The National AIDS Spending Assessment (NASA) (2010-2012) is the third effort to track all the HIV/AIDS spending in Zambia from all sources (excluding out-of-pocket) and across all sectors. The first NASA was undertaken for the years 2005 and 2006. For the years 2007 to 2009, the Public Expenditure Tracking (PETS) approach was applied1. The NASA provides an in depth examination of the HIV/AIDS by detailed categories of activities, providers of services and the beneficiaries. NASA applies a standardised and comprehensive methodology for collecting, coding and analysing of HIV expenditure. It allows countries to understand if they are allocating funds according to their priorities and for the greatest investment in terms of impact.
