Summary.—An investigation was carried out among past students of University College, London, attempting to discover if there was any association between academic achievement and various social and psychological factors. The chosen criterion of success was graduation with or without delay. A questionnaire was sent to all the students of the College who, having entered for a degree course between 1948 and 1951, had eventually left without obtaining a degree. A similar questionnaire was sent to a control group of graduates. The analysis indicated a relationship between the criterion and each one of the following:Type of school attended.Possession of a grant or scholarship.Parents' education.General health (as reported by the student).Personal and social relationships.Eventual occupation.Motivation, as estimated by: Reasons given for choosing the college; Interest in subject of study; Age at choice of caree
