School uniforms should be a part of school systems, because statistics have shown that students who wear uniforms are better off than dress codes. Additionally, more students feel a sense of equality among themselves and there is less judgment of others. It allows the teacher to quickly identify people who don't belong in the building and limit the ways gangs can identify themselves. School clothing provides identity, individual spirit and pride to students. Uniforms are increasing in several schools. School uniforms make students more formal and progressively affect students' self-esteem, discipline and confidence, and develop students more confident in what they can achieve in life. First, uniforms are easier for the school to enforce than non-uniforms. UniformsWhen students are not wearing uniform, they tend to behave as they are dressed at school. Uniforms should help students concentrate and do better in school and outside of school. School attire is one of several demand factors that influence learning. It allows students to appear more formal on their personality and not on the way they dress. Students are allowed to determine what is expected in school and the freedom they have outside of school in fashion. It also helps students be more disciplined in their education and avoid distractions such as dress-designing competitions with each other. Statistics from the National Association of Elementary School Principals (NAESP) and the Asia-Pacific Economics Blog (APECSEC) showed that uniforms had an 85% impact on classroom discipline and a 44% impact on attendance (School Uniforms Pros and Cons 5) and (National Association of Elementary School Principals) School Principle 1-2). When the school system does not require students to wear uniforms and represent the school, sometimes students are not willing to attend classes. Professor Scott
