A recent initiative by the United Nations Office on Drugs and Crime (UNODC) was the development of an e-learning platform on the Nelson Mandela Rules. While national prison legislation, regulations and standing orders are typically covered, international standards, such as the Nelson Mandela Rules, are rarely addressed in-depth. UNODC’s e-learning course, which is tailored to the needs of prison and corrections officers, is intended to contribute to filling this gap.
