The International Development Evaluation Association (IDEAS) was inaugurated in September 2002 to meet the need for a global professional association for internationally active development evaluators. Over the years, much has changed in the global evaluation community. Many new national and regional associations and networks have been created and play a progressively stronger role. Global partnerships and communities of practice have been formed, allowing joint efforts between both evaluation professional associations and organisations. The changing agenda from the Millennium Development Goals to Sustainable Development Goals, the Paris Agreement on Climate Change, the Coronavirus pandemic and the rapidly changing landscape of financing for development pose major challenges. Within this renovated context, IDEAS positions itself as the only global professional evaluation association which focuses on international sustainable development. Over the years it remains the only home for evaluators working globally and on global issues, with a global perspective. It is deeply involved in strengthening and promoting the profession, fostering capacity development, and improving and advancing evaluation theories and practice, methods and use of evidence.
