Under the legal powers given to the Chief Inspector, inspectors have the legal right to inspect schools, to observe lessons and to scrutinize evidence. Obstructing an inspector in their work, including denying them access to a school or classroom, is actually a criminal offence. In relation to performance management, the school needs to demonstrate to the inspectors that its performance management systems are rigorous and contribute effectively towards identifying training and development needs. However, inspectors do not have the right to look at the performance management reports of individual teachers. These are confidential. Schools may provide anonymised records to exemplify their performance management system.
