Chapter 11 of a book on school law highlights the legal context of extracurricular activities in relationship to sex discrimination. First, the legal issues raised by Title IX of the Education Amendments of 1972 are examined. In general, this statute, with limited exceptions, requires that extracurricular activities be open to students without regard to gender. Second, the right versus privilege controversy is explored. Here, the issue is not whether the students have an absolute right to participate in extracurricular activities but whether students, based on their gender, can be denied the benefits of activities provided by the state. Third, the issues concerning sex-based classification and discrimination are explored. Although sex-based classifications do not come to court with the same presumption as do those of race or national origin, courts have had little trouble in finding sex-based classifications in education that violate the Equal Protection Clause of the Fourteenth Amendment. Finally, the possible consequences of discriminatory actions are raised. (Author/MLF)
