The Establishment Clause of the First Amendment prohibits government from promoting religion. Prayers in school or at a school activity violate this clause. Schools are prohibited from discriminating against pregnant or married students. A school may offer special classes for pregnant students. The student is not required to attend these classes if she would prefer to be in her regular classes.
Students have fewer privacy rights in school than out of school.
Metal detectors are allowed in many states. Courts have ruled that a metal detector is less of an invasion of privacy than other kinds of searches. Metal detectors cannot be used selectively, i.e., on a certain group of students and not others. Tracking systems are all right if the students are separated on the basis of learning ability and not on a racial, ethnic, or gender basis. Moreover, any tracking system used by a school system must ensure that all students are given the same basic education.
