The six-step school self-evaluation process involves gathering evidence, analyzing it using evaluation criteria, drawing conclusions by benchmarking against quality statements, producing a self-evaluation report, creating an improvement plan with targets and actions, and implementing and monitoring the plan. Key steps include collecting data from various tools, analyzing the data on themes of teaching and learning, learners' outcomes and experience, and teachers' practice, and using the analysis to identify strengths and areas for improvement to guide school-level actions.
