The objective is to present training on the International Classification of Functioning, Disability and Health (ICF) prepared by the Disability Italian Network (DIN) and to present strategies of ICF dissemination in Italy. A description of DIN's training methodology, prepared in collaboration with World Health Organization (WHO) experts, is provided within its practical applications in health, labour, rehabilitation and statistical sectors. The ICF-DIN Basic Course is eight hours long and focuses on ICF basic principles, structure and application in different settings. The ICF-DIN Advanced Course, three days long followed by three months of distance learning, assumes Basic Course completion, and focuses also on ICF-checklist's coding and WHO-DAS II administration. The first training courses' outcomes, held in Italy and addressed to health, social and labour professionals, are provided. The feedback received by participants at the end of the courses showed that the main mistake they made was to consider ICF as an assessment instrument. The ICF-DIN training course was crucial in explaining the correct use of the ICF as a classification and to show its impact and usefulness on daily practice, particularly in multidisciplinary teams. The ICF-DIN courses already carried out in Italy show that this teaching methodology teaches how to avoid incomplete applications, simplification and misunderstanding of ICF's complexity.
