Cultural references related to rules, expectations, and related controversies at American high schools have come up when I'm working with advanced English Language Learners (ELLs) who are also teacher candidates: Example terms are curfew, eligibility, and dress code.
To give you an idea of the vocabulary and references that you might come across, I'm posting sections of a 2011 student welcome packet. "Eligibility" refers to meeting a minimum academic standard, as measured by letter grades in classes, which allows a student to be eligible to participate in sports competitions with other schools. Instead of school uniforms, most public schools have a "dress code" to promote a respectful learning environment. "Curfew for minors," which is the time that those under 18 years old have to be home so that their parents are not called into court, is not covered here.
