A study will go forward on the state’s redistribution of money from poorer to wealthier school districts in a funding formula a Volusia County critic called “backwards Robin Hood.” The formula has cost Seminole, Osceola and Lake schools tens of millions in local tax revenue being redirected to more affluent districts, including Orange and Miami-Dade. In the latest fiscal year, 55 school districts sent a portion of their money to just a dozen other districts that have higher costs of living, which drives up the cost of education.
