We are currently witnessing the return to self-employment. The development of individual entrepreneurship is, among others, the result of transition to services and changes in the character and organization of work. This paper underscores the fact that the Polish vocational education system spares no efforts on adaptation to the existing conditions so that vocational school graduates could have better prospects for employment. Hence, transformations in the field of vocational education were also to be made in accordance with the following principle – vocational mobility, understood as the ability to look for employment not only in other companies, but also try to be self-employed. The problem of sole proprietorship has been analysed on basis of the results comprised in the following study: „The preparation of students to flexible forms of employment and work organization”.The study was financed with educational funds covering the years 2009 – 2010 as an academic research promoter project.
