As a high school junior, Caleigh Wood refused to complete a history lesson on “The Muslim World” that she said forced her to embrace Islam in conflict with her Christian faith — and the Constitution.

A federal appeals court this week disagreed, saying school officials in Southern Maryland had not violated Wood’s First Amendment rights because the curriculum did not endorse a particular religion “and did not compel Wood to profess any belief.”

“School authorities, not the courts, are charged with the responsibility of deciding what speech is appropriate in the classroom,” wrote Judge Barbara Milano Keenan, who was joined by Judges Pamela Harris and James A. Wynn Jr. “Academic freedom would not long survive in an environment in which courts micromanage school curricula and parse singular statements made by teachers.”

Attorney Andrew Scott, who represents Charles County school officials, said Tuesday the ruling sends an important message to school officials throughout the state affirming their discretion to teach about religion.
