In 2012, the Ministry of Education, Afghanistan, engaged the Australian Council for Educational Research (ACER) as a partner to support the development of a national learning assessment program in Afghanistan. To achieve this goal, the Learning Assessment unit of the Ministry of Education and ACER have collaborated to design and implement the Monitoring Trends in Educational Growth (MTEG) program in Afghanistan. MTEG is designed as a long-term monitoring program with one focus on trends in achievement outcomes in single class levels over time, and another focus on the growth of achievement in cohorts throughout the school cycle, from Class 3 through to Class 9. This paper presents the results of an assessment of mathematical, reading and writing literacy of Class 6 students in 13 provinces in Afghanistan, based on data collected in late 2013.
