Academic achievement is regarded an indicator of the success of individuals, schools, universities and countries. ‘Success’ is typically measured using performance indicators such as test results, completion rates and other objective measures. By contrast, in this article we explore students’ subjective understandings and constructions of success, and discourses about ‘successful’ students in higher education contexts that are renowned for being demanding and pressured. We draw on data from 87 semi-structured interviews with students and staff on law, medicine and engineering physics programmes in a prestigious university in Sweden. We focus particularly upon academic expectations, effort levels, and programme structures and cultures. Achieving top grades while undertaking a range of extracurricular activities was valorised in all contexts. Top grades were especially impressive if they were attained without much effort (especially in engineering physics) or stress (especially in law and medicine); we introduce a new concept of ‘stress-less achievement’ in relation to the latter. Furthermore, being sociable as well as a high academic achiever signified living a ‘good life’ and, in law and medicine, professional competence. We discuss the implications of the dominant constructions of success, concluding that (upper) middle-class men are most likely to be read as ‘successful students’, especially in engineering physics.
