The Assessment of Student Learning Outcomes was part of the Second Education Development Project, funded by the World Bank. It followed the first round which was carried out three years previously by an Australian organization. The overall aim of the project was to increase access to and completion of, primary education in the poorest districts of the country. The Assessment of Student Learning Outcomes measured the extent to which this was achieved. The target population was a nationally representative sample of Grade 5 students in three subjects: Lao Language, World Around Us (Science), and Mathematics.
