The Australian Council for Educational Research (ACER) is one of the world's leading educational research centres. Since it was established in 1930, ACER has built a strong reputation as a provider of reliable support and expertise to education policymakers and professional practitioners. Each year, ACER is involved in a large number of research projects, covering school education, higher education, the development sector, Indigenous education, early childhood education and vocational, adult and workplace education. Throughout the year ACER continued work on major ongoing projects such as the Organisation for Economic Cooperation and Development (OECD) Programme for International Student Assessment (PISA), OECD Teaching and Learning International Survey (TALIS), International Association for the Evaluation of Educational Achievement (IEA) Trends in International Mathematics and Science Study (TIMSS), IEA International Civic and Citizenship Education Study, South-East Asia Primary Learning Metric (SEA-PLM) and Scottish National Standardised Assessments. Many other consultancies were also conducted for governments and other organisations, both in Australia and other countries. In addition, ACER offers regular assessment services including the Progressive Achievement suite focusing on assessing and monitoring student growth over time and scholarship and selection testing for schools. ACER continues to provide a range of admissions tests for higher education, including the Graduate Medical School Admissions Test (GAMSAT) and the Special Tertiary Admissions Test (STAT). This report describes a selection of ways in which ACER continues to provide data and research evidence to inform efforts to address educational challenges.
