In this article, I draw on my experiences as a Teaching Practice Observer for various Colleges of Further Education and Adult Education establishments across South West England from 1994-2002. I discuss the essential lesson components that observers need to attend to when evaluating candidates. These include the candidate's diversity of teaching styles, communication skills, and engagement with students, combined with an adequate knowledge of the subject matter. Equally important is an evaluation of the written material given to the observer prior to the lesson. I highlight the importance of an observation protocol and providing opportunities for feedback from both peers and a trained observer.
