Perfectionism is a multidimensional construct composed of adaptive and maladaptive aspects. Perfectionism has been found to be at a higher level in the school setting where performance education and high academic expectations are at the forefront, and in the field of music where the evaluation made by other people is more because of the nature of the work. The study sought to identify whether the sub-dimensions of perfectionism of middle school and high school level conservatory students receiving professional music education differed in terms of various variables. The study group consists of middle and high school students between the ages of 10-18 in Turkey and entails the entire universe. Personal information form applied to 752 number of students along with The Child-Adolescent Perfectionism Scale developed by Flett, Hewitt, Boucher, Davidson and Munro (2001) were employed. The results yielded no difference in the self-oriented sub-dimension of perfectionism in terms of gender, having a musician in the family, daily working time and instrument type variables. However, significant differences were observed in the education level and perception of success variables. Referring to the socially prescribed sub-dimension of perfectionism, no significant difference was detected according to daily working time variable. Besides that, significant differences were observed in gender, having a musician in the family, education level, perception of success and instrument type.
