The Heureka Generator Association, before receiving accreditation in the 'Youth' field, carried out individual projects under the Erasmus+ program (‘Youth’ sector). The implementation of these projects was significantly different from the activities we undertake under accreditation. The fundamental difference lies in the fact that accreditation allows us to plan long-term activities. Thanks to accreditation, we can plan a calendar for several months and be sure that the youth who start cooperating with us will have further opportunities for international development. Up until now, the long periods between our projects were filled by the participation of youth in outbound projects organized by our partners. However, participating in our partners' youth exchanges is not comparable to the opportunities for youth engagement that we provide at every stage of our projects. Both of these options are valuable, but the implementation of our project offers youth much greater chances of involvement at every stage. The period from writing the project together with the youth, through its acceptance, followed by implementation and dissemination activities, typically takes a year, and sometimes even longer. After the project activities are completed, youth would like to continue actively working and creating new projects with us. Unfortunately, the period from the inception of an idea to the realization (if accepted) of a project is so long that we often couldn't guarantee the cooperating youth the continuation of activities in a relatively short time. The accreditation system has changed that. Through project implementation, we have achieved a valuable result, which is the continuity of activities with partners and youth. Partners and youth worked with us during one activity and then received a guarantee of further development or cooperation during subsequent activities. We no longer had to tell participants that we might meet again if our next project based on their idea is accepted. We simply presented the next stage of our joint activities. This resulted in participants' involvement in subsequent activities under our accreditation at a deeper level. Of course, we also carry out local activities where our youth are actively engaged, but accreditation provided Polish active young people with the opportunity to meet again with people from other countries they had already met during exchanges, as well as engage in further joint activities and exchange experiences. A boy from Lithuania, after the first exchange, became an assistant group leader in the next one. Leaders from Romania utilized the knowledge gained during the exchange and training course, which resulted in a youth exchange in Romania. We were able to offer local partners at least 3-4 years of cooperation and long-term engagement of youth. Our Polish and foreign experts in non-formal education methods, which we promote, could engage in our certain, well-planned activities on a long-term basis. There are many more examples like these. Stability and long-term actions were our primary goal, and we have successfully achieved that.
