Community standards are local norms bounding acceptable conduct. Sometimes these standards can be itemized in a list that states the community's values and sets guidelines for participation in the community. Alternatively, informal standards may be imprecisely described as "I'll know it when I see it."
Often, such standards are invoked in legal situations to resolve disputes, especially around pornography. Critics argue that puritanical moralists have used community standards to wrongly punish minorities such as homosexuals or those in interracial marriages.
Colleges and universities enforce their standards through conduct offices in their Student Affairs divisions.
