Is busing of students to parochial schools constitutional or unconstitutional?

The busing of students to parochial schools can be constitutional, provided that the transportation is offered in a neutral manner and does not promote religious instruction. The U.S. Supreme Court has upheld that public funds can be used for transportation to religious schools as long as the program benefits all students equally, regardless of the school they attend. However, specific cases and state constitutions may impose additional restrictions, so the constitutionality can vary based on context.
