This note is concerned with the development of a process to analyse how assessment practices are integrated into education systems in order for assessment outcomes to be useful for evidence based decision making throughout the system. It examines the quality of learning assessment and the extent to which it is embedded into an education system and acts as an effective contributor to the improvement of learning outcomes. The process is referred to as the System-Wide Analysis of Assessment Practices (SWAAP). The primary objective of SWAAP is to support education systems to develop national assessment strategies that generate meaningful data and assist the systems with the improvement of learning outcomes
