of schools, and process variables. Data gathered from a representative sample of 57 schools was analyzed. Factor analysis revealed a fourth category of variables, faculty and community attitudes toward and action taken on recommendations. The correlation coefficient achieved (.84) indicated that some of the system of variables related to change as measured by the implementation of recommendations had been determined. The multiple regression equation a allowed an enumeration of the most important variables affecting implementation. The practical implications of this study for the evaluation process are discussed in some detail. (PR)
