The purpose of the study is to analyze students’ high demands on themselves and others; the desire to achieve sophistication in everything (especially in work) – perfectionism. Two methods of the research were used: theoretical analysis and diagnostic tests: “The Multidimensional Perfectionism Scale” by P. Hewitt and G. Flatt, one for determining the level of self-efficacy by M. Scheer and J. Maddux in the adaptation of A. V. Boyarintseva, the methodology “Differential test of perfectionism by A.A. Zolotareva”. The students of Sevastopol State University took part in the surveys. The empirical study involved 30 people (students - future environmental engineers). When studying the features of perfectionism, according to the results of the methodology «Multidimensional scale of perfectionism», the levels of perfectionism were equally distributed, namely, half of the sample had low indicators of perfectionism, and the other half had average ones. The results according to the method of A. Zolotareva aimed at studying perfectionism among students show that most of the respondents have a normal type of perfectionism, that is, such students tend to strive for excellence without conflict with other motives.A relationship between personal maturity and perfectionism among students was identified by means of the Pearson correlation coefficient. Recommendations for increasing the level of perfectionism to a constructive one were given due to theoretical analysis and empirical study of the problem of personal maturity and perfectionism among students. In conclusion the authors consider the training program as an integrative personal education, consisting of researching indicators: personal, cognitive-activity, and social components.
