The American Historical Association signed onto the American Sociological Association's Statement on Teaching Evaluations. While acknowledging the valuable feedback that student experiences in the classroom can provide, the statement discourages the use of such assessments as a primary factor in faculty promotion, salary increase, and appointment. Studies have shown that student evaluations of teaching are easily biased, particularly towards women and minorities, and weakly related to other measures of teaching effectiveness and learning outcomes. The ASA also provides recommendations of best practices for future collection and implementation of student feedback.
