Most evaluation systems rely at least in part on principals’ assessments of teachers, and their discretionary judgments carry substantial weight. However, we know relatively little about what they value when determining evaluations and high stakes personnel decisions.

ABSTRACT Value-added models (VAMs) of student test scores are used within education because they are supposed to measure school and teacher effectiveness well. Much research has compared VAM estimates for different models, with different measures (e.g., observation ratings), and in experimental designs. VAMs are considered here from the perspective of graphical models and situations are identified that are problematic for VAMs. If the previous test scores are influenced by variables that also influence the true effectiveness of the school/teacher… Continue Reading
