The American Educational Research Association became the latest organization to caution against using value-added models — complex algorithms that attempt to measure a teacher’s impact on student test scores — to evaluate teachers and principals.
A growing number of states have begun using value-added models, or VAMs, to judge and in some cases fire teachers. But there are still a lot of unanswered questions about how to ensure that such models provide valid, reliable and accurate information about teachers, AERA said in a statementreleased Wednesday.
AERA cautioned against using these formulas for “high-stakes decisions” about educators.
“Many states and districts have incorporated VAM in a comprehensive system to evaluate teachers, principals, and educator preparation programs,” the statement says. “There are considerable risks of misclassification and misinterpretation in the use of VAM to inform these evaluations.”
