The purpose of the study was to examine teachers’ satisfaction with their professional activities. 272 teachers who have classes in physical education and sport in the Bulgarian school system participated in the research study. The teachers have different levels of professional qualification. A modified questionnaire was applied, with 22 items related to the satisfaction with the teaching profession. The statistical methods used for the research were: variance analysis, factor analysis (principal component analysis), non-parametric Mann-Whitney and Kruskal-Wallis tests. The following four factors related to the satisfaction of the profession were identified: organization and professional environment, social working conditions, reforms in education, education and personal development. The items with highest values were: the duration of holidays, professional relations with colleagues, professional relations with the school management, and professional relations with parents. The items with lowest values were: the amount of the salary, the professional relations with the Ministry of education and science, the prestige of the profession, and the reforms in education. Factors related to the internal educational environment have the greatest impact on the satisfaction of the surveyed teachers. UDC Classification: 617.7, DOI: 10.12955/cbup. v7. 1400
