Freedom of association is a fundamental right guaranteed by the first amendment. This encompasses the right of individuals to voluntarily join and leave groups, as well as the right of individuals to form groups to pursue common interests. This right makes it possible for people with diverse opinions to live peacefully in pluralistic communities and to come together with others who share their values, practices, culture, and beliefs. It protects students' rights to hold beliefs that may diverge from the school or the majority of students. It also means that people are free to associate and organize with others for a common cause. Protecting freedom of association on campuses ensures that students and student organizations can thrive. In this document, the James G. Martin Center for Academic Renewal (Martin Center) recommends steps that legislatures, university boards, and faculty governing committees can take to protect freedom of association on campus. Model university policies, recommendations for policymakers, and links to model legislation and further reading are also included.
