The Australian NGO Cooperation Program (ANCP) is an annual grants program that provides matched funding to accredited Australian NGOs to support their work in developing countries. Funding supports projects across a range of sectors including education, health, water and sanitation, governance and economic development. Established in 1974, the ANCP is DFAT’s (and formerly AusAID’s) longest running NGO program. It also represents the largest program for Australian NGOs, with a 2014 –15 allocation of $134 million constituting approximately one-fifth of all funding provided to NGOs and 2.7 per cent of Australia’s Official Development Assistance budget. As a large global program, ANCP activities span multiple countries and regions with individual projects numbering in the hundreds. Assessing the impact of the ANCP on individuals and communities in developing countries across the globe was beyond the scope of the evaluation. Rather,the Office of Development Effectiveness set out to assess the effectiveness of the ANCP as a mechanism to assist NGOs in reducing poverty and supporting sustainable development. The evaluation confirmed that the ANCP is a successful and highly valued program. It identifies positive features which might usefully inform the Australian Government’s approach to a number of other development programs and partnerships. However it also highlights areas for improvement, such as the need to address the complexity and limited transparency associated with funding allocations and the opportunities for greater sharing of knowledge and learning across the partnership.
