Final answer:
Constitutional criticism of tuition vouchers often centers on the establishment clause of the First Amendment, with concerns that vouchers could use public funds to support religious schools, which the Supreme Court has addressed in Zelman v. Simmons-Harris.
Step-by-step explanation:
An example of a constitutional criticism of tuition vouchers is c) they violate the establishment clause of the first amendment because tax dollars go to support religious schools. This criticism stems from concerns that such vouchers may use public funds for religious education, potentially breaching the separation of church and state. The U.S. Supreme Court addressed this issue in Zelman v. Simmons-Harris, ruling that as long as the voucher program is neutral toward religion and provides parents with genuine choice among options secular and religious, the program does not violate the Establishment Clause. Proponents argue that not providing vouchers can limit parental choice and thus freedom of religion, while opponents see it as governmental endorsement of religious education.
