Nowadays, adult education is an increasingly actual theme. Given the rapid changes that are taking place, both in the business and personal fields, there is an increasing need for lifelong education and learning for various actors in society. In everyday terms, adult education refers to formal and non-formal adult education. Like every European country, Hungary also bases its education system on certain documents, policies, values and qualifications. In order to gain insight into the educational system in Hungary, which deals with adult education, it is necessary to study the historical course of development of adult education in this country. Following an overview of the development of adult education in Hungary, the areas of adult education in the Hungarian education system are highlighted, followed by key measures that help to involve adults in the educational system. It is clear that without national authorities, legislative legislation is not enforceable, and therefore they are presented in this paper, as are some statistical indicators on the participation of adults in the educational system in Hungary compared to the European average. In order to achieve adult education, it is important to constantly work on the quality of the education system, so the issue of financing adult education is also important. The last part of this thesis presents an analysis of the countries in the surrounding area of Hungary, with statistical indicators of adult involvement in the education system and employment average compared to the national average of Hungary and the average of European countries.
