Students in the public schools do not "shed their constitutional rights to freedom of speech or expression at the schoolhouse gate." Tinker, supra, at 506. They cannot be punished merely for expressing their personal views on the school premises - whether "in the cafeteria, or on the playing field, or on the campus during the authorized hours," 393 U.S., at 512 -513 - unless school authorities have reason to believe that such expression will "substantially interfere with the work of the school or impinge upon the rights of other students." Id., at 509.
We have nonetheless recognized that the First Amendment rights of students in the public schools "are not automatically coextensive with the rights of adults in other settings," Bethel School District No. 403 v. Fraser, 478 U.S. 675, 682 (1986), and must be "applied in light of the special characteristics of the school environment." Tinker, supra, at 506; cf. New Jersey v. T. L. O., 469 U.S. 325, 341 -343 (1985). A school need not tolerate student speech that is inconsistent with its "basic educational mission," Fraser, supra, at 685, even though the government could not censor similar speech outside the school. Accordingly, we held in Fraser that a student could be disciplined for having delivered a speech that was "sexually explicit" but not legally obscene at an official school assembly, because the school was entitled to "disassociate itself" from the speech in a manner [484 U.S. 260, 267] that would demonstrate to others that such vulgarity is "wholly inconsistent with the `fundamental values' of public school education." 478 U.S., at 685 -686. We thus recognized that "[t]he determination of what manner of speech in the classroom or in school assembly is inappropriate properly rests with the school board," id., at 683, rather than with the federal courts. It is in this context that respondents' First Amendment claims must be considered.

The public schools do not possesses all of the attributes of streets, parks, and other traditional public forums that "time out of mind, have been used for purposes of assembly, communicating thoughts between citizens, and discussing public questions." Hague v. CIO, 307 U.S. 496, 515 (1939). Cf. Widmar v. Vincent, 454 U.S. 263, 267 -268, n. 5 (1981). Hence, school facilities may be deemed to be public forums only if school authorities have "by policy or by practice" opened those facilities "for indiscriminate use by the general public," Perry Education Assn. v. Perry Local Educators' Assn., 460 U.S. 37, 47 (1983), or by some segment of the public, such as student organizations. Id., at 46, n. 7 (citing Widmar v. Vincent).
If the facilities have instead been reserved for other intended purposes, "communicative or otherwise," then no public forum has been created, and school officials may impose reasonable restrictions on the speech of students, teachers, and other members of the school community. 460 U.S., at 46 , n. 7. "The government does not create a public forum by inaction or by permitting limited discourse, but only by intentionally opening a nontraditional forum for public discourse." Cornelius v. NAACP Legal Defense & Educational Fund, Inc., 473 U.S. 788, 802 (1985). [484 U.S. 260, 268]
