The partnership, ASK, seeked to analyse different methods of assessing and certificating non-formal and informally acquired skills in vocational education and training in the participating regions. The partnership brought together organisations which were already using more or less standardized methods in their training courses. However, they felt their assessment tools and certification process could be improved. Thus the overall aim of the project was to identify possibilities for optimizing existing methods by learning from other partners in Europe.Initially the partnership carried out a survey of the different methods used in partner countries as well as in the participating organisations themselves. Next, there was a comparative study of target groups, tested competences, applied tools, certification procedures, all illustrated with ‘examples of good practice’. Finally, the partnership developed proposals for the improvement of methods and tools. Their findings were published in a report and on the web. An ‘ASK-Navigator’ summarized the proposals and defined effective quality standards.The partner organisations were well aware that was no ready answers beforehand, but that they had the competence to ask the right questions: to ‘ASK’. At the end, the partnership lead to a Transfer Innovation Project ("Scaling New Heights") and made a substantial contribution to the discussion of how to illustrate non-formally and informally acquired skills in Europe.
