The purpose of this study is to explore the efficacy and sustainability of the outcomes from vocational training delivered in DDR programs pertaining to (i) issues related to the design and implementation of vocation¬al training and activities, and (ii) issues relating to the external economic and social environment as well as the history and profile of ex-combatants who have un¬dergone vocational training. The outcomes of this study will help develop learning which can inform: (i) future vocational training programming in DDR and stabiliza¬tion programs, and (ii) areas of learning which might benefit from additional analysis or investigation. The study provides learning that can be translated into (i) general principles regarding the success of DDR vocational training, and (ii) considerations to inform future DDR vocational training programming in other countries. Through this study, the Transitional De¬mobilization and Reintegration Program (TDRP) is expected to more accurately gauge the influencers on effectiveness and sustainability of DDR vocational training as well as inform the design of future vocational training programs and skills development-related stabi¬lization interventions.
