This document introduces the Common Assessment Framework (CAF), a self-assessment tool developed by the EU for public services to evaluate their performance. It describes the CAF model which examines an organization's leadership, strategy, people, partnerships, processes, and results. The CAF uses a plan-do-check-act cycle and involves establishing an assessment group to score the organization's performance in each area. The results are then used to identify priorities for improvement and develop an action plan to enhance the quality of public services.
