Public schools are allowed to teach students about religion. But when does teaching about a religion become encouraging students to participate in it? That question is the focus of a new federal lawsuit against the Palo Alto Unified School District in California.
In fall 2025, students in Palo Alto High School's Social Justice Pathway, an interdisciplinary program focused on social justice issues, took a school-sponsored field trip to the Muslim Community Association mosque in Santa Clara. According to the lawsuit, students observed Dhuhr, the Muslim midday prayer, listened to Quran recitations, received Qurans, and were encouraged to wear Islamic religious clothing, including hijabs for female students. The plaintiffs also allege that the program presented Islam more favorably than other religions. The lawsuit was filed on August 7, 2026, by a group of parents and students against the school district and Palo Alto High School principal Brent Kline. Because the case is still at an early stage, these allegations have not been proven in court.
People who participated in the trip have disputed the idea that it was religious instruction rather than education. At least one student who attended has said she did not feel pressured to participate in or adopt Islamic religious practices. That disagreement matters because the constitutional issue is not whether public schools may expose students to religion. The harder question is whether this particular field trip crossed the line between teaching about Islam and facilitating religious exercise.
The Establishment Clause of the First Amendment prevents the government from establishing or promoting religion. In School District of Abington Township v. Schempp (1963), the Supreme Court struck down school-sponsored Bible reading and prayer but made clear that schools may objectively teach about religion as part of an academic program. For that reason, I do not think the mosque visit itself violated the Establishment Clause. Watching prayer can help students understand how a religion is practiced, and a Quran can be studied academically just as a Bible or Torah can.
The allegation that the program presented Islam more favorably than other religions raises a separate concern. In Larson v. Valente (1982), the Supreme Court made clear that the government cannot favor one religious denomination over others. Spending more time learning about Islam would not by itself prove unconstitutional favoritism. However, if the evidence shows that the school promoted Islam while treating other religions differently, that could create an additional Establishment Clause problem.
The constitutional concern becomes more serious when considering whether students were encouraged to participate. If students were simply shown a hijab and taught why some Muslim women wear one, that seems educational. If school officials or hosts encouraged students to put one on as part of experiencing the faith, however, I think that goes further. There is an important difference between studying a religious practice and asking a student to take part in one.
The Supreme Court's recent Establishment Clause decisions complicate this question. In Kennedy v. Bremerton School District (2022), the Court rejected older approaches such as the Lemon test, which focused partly on whether government action had a secular purpose or promoted religion, and instead emphasized historical practices and understandings.
Still, Kennedy did not erase the Court's concern about coercing students. It cited Lee v. Weisman (1992), which held that a public school could not involve students in government-sponsored prayer at graduation. Lee recognized that students can face social pressure even when no one directly orders them to participate. In Kennedy, by contrast, the Court found no comparable coercion when a football coach engaged in personal prayer without requiring students to join him. A school-sponsored field trip is different. Students participating in an academic program may feel less free to simply walk away from an activity. Even so, general pressure may not be enough. There would need to be evidence that the school actually encouraged religious participation.
The parents may also have a Free Exercise argument, although I think it is weaker than their Establishment Clause claim. Their potential burden is not simply that their children learned about Islam. Instead, they could argue that their children were placed in activities conflicting with their families' religious beliefs without sufficient notice or an opportunity to opt out. In Mahmoud v. Taylor (2025), the Supreme Court ruled that parents were entitled to notice and an opportunity to opt their children out of particular public-school instruction that substantially burdened their religious exercise. The facts are different here, but Mahmoud suggests that parental notice can become important when school activities seriously conflict with a family's religious exercise.
Based on what is publicly known so far, I think the school has the stronger argument if students simply visited the mosque, observed prayer, and learned about Islam. The outcome should be different if the evidence shows that school officials encouraged students to participate in religious practices or intentionally favored Islam over other faiths.
This case shows why schools do not have to choose between ignoring religion and promoting it. They can expose students to religious traditions while maintaining a clear boundary. Students may be asked to learn, but they should not be asked to practice. Giving parents clear notice of religious site visits and an opportunity to opt out would make that boundary even stronger.



forces them to participate in a process that directly violates their Islamic beliefs. It raises the constitutional question: Can the government require doctors to participate in a legal medical process if it conflicts with their religious beliefs? The Illinois’ law, which took effect on September 12, permits terminally ill adults to access medication that they can take to end their lives. In order to qualify, a patient must be an Illinois resident, be at least 18 years old, have the mental capacity to make medical decisions, and have a terminal illness expected to result in death within six months. The medication must also be self-administered by the patient.
