Abstract
The present study presents adult education institutions and participants in adult education at the national level, highlighting the Borsod-Abaúj-Zemplén County. It shows the decrease in the number of tasks and the change in the types of maintainers, the decreasing trend of the number of privately maintained institutions and the number of students. Thanks to public interventions, private-run institutions have completely shrunk in the last 7 years due to support for training. Private institutions receive little or no state support for the teaching of the professions listed in the National Training Register, which means that students can only study in private schools for a fee. This decision resulted in the dissolution of most privately maintained institutions, their merging into local Vocational Training Centres or church institutions. The main goal of the research was to get a realistic picture of the causes of institutional change.
