(June 2011) DDR Practitioners gather in Montreux for advanced Training of Trainers - June 2011, Montreux, Switzerland. At UNITAR’s Peacekeeping Training Programme, training is seen as a conduit for transformation—leading individuals to make changes that improve and enhance their performance at work and in life. In particular, “training of trainers” (ToT) is a concept which aims to give individuals the skills and knowledge to implement an adult training programme on a given topic. A training of trainers thus teaches practical exercises for engaging and delivering material to participants to maximize learning.
