This document summarizes the legal framework around religion in public schools according to court rulings and legislation. It discusses key Supreme Court cases that established religion cannot be established by law and there must be separation of church and state, but that individuals have the right to free exercise of religion. It also examines contemporary issues in Texas schools around topics like school prayer, wearing religious symbols, and student religious groups having equal access to facilities. The goal across rulings is for schools to maintain religious neutrality while protecting individual religious freedom and expression.
