Which technique is NOT commonly used to evaluate teacher performance?

Community surveys are not a commonly used technique to evaluate teacher performance because traditional evaluation methods focus primarily on direct interactions and professional assessments within the educational setting. Teachers are typically evaluated through methods such as classroom observations, where administrators or peers observe teaching practices directly in the classroom. This allows for an assessment of instructional methods, classroom management, and student engagement.

Self-assessments provide teachers an opportunity to reflect on their teaching practices and identify areas for improvement, contributing to their professional development. Peer reviews involve evaluations by fellow educators, which can offer valuable insights into teaching effectiveness through collaborative feedback.

While community surveys can gather feedback from parents and community members regarding a school's impact and reputation, they do not offer a nuanced review of individual teacher performance in a way that directly informs pedagogical practices. Therefore, community surveys are less effective and less commonly employed for evaluating teachers compared to more direct and formal evaluation techniques.
