This article illustrates the application of the Impact Evaluation Process for the design of a performance measurement and evaluation framework for an urban high school. One of the key aims of this framework is to enhance decision-making by providing timely feedback about the effectiveness of various performance improvement interventions. The framework design process is guided by the Impact Evaluation Process, and included the participation of key stakeholders including administrative and teaching staff who all contributed to the performance measurement and evaluation framework design process. Key performance indicators at the strategic, tactical, and operational levels were derived from the school vision, and linked to specific interventions to facilitate the continuous evaluation and improvement process.
