Drawing on longitudinal data of state K--12 education policymaker demographics, we examine education policymaking body diversity over time, and across states and institutional structures. Though dominated by white businessmen, females and professional educators increased their presence at the education policymaking table. There was little movement in representation of policymakers of color. Institutional structures such as election type and professionalism were related to greater representation of females and persons of color in state education policymaking bodies.
