Teachers in public schools have limited freedoms in the classroom to teach without undue restrictions on the content or subjects for discussion. These freedoms are based on rights to freedom of expression under the First Amendment of the Bill of Rights. However, the concept of academic freedom is quite limited. The content taught by a teacher must be relevant to and consistent with the teacher’s responsibilities, and a teacher cannot promote a personal or political agenda in the classroom. Factors such as the age, experience, and grade level of students affect the latitude in which a court will recognize the academic freedom of a teacher.
