The main descriptor of the qualifications is the Unit of Learning Outcomes (ULOs). Each ULO is coherently constructed and organized in respect to the overall qualification. It outlines in an eligible and understandable way the knowledge, skills and competences to be adopted and allows the discrete assessment and validation of the LOs comprising it through credit points. To fit these basic requirements of EU guidelines for VET Pure-H2O project creates a set of 9 qualifications description relevant to drinking water treatment and sanitation sector targets.

• Occupational qualification description - the ISCO (ESCO) reference
• Learning pathway - a series of narrated LOs, the knowledge part of which is presented as a number of chapters and each chapter covers a specified element of training, with a self-test element at the end. The Learning Pathways (LPs) vary in size and content according to the chosen qualification and EQF reference level.
• Competencies acquired - description of specific activities in respect to knowledge (professional), skills (methodical), wider competences (personal and social) to be gained by the learner upon defined period of training in the frame of the Pure-H2O project.
