The European Training Strategy (ETS) of the European Commission outlines findings, objective, and Measures to sustain the quality and recognition of youth work in Europe . It was introduced as part of the European Union’s YOUTH program (2000-2006) and is revised regularly.  The most recent version adapted to Erasmus + , covering the time period between 2014 and 2020.  
The current version of the ETS is closely associated with a 2009 resolution by the Council of the European Union which describes the “renewed framework for European cooperation in the youth field”.  Based on several recommendations, the ETS determines the concept of capacity building as a key instrument to address the multifaceted aspects of youth work.  In the context of the ETS, capacity building is defined adhering to the three analytical levels of analysis .  
- Micro-level – Human resource development : Strategies and measures to equip individuals working in youth work as employees, freelancers or volunteers with five professional skills (knowledge, skills, attitudes) and access to information .
- Meso-level – Organizational development : The elaboration of awareness, strategies, processes and procedures within a youth work organization (public, private, and community).
- Macro-level – Systemic framework development : Making regulatory changes or creating systems and structures to enable organizations, institutions, and agencies at all levels to improve their capacities.
Incorporating its initial definition of capacity building, the ETS outlines six main objectives for sustainability. Each objective is to be implemented under different Key Actions within Erasmus +. Key Actions: Key Actions and Key Activities: Key Action 2: Key Action 2: Key Action 2 Reform (Key Action 3). 
The ETS pursues the following objectives   
- Encourages cooperation between the different stakeholders throughout Europe.
- Generate more knowledge about capacity building and its impact on youth work.
- Develop a modular system and a set of skills to train trainers.
- Develop a modular system and a set of skills to train youth workers.
