prayers for civic occasions: Through these means, the principal directed and controlled the content of the prayers. Even if the only sanction for ignoring the instructions were that the rabbi would not be invited back, we think no religious representative who valued his or her continued reputation and effectiveness in the community would incur the State's displeasure in this regard. It is a cornerstone principle of our Establishment Clause jurisprudence that it is no part of the business of government to compose official prayers for any group of the American people to recite as a part of a religious program carried on by government, and that is what the school officials attempted to do. Kennedy also noted that the nonsectarian nature of the prayer was no defense, as the Establishment Clause forbade coerced prayers in public schools, not just those representing a specific religious tradition.

Everyone knows that, in our society and in our culture, high school graduation is one of life's most significant occasions. A school rule which excuses attendance is beside the point. Attendance may not be required by official decree, yet it is apparent that a student is not free to absent herself from the graduation exercise in any real sense of the term "voluntary," for absence would require forfeiture of those intangible benefits which have motivated the student through youth and all her high school years.

And the State may not place the student dissenter in the dilemma of participating or protesting. Since adolescents are often susceptible to
