We outline a multidimensional ecological systems policy framework to better understand how the Individuals with Disabilities Education Act (IDEA) and patterns of racial disproportionality in special education relate. The framework engages with ideology, power, privilege, and context across the multiple layers of the policy-implementation process and educational ecosystem. It highlights how policy reverberates through the educational ecosystem via interpretation and implementation flows spanning from the exo-, macro-, and meso levels (e.g., federal policy, state education agency (SEA) guidance, local education agency (LEA) officials' actions, educators) to the micro- level (e.g., families and students) and back up. The framework provides critical insights that can inform efforts to reduce racial and ability inequities.
