most scholarships to parochial schools are local or diocesan. Sometimes parishes, particularly those with strong tithing programs, offer tuition assistance for their own or surrounding area Catholic schools. Many dioceses offer scholarships as well. In both Cleveland and Detroit there was a test given to 8th graders as an entrance exam and scholarship qualifying test for Catholic high schools. Other Catholic orgs like Knights or Catholic daughters may also offer scholarships, try your diocesan office of education for referrals. There may also be programs for minorities, migrants, native Americans etc, depending on your diocese.
