AME 255 Assessment, Monitoring, and Evaluation is a 4-hour self-paced online training (OLT) course that will prepare security cooperation practitioners (program managers, analysts, field implementers, policy makers, etc.) to systematically design, implement, and utilize assessment, monitoring, and evaluation systems that advance national security objectives through evidence-based program management. This course will enable practitioners to transform security cooperation activities into measurable outcomes by establishing clear theories of change, implementing robust performance monitoring plans with appropriate indicators, and conducting rigorous evaluations that generate actionable insights for strategic decision-making and organizational learning.
