The legal source matters. The federal Religious Freedom Restoration Act generally requires the federal government to justify a substantial burden on religious exercise under a compelling-interest, least-restrictive-means test. State statutes and constitutions may add protection against state and local rules. A correct result can therefore rest on statutory law even when the Free Exercise Clause alone would not require it.

Mahmoud v. Taylor (2025) illustrates the modern constitutional analysis. Parents sought advance notice and an opt-out from specified elementary-school instruction that conflicted with their religious beliefs. At the preliminary-injunction stage, the Court concluded that the combination of mandatory instruction and the denial of notice and opt-outs posed a very real threat of undermining those beliefs. The school board had not satisfied strict scrutiny on the record before the Court. The holding does not create a universal parental veto over curriculum; it concerns the demonstrated religious burden, the no-opt-out policy, and the request for interim relief.

Accommodating religion is not automatically establishment. Government often has room to lift a burden without endorsing a belief, though an accommodation must still be assessed in context. For an exam scenario, identify the burden, test neutrality and general applicability, compare secular exceptions carefully, and determine whether the claimed protection comes from the Constitution, RFRA, or state law.
