Public schools can use the Bible in public schools as an academic text, and students and staff keep personal religious rights on campus, but the school itself cannot sponsor devotional Bible reading, prayer, or worship. That line, drawn by the Supreme Court in 1963 and reinforced since, is what every rule below turns on.
Academic Study Is Allowed; Devotional Use Is Not
The foundational case is Abington School District v. Schempp. Pennsylvania required students to hear at least ten Bible verses read aloud at the start of each school day, and the Court struck the practice down 8–1 as a violation of the Establishment Clause.1Justia. Abington School District v Schempp, 374 US 203 (1963) The ruling did not exile the Bible from the classroom. The Court wrote that “one’s education is not complete without a study of comparative religion or the history of religion and its relationship to the advancement of civilization.” Worship on one side of the line, education on the other.
In practice, that means a teacher can assign the Bible the way any other historically influential text gets assigned. Tracing biblical allusions through Milton or Shakespeare, examining how the Ten Commandments shaped Western legal traditions, or comparing biblical texts to the Dead Sea Scrolls all sit on the academic side. The instruction has to be objective and descriptive. Students are graded on their understanding of the material, not on whether they accept it as spiritual truth. A history lesson steered toward a faith-based message crosses the line; a literary analysis of the same passage does not.
The constitutional test courts apply has shifted. In Kennedy v. Bremerton School District, the Supreme Court said it had “long ago abandoned” the old three-prong Lemon test and instructed lower courts to read the Establishment Clause “by reference to historical practices and understandings.”2Justia. Kennedy v Bremerton School District, 597 US (2022) The core prohibition on state-sponsored worship still holds, but arguments rooted in historical tradition carry more weight than they did a decade ago.
Elective Bible Courses
At least seven states require public high schools to offer elective courses on the Bible. Every state law authorizing them imposes similar guardrails: instruction must be nondevotional, cannot teach religious doctrine or sectarian interpretation, and cannot present biblical accounts as literal historical fact. Students should encounter critical perspectives and diverse interpretive traditions rather than a single theological viewpoint. A district that cannot maintain those boundaries is better off not offering the course, because a devotional elective dressed up as academics is the kind of thing that draws lawsuits.
What Students Are Allowed to Do
Students do not surrender their religious identity at the school entrance. A student can read the Bible during lunch, between classes, or any other non-instructional time, just as they could read any other book. Private religious activity is protected as long as it does not disrupt the educational environment or infringe on other students’ rights.
When a teacher assigns an essay, art project, or presentation with an open-ended theme, a student can include biblical references or religious perspectives. Federal guidance from the Department of Education states that such work “should be judged by ordinary academic standards of substance and relevance” and that schools may not discriminate against a student’s submission based on its religious viewpoint.3U.S. Department of Education. Guidance on Constitutionally Protected Prayer and Religious Expression in Public Elementary and Secondary Schools A well-structured essay connecting a biblical parable to a novel’s themes gets graded on the analysis, not on the religious content.
Bible Clubs and After-Hours Access
The Equal Access Act requires any public secondary school that receives federal funding and allows non-curriculum student groups to meet on campus to extend the same access to religious groups.4Office of the Law Revision Counsel. 20 USC Chapter 52 – Equal Access A school that permits a chess club or environmental group to meet during non-instructional time cannot refuse a student Bible study on the same terms. The groups must be student-initiated and student-led, and any faculty advisor serves in a non-participatory supervisory role. The school is not endorsing the group’s message; it is providing equal access to its facilities.
The same principle governs outside groups after the school day. In Good News Club v. Milford Central School, the Supreme Court held that a district violated the Free Speech Clause when it excluded a private religious group from meeting in school facilities after hours while allowing other community organizations to use the same space.5Justia. Good News Club v Milford Central School, 533 US 98 (2001) Denying access based on religious viewpoint is viewpoint discrimination.
What Teachers Cannot Do, and What They Still Can
Teachers occupy a narrower space than students. As government employees acting in their official capacity, they cannot lead prayer, encourage devotional Bible reading, or steer students toward or away from any religious belief. The Constitution treats a teacher standing in front of a class as the state speaking, and the state cannot promote religion.
Personal time looks different. Teachers can pray privately, read their own Bible, or meet with colleagues for a prayer group before school or during lunch, just as they could make a personal call during those times.3U.S. Department of Education. Guidance on Constitutionally Protected Prayer and Religious Expression in Public Elementary and Secondary Schools The dividing factor is context. A teacher bowing their head silently at their desk before students arrive is exercising a personal right. The same teacher leading the class in a group prayer five minutes later has crossed into establishment. Districts that try to prohibit all teacher religious activity, even during genuinely personal time, risk violating the Free Exercise Clause in the other direction.
