While complexity and diversity generally are perceived positively, they present challenges to youth workers and NGO's. Youth work practitioners often talk about the complex work they are expected to undertake which is often for both, structural and organisational reasons: working to rules and procedures, generating paperwork, focusing on the parts in Youth Work rather that the whole picture (narrowing or limiting service delivery), focusing on outcomes at the expense of processes which is linked with accountability to funding bodies. Where does it leave the youth work practitioners? It creates tensions between the value-based professional attitudes and the need to be economically and technically focused service as civil society spaces in Europe are shrinking. The youth work practitioners do not always feel adequately trained to deal with this complexity, internal and external tensions, particularly in a context of uncertainty and taking risks. Youth work practitioners have to constantly adapt to changing conditions and to keep developing the knowledge and skills needed to navigate within fast changing context of the youth work. Critical Refection is one of the methods that can be used to relieve some of these tensions and to improve the well-being of the youth work practitioners. Critical Reflection provides both: theory and process (framework) that enables youth work practitioners to manage tensions and work complexities effectively, and also helps to articulate the value of knowledge that is generated from the practical experiences. Thus, this project is aiming to demystify a critical reflection model and to proved practical tools to navigate through the fast changing youth work context. The main objectives of this project are: - introducing participants to the 'Four lenses: Critical Reflection Model'; - creating a safe space for practicing how to use the 'Four lenses: Critical Reflection Model'; - participants developing a set of competences needed to implement critical reflection model into 'day to day' youth work practices; - preparing participants to become an advocates for critical reflection within their youth work practices and multipliers of 'Four lenses: Critical Reflection Model'. Following essential policy developments and the introduction of Erasmus+: Youth in Action, the European Training Strategy (ETS) starts to show up on the agenda of the European institutions. If we take a closer look at the 'ETS Competence Model for Trainers' and 'ETS Competence Model for Youth Workers' we find that practitioners ability to reflect critically is embedded within the framework of ETS. By implementing this international training course that is primary focusing on developing youth work practitioners competences to reflect critically we are making links with the European Training Strategy. The two chosen topics of this project are: Youth and Health and Wellbeing (in the context of the youth practitioners mental health). These are the topics that Erasmus+ programm is keen to address. Never less, in the field of Youth, under KA1 the Erasmus+ we find that on of the programs objectives is to supports mobility of youth workers in cooperation with Partner Countries neighboring the EU. As we are looking at strengthening the capacity to work internationally of 11 participating organisations from Partner Countries and neighboring the EU we are also contributing to improving the quality of youth work and its recognition.
