In this study, the authors focus on one highly contested provision of the No Child Left Behind Act, which allows states flexibility in how the quality of teachers is defined and evaluated: the high, objective, uniform state standard of evaluation (HOUSSE) option. The authors conducted a national survey of representatives from each state to explore how HOUSSE is being interpreted for secondary special education teachers. Findings indicate that significant variability in the interpretation and implementation of the HOUSSE provision exists across states and that numerous challenges with the implementation of federal teacher quality requirements persist and difficulties with holding districts accountable for teacher quality provisions.
