ILSA Gateway

The ILSA Gateway provides easy access not only to IEA studies but also to major International Large-Scale Assessments (ILSA) conducted by other organizations, including, but not limited to, the Conference of the Ministers of Education of French-Speaking Countries (CONFEMEN), the Inter-American Development Bank (IDB), the Organisation for Economic Co-operation and Development (OECD), the Southern and Eastern Africa Consortium for Monitoring Educational Quality (SACMEQ), and the United Nations Organization for Education, Science and Culture (UNESCO).

The Gateway was created to meet the needs of researchers, policymakers, and decision-makers, as well as officials and staff members from intergovernmental, international nongovernmental, and civil society organizations. It aspires to enhance the exchange of knowledge, to encourage secondary analyses of data, and to strengthen communication within the ILSA community.
