Are public school choruses allowed to perform in a church?
There are no First Amendment barriers to prevent a public school chorus from performing in a house of worship during non-worship times. The 10th U.S. Circuit Court of Appeals addressed this issue in its 1997 opinion Bauchman v. West High School and rejected the notion that merely singing in a religious venue would support an establishment-clause claim. The situation would likely be different if a performance coincided with an actual worship service, as that could be construed as the school’s endorsing or supporting the church or that religion.
