Opinion of the Court
sion as to the Policy's constitutionality. 242 F. 3d 1264, 1270 (2001). Before imposing a suspicionless drug testing program, the Court of Appeals concluded that a school "must demonstrate that there is some identifiable drug abuse problem among a sufficient number of those subject to the testing, such that testing that group of students will actually redress its drug problem." Id., at 1278. The Court of Appeals then held that because the School District failed to demonstrate such a problem existed among Tecumseh students participating in competitive extracurricular activities, the Policy was unconstitutional. We granted certiorari, 534 U. S. 1015 (2001), and now reverse.

We must therefore review the School District's Policy for "reasonableness," which is the touchstone of the constitutionality of a governmental search.
In the criminal context, reasonableness usually requires a showing of probable cause. See, e. g., Skinner v. Railway Labor Executives' Assn., 489 U. S. 602, 619 (1989). The probable-cause standard, however, "is peculiarly related to criminal investigations" and may be unsuited to determining the reasonableness of administrative searches where the "Government seeks to prevent the development of hazardous conditions." Treasury Employees v. Von Raab, 489 U. S. 656, 667-668 (1989) (internal quotation marks and citations omitted) (collecting cases). The Court has also held that a warrant and finding of probable cause are unnecessary in the public school context because such requirements " 'would unduly interfere with the maintenance of the swift and infor-
