Public school students have been using the Internet to tease, bully, and ridicule their classmates, teachers, and schools. The Supreme Court has held that schools can punish students for some speech without violating the constitution, if it is uttered on school grounds during school hours. Courts, however, have been divided over when, if ever, schools may punish students for comparable off-campus cyberspeech. Because the Supreme Court has provided no direct guidance, this Note examines the Supreme Court's view of students' First Amendment rights on campus, the student-teacher relationship, and basic First Amendment principles to determine whether schools may punish students fir off-campus cyberspeech that would otherwise be protected by the First Amendment. This Note concludes that although, in some circumstances, schools may punish students for off-cainpus cyberspeech that attacks their fellow students, it is unconstitutional for schools to do the same where the student speech targets teachers, administrators, or the school itself.
