In this paper I explore the musical general knowledge of 46 applicants for places on a secondary Postgraduate Certificate in Education (PGCE) music course. The applicants took a 35-question quiz designed to indicate something of their subject knowledge in connection with aspects of the Western art music tradition, knowledge of Western musical instruments and world musics. I will discuss methodological problems related to the use of the quiz results, then analyse the results. The analysis reveals patterns of strength and weakness in the subject knowledge of the applicants that are related to their educational and other musical experiences. Significant absences in areas of knowledge needed to teach the National Curriculum are detected. I then move on to consider the findings in the light of the new Benchmark Statement (QAA, 2002) for music degrees in the UK. Noting that no given body of knowledge is prescribed in the Benchmark Statement that both describes and governs the content of music first degrees, I raise questions about the difficulties this creates for all concerned.
