During the global socio-economic crisis that has hit almost the entire world, Croatia is also experiencing a large increase in unemployment, which is very much reflected on young educated people with no work experience who find it difficult to find a job. In order to try to reduce unemployment, the Government is adopting a occupational training without entering into an employment relationship measure that gives young people the opportunity to gain work experience in a mentor-led profession. The paper is divided into three parts. The first part of the paper deals with a historical overview of the occurrence of the measure, starting from its beginnings, the preaccession action, and until the end of 2017, when there were significant changes and positive developments. The second part of the paper is related to the legal regulations and the definition of the concept of professional development. The last chapter refers to the evaluation of the measure itself, the satisfaction / dissatisfaction of the beneficiary with the measure, the experience with the mentor. Did the measure lead to a fall in unemployment or did it only further widen the gap. In 2016, there is a change in the conditions of use of the measure, it limits the age of the beneficiaries and thus openly discriminates against persons over 30 years of age who are prevented from further use of vocational training and gaining work experience in the profession. a package of measures was adopted to return internships and introduce training for persons over 30.