Parents’ Right to Opt Their Children Out
In Mahmoud v. Taylor, the Supreme Court strengthened parental rights to opt children out of classroom instruction that conflicts with sincerely held religious beliefs. The case involved parents who objected to certain storybooks introduced into the curriculum, and the Court ruled that the district had to give advance notice of the materials and allow parents to have their children excused.6Supreme Court of the United States. Mahmoud v Taylor, No 24-297 (2025)
The reach goes beyond the specific books at issue. Any school running Bible-related instruction, whether under a state mandate or a locally designed curriculum, should expect that parents who object on religious grounds have a constitutionally grounded right to remove their children from those lessons. The 2026 Department of Education guidance incorporates Mahmoud and advises districts to proactively adopt opt-out policies for any lesson that could substantially interfere with a family’s religious development.
Release Time for Off-Campus Religious Instruction
Public schools can release students during the school day for religious instruction conducted off campus. The Supreme Court upheld this arrangement in Zorach v. Clauson, distinguishing it from programs that bring religious instructors into the school building.7Justia. Zorach v Clauson, 343 US 306 (1952) Adjusting the schedule so students can leave campus for religious education is accommodation; using school classrooms for religious teaching is entanglement.
Programs typically run one to five hours per week. Participation must be voluntary, parents must give written consent, students who do not participate cannot be penalized, and the instruction has to happen entirely off school grounds with no public funds supporting it.
Recent State Mandates
Several states have recently pushed the Bible into a more prominent classroom role, and the resulting litigation shows how contested this ground remains.
In 2024, Oklahoma’s Superintendent of Public Instruction issued a memorandum directing all public schools to incorporate the Bible and the Ten Commandments into curricula for grades five through twelve and to keep physical copies in every classroom. The directive drew immediate legal challenges. By late 2025, the Oklahoma Supreme Court dismissed the lawsuit as moot after the policies were rescinded and nullified, ending that mandate without a ruling on its constitutionality.
Louisiana took a different approach the same year, passing legislation requiring every public classroom from kindergarten through the university level to display the Ten Commandments on a poster or framed document of specified size and font. Schools are not required to spend their own funds; they must accept donated displays or donated funds to purchase them. A federal district court initially blocked the law with a preliminary injunction. In February 2026, the Fifth Circuit vacated that injunction on procedural grounds, finding the challenge premature because the displays had not yet been posted in the plaintiffs’ classrooms. The litigation continues, and the law’s constitutionality remains unresolved.
Both efforts frame the Bible and the Ten Commandments as historical documents essential to understanding American law and culture. Whether courts accept that framing under the historical-practices standard from Kennedy will likely define the next round of this debate.
The Federal Prayer Certification Tied to Funding
Federal law ties education funding to a specific religious-expression obligation. Under 20 U.S.C. § 7904, every school district that receives funds under the Elementary and Secondary Education Act must certify in writing to its state education agency, by October 1 each year, that it has no policy preventing or denying participation in constitutionally protected prayer.8Office of the Law Revision Counsel. 20 USC 7904 – School Prayer The state agency then reports any noncompliant districts to the U.S. Secretary of Education by November 1. Districts that fail to certify, or that certify in bad faith, face enforcement from the Department of Education, which can include withholding federal funds.
The requirement cuts both ways. A district that bans student-led prayer groups violates it just as much as one that imposes mandatory devotional readings. Schools have to protect constitutionally permitted religious expression without sponsoring it. The Department issued updated guidance in February 2026 reflecting the Kennedy and Mahmoud decisions, superseding earlier guidance from 2023.3U.S. Department of Education.

What It Costs a District to Get This Wrong
Districts that cross the line face real financial exposure. Under 42 U.S.C. § 1988, a court can award attorney fees to the prevailing party in civil rights cases, including Establishment Clause challenges.9Office of the Law Revision Counsel. 42 US Code 1988 – Proceedings in Vindication of Civil Rights Defending an unconstitutional Bible mandate or devotional practice can cost a district hundreds of thousands of dollars in legal fees alone, drawn from budgets meant for classrooms and teachers. Courts can also issue injunctions requiring immediate removal of materials or cessation of practices. In rare cases, individual school officials who knowingly violate clearly established constitutional rights may face personal liability, though most of the financial pain falls on the district as an institution.
