No they shouldn't. Uniforms should only be mandatory in private schools. Public schools should never require a student to wear uniforms. This takes away from a student's freedom of expression.Freedom of expression is very important at that age.hey promote a businesslike setting. Yes, I believe that uniforms should be mandatory. Uniforms makes for a team atmosphere. Uniforms also move students minds from judging what each other is wearing to focusing on learning. School has become more of a fashion show then a place for learning.
