This brief summarizes the activities and outputs achieved by Teaching and Learning: Educators' Network for Transformation (TALENT) and Network on Education Quality Monitoring in the Asia-Pacific (NEQMAP) through the Assessment for Learning (A4L) initiative's support and analyzes the outcomes to which this support has contributed and how this is situated vis-à-vis GPE's broader support to strengthening learning assessment systems. The brief has benefited from the findings of an independent summative evaluation of A4L. One of the evaluation's recommendations is that GPE should amplify the research and knowledge products generated by the networks, and this brief is produced in that spirit.
