Chapter Two details the students' personal, academic, and social backgrounds. Chapter Three describes experiences of students in the study abroad programs. Chapter Four reviews the formal, academic goals of programs and assesses their success in relation to those goals with the exception of effects on foreign language proficiency which is the topic of Chapter Five. Chapter Six examines the cultural impacts of the study abroad experience on participants. Chapter Seven addresses the importance of these experiences on later careers. Chapter Eight sets out the results of a statistical analysis designed to identify some of the key determinants of changes in student competences related to study abroad.
