* Specific school policies: Each high school will have its own student handbook or code of conduct that outlines expectations for cheerleaders. Some schools might be very strict, allowing uniforms only during official school events. Others might be more lenient.
* Coach's discretion: The cheerleading coach often has significant authority in determining when and where uniforms can be worn. They might have rules about appropriate occasions (games, competitions, practices) and situations (public appearances, school events).
* Uniform condition: Schools may require uniforms to be clean and in good repair when worn outside of practice.
* Context and appropriateness: Even with less strict rules, common sense dictates that uniforms should be worn appropriately. Wearing a uniform to a party, for instance, might be considered inappropriate by the school.
To know the specific rules for a particular high school, you should check the school's student handbook, contact the cheerleading coach, or ask school administration.
