J. L. Mann students are expected to dress and be groomed in such a way as to not distract or cause disruption in the educational program or orderly operation of the school. Personal appearance of students should promote health and safety, contribute to a climate conducive to teaching and learning and project a positive image of the school to the community. The administration may make additions or changes to these standards.

Students who do not meet the dress code will not be allowed to go to class. If any apparel is considered indecent or in any way unacceptable by the staff or administration, the student may be required to go home and change or remain in the In-School Suspension Room. Students who are addressed multiple times could face additional disciplinary action.
