In a follow-up to a 2005 report showing that charter schools are significantly under-funded compared to district schools, the authors find that little changed over four years, and charter schools receive nearly 20 percent less funding per pupil than district schools. The report, created in collaboration with researchers Meagan Batdorff, Larry Maloney, and Jay May, examines FY 2006-07 data from 24 states and Washington, DC in the most comprehensive analysis of charter funding to date. While Public Impact did not carry out the data-gathering for this edition, the firm’s Daniela Doyle led the writing of the cross-state analysis.
