Advanced Training for Trainers in Europe (ATTE) is a part-time training programme for trainers active in training youth multipliers. ATTE has been designed in order to meet the increasing need for qualified youth trainers and to enlarge and further develop the European networks of trainers who have the competence and the motivation to develop and implement European level training activities in the youth field. The training programme follows the philosophy of non-formal education and seeks to extend and deepen the European practice of (youth) training in non-formal education.ATTE was implemented successfully as a pilot course between November 2001 and October 2003, involving 30 participant trainers from 21 countries. Some 1 000 youth workers and youth leaders from all over Europe participated in the 26 practical training projects organised by the participant trainers during two practice periods.Bringing together a wide spectrum of educational expertise and experience, integrating good practices, and developing from it a new concept with a larger dimension than that of existing practices, ATTE is new and innovative in its approach, methodology, structure, long-term perspective and intensity, it is a step further in quality European level training of youth workers and youth leaders and towards the recognition and certification of training for trainers in the field of non-formal education.
