ISI inspections are rooted in the principle of peer review to support holistic school development and improvement. This course addresses the structure of Second Cycle inspections, introduced in September 2005, making clear where the changes lie. It traces the steps that need to be taken to ensure that the evidence base that the school provides for the inspectors is accurate, thorough and readily accessible. The pivotal importance of effective school self-evaluation will be highlighted, as it lies at the heart of a good school, directly reflecting the quality of leadership and management. Far from being a daunting prospect for a school, the inspection process offers an unrivalled opportunity to celebrate strengths and achievements. The secret is in the preparation.
