Does the nation's largest school voucher program violate the Indiana Constitution?
Members of the Indiana State Teachers Association say it does, and now it is up to the Indiana Supreme court to decide.
Opponents claim the program violates a state constitutional ban on government support of churches because it compels taxpayers to pay for schools that teach religion.
But the Indiana Attorney General's office says parents are free to send their students to any school they want.
Arguments are set to begin on November 21st.
