Yes, if, and only if, the moment of silence is genuinely neutral. A neutral moment of silence that does not encourage prayer over any other quiet, contemplative activity will not be struck down, even though some students may choose to use the time for prayer. (See Bown v. Gwinnett County School Dist., 11th Cir. 1997)

If a moment of silence is used to promote prayer, it will be struck down by the courts. In Wallace v. Jaffree (1985) the Supreme Court struck down an Alabama “moment of silence” law because it was enacted for the express purpose of promoting prayer in public schools. At the same time, however, the Court indicated that a moment of silence would be constitutional if it is genuinely neutral. Many states and local school districts currently have moment-of-silence policies in place.
