Staff Performance Evaluations.

Evaluations generally take two different forms: formative evaluation or summative evaluation. Many policy-makers and researchers call for evaluation not only to hold teachers and administrators responsible for teaching students, but also to provide professional development opportunities, increase leadership capabilities, and improve teacher quality. Performance evaluations may include the following procedures: observation, portfolio assessment, and assessment centers. Successful evaluation procedures can have a large impact on improving schools, as well as addressing issues such as teacher retention and professional isolation.
