　　Many high schools, both public and private, require students to wear uniforms. I think that such a policy is an excellent idea because uniforms can make things more equal for all students.
　　First, uniforms make students equal on an economic level. With uniforms, students from poor families dress the same as students from rich families. This can prevent envy and jealousy about stylish clothes. It can also encourage students to form friendships based on personality, not clothes.
　　Second, uniforms can reduce unequal treatment by teachers. Research suggests that teachers often have higher expectations for more attractive students, which include those students with nicer clothes. This special attention can include providing more challenges and opportunities for these students. Uniforms help teachers make judgments based on ability, not appearance.
　　Finally, uniforms encourage the individual students of a school to feel like part of a bigger group. Their feelings of being together, working together and having something in common are all helped by uniforms.
　　It is my opinion that all schools should have a policy requiring uniforms. Uniforms give every student an equal chance.
