Charter schools are tuition free independent public schools considered independent school districts by the state of Minnesota. By law, they are tuition-free, open to any student in the state, and governed and operated jointly by licensed teachers, parents and community members. Charter schools operate on three basic principles: accountability, choice, and autonomy. Charter schools are accountable to improve student learning and remain fiscally solvent. Charter law provides that families should be able to choose what public school is best for their child. Charter school autonomy empowers teachers and parents to realize an educational vision at the school site.
