The National Strategic Plan 2009-2012 on HIV and AIDS (NSP) is the result of more than a year of preparatory work, starting with the development of Rwanda's Economic Development and Poverty Reduction Strategy (EDPRS) 2008-2012, which sets out the overarching goals for the response to HIV and AIDS as well as reaffirming Rwanda's commitment to a multi-sector response. In addition, a wide range of analyses carried out in 2007 and 2008 have helped to ensure that the NSP is based on the most up to date understanding of the epidemic, that the strategies are based on evidence of what works in Rwanda and elsewhere, and that the strengths and weaknesses of the systems and mechanisms for responding to HIV and AIDS are addressed through the NSP.
