For the 2011-12 school year budgets, 247 school districts adopted a resolution certifying that tax rates would not be increased above their index; 250 school districts adopted a preliminary budget. Of the 250 school districts that adopted a preliminary budget, 231 adopted real estate tax rates that exceeded their index. Tax rate increases in the other 19 school districts that adopted a preliminary budget did not exceed the school district's index. Of the districts who sought exceptions 221 used the pension costs exemption and 171 sought a Special Education costs exemption. Only one school district sought an exemption for Nonacademic School Construction Project, while one sought an exception for Electoral debt for school construction. With the 2011 state education budget, the General Assembly repealed most of the Act 1 tax increase exceptions leaving only special education costs, pension costs and prior voter approved (ballot referendum) debt for construction. The cost of construction projects in the future will go to the voters for approval via ballot referendum. Additionally, public school districts can no longer raise property taxes to cover increasing health insurance costs for employees.
