The statement "The only thing that is constant is change" is an apt description of state accountability systems over the past few years. With the passage of the Every Student Succeeds Act (ESSA), many states have significantly refined their existing school accountability systems or completely redesigned new systems in recent years. The goal of this brief is to describe a logical framework and practical recommendations for states as they wrestle with the continuing demands on their accountability outcomes despite substantial changes to their educational systems. A systematic approach is provided to diagnosing the potential effects a change to a state's assessment or accountability system could have on accountability outcomes. Also provided us practical advice for states as they consider additional changes to their systems. It is the authors' hope that the framework and recommendations described in this brief can helps states establish a sustainable approach or pathway as they navigate through the sea of constant change.
