National Honor Society (NHS) chapters typically have rules against underage drinking, and often against any alcohol use, regardless of age. While the specific wording varies from chapter to chapter and school to school, the underlying principle is consistent: NHS membership requires upholding high standards of character, and alcohol consumption, especially underage, is generally considered inconsistent with those standards.
Consequences for violating these rules can range from warnings and probation to suspension or expulsion from the NHS. The specific consequences depend on the chapter's rules, the school's policies, and the severity of the infraction. It's important to check your specific chapter's bylaws and school's code of conduct for precise details.
