The general atmosphere of a school must be conducive to learning. Generally, attire at school should be considered “learning outfits” which are different from those that might be considered more suitable for evening wear or an exercise class. A student's clothing or general appearance which materially or substantially interferes or disrupts the educational environment or invades the rights of others is prohibited. Additionally, a student's clothing or appearance which is vulgar, indecent, obscene or insulting, or which promotes or encourages behavior such as smoking, drinking, drug use, physical or sexual violence or the use of illegal substances, or which promotes illegal activities is prohibited. Outdoor clothing such as headgear, sunglasses, gloves, coats, etc., is to be removed upon entering the building and stored in lockers or other school designated areas.
