The achievement of vision of the AEC by 2025 requires effective monitoring of progress and outcomes, hence the development of an enhanced monitoring framework is stipulated in the AEC Blueprint 2025, through the use of appropriate approaches and robust methodology, the monitoring of impact and outcomes, and the support of the ASEAN Community Statistical System (ACSS). The AEC 2025 Monitoring and Evaluation (M&E) Framework ensures the timely and effective implementation of the AEC Blueprint 2025. By also including outcomes monitoring and impact evaluation, the AEC 2025 M&E Framework enhances the previous monitoring system i.e. the AEC 2015 Scorecard, which was limited to compliance monitoring and involved a simple binary (i.e., yes or no) checklist of implementation of measures by the ASEAN Member States.
