This report describes the model used by the Oregon State System for Higher Education to assess the impact of higher education on the growth and change in students as a result of participation in higher education. The model prescribes assessments of general knowledge and abilities, learning environment, major field knowledge, degree completion, professional licensure, employment, and customer satisfaction (both alumni and students). Specific assessments used by individual colleges and universities in the Oregon State system are described including Southern Oregon State College, Oregon State University, Portland State University, University of Oregon, Eastern Oregon State College, and Western Oregon State College. The implications of these assessments for improving the education system are considered. (JPB)
