Normally, during a lesson observation, inspectors will stay for a reasonable length of time to gather the evidence they require. In primary schools, they often stay for a session (for example from mid-morning break to lunchtime). In secondary schools, they are likely to stay for the whole lesson. However, inspectors may also observe teaching and learning in other ways, for example by undertaking ‘learning walks’ through a number of classes. In these instances, the amount of time in the classrtoom may be short as the inspector focuses on just one or two aspects of provision. The inspection team is likely to use a mix of these approaches.
