Toni Waggoner discusses her work on public school financing during her long tenure at the Illinois State Board of Education from 1979 to 2010. She explains the functioning of the state's school funding formula and the role of the Education Funding Advisory Board (EFAB). Toni explains why a disparity grew between rich and poor school districts, and Illinois public schools' growing dependency on property taxes, providing the vast majority of revenue. She also discussed the role of Average Daily Attendance (ADA), local property wealth, Property Tax Extension Limitation Law (PTELL), Corporate Personal Property, the Foundation Level, and the Poverty grant. All of these impacted the amount of state funds given to a local public school district.
