Contemporary education reform movements in the United States have emphasized accountability for student performance. Policy actors serving within the executive branch have arguably gained power in part to provide this accountability function. The present study, in which Ohio and Pennsylvania serve as state case contexts, examines the changing education policy role of executive-level state auditors. Findings indicate their powers have expanded considerably between 2005 and 2017, with expansion attributable to four main factors: the proliferation of brick-and-mortar and online charter schools, auditors' political motivations, auditors' ability to conduct performance audits, and state legislatures' reliance on auditors to provide oversight.
