Meetings that begin with a prayer include funerals and other religious gatherings, such as Sunday school classes. Some other organizations, such as faith-based charities or businesses, may begin meetings with a prayer.
Beginning meetings with prayer is common in private religious schools, but public schools cannot require students to pray, in accordance with the Establishment Clause of the First Amendment to the U.S. Constitution.
Local government meetings sometimes begin with a prayer, depending on the jurisdiction. In 2014 the U.S. Supreme Court ruled that opening local government meetings with prayer doesn't violate the law, as long as the prayer does not promote or disparage any particular religion, and leaders do not coerce people to participate.
