This article provides a relatively compact, organized overview of the reasons and audiences for assessing teacher performance, followed by a review of various specific methods as actually practiced (mostly in the United States) and evaluating (meta-assessing?) these assessment methods. Despite being described as a "literature review," this reader found it to be more of an overview in general-few specific works of research are discussed. However, this reader will find its references section to be very useful as this project is continued.
