This study is a review of the training provided in major human rights operations in the 1990s (Haiti, Cambodia, Rwanda, El Salvador, former Yugoslavia, etc). It makes concrete recommendations regarding who should be trained – including management and local staff – in what, when, and by whom. It also highlights the need for distillation of better field practice, systematically fed into organisational learning and ultimately future training. It concludes that in particular the absence of systematic organisational learning remains a major weakness at the heart of international human rights fieldwork.
