In the United States, certain religious schools are legally permitted to limit or discontinue student enrollment if:
the atmosphere or conduct within a particular home, the activities of a parent or guardian, or the activities of the student are counter to, or are in opposition to, the biblical lifestyle the school teaches. This includes, but is not limited to contumacious behavior, divisive conduct, and participating in, supporting, or condoning sexual immorality, homosexual activity or bi-sexual activity, promoting such practices, or being unable to support the moral principles of the school. (Lev. 20:13 and Romans 1:27.)
