Vernonia Sch. Dist. 47J v. Acton (94-590), 515 U.S. 646 (1995).

(b) The first factor to be considered in determining reasonableness is the nature of the privacy interest on which the search intrudes. Here, the subjects of the Policy are children who have been committed to the temporary custody of the State as schoolmaster; in Page II that capacity, the State may exercise a degree of supervision and control greater than it could exercise over free adults. The requirements that public school children submit to physical examinations and be vaccinated indicate that they have a lesser privacy expectation with regard to medical examinations and procedures than the general population. Student athletes have even less of a legitimate privacy expectation, for an element of communal undress is inherent in athletic participation, and athletes are subject to preseason physical exams and rules regulating their conduct. Pp. 7-11.
