Against the background of problems with unarticulated concepts of quality and assessment criteria when assessing music, this article concerns how the limit for approval is constructed and legitimised by jurors when assessing entrance auditions to Swedish specialist music teacher education. The data comprise video documented auditions, focus group conversations, and stimulated-recall based interviews, involving jury members at four music education departments. Social semiotic theory is used to study how jurors assess applicants’ knowledge representations in main instrument tests, what is considered decisive for an approval, and how this set limit is legitimised. Four approaches have been constructed: the demanding education and profession, the supposed capacity of the applicant, the flexible admission situation, and the care of the applicant. What is considered to be the minimum requirement for approval in these constructions differs markedly, which shows a striking difference between the views of jurors within and between institutions on how the applicants’ musical performances on a main instrument should be assessed. These findings are discussed in relation to two possible scenarios of revised admission tests.
