Girl In School Uniform Outfit

In England and Wales, technically a state school may not permanently exclude students for "breaching school uniform policy", under a policy promulgated by the Department for Children, Schools and Families but students not wearing the correct uniform are asked to go home and change.
In Scotland, some local councils (that have responsibility for delivering state education) do not insist on students wearing a uniform as a precondition to attending and taking part in curricular activities.
Turkey abolished mandatory uniforms in 2010.
In the United States, a few states have regulations declaring that public schools must allow students to drop out of uniform policies. Although Section 83 of the Massachusetts Legislature appears to prohibit dress codes in public schools by declaring that schools may not "abridge the rights of students as to personal dress and appearance", Section 86 states that "The provisions of sections eighty-three to eighty-five, inclusive, shall apply only to cities and towns which accept the same" and other sections of the law allow schools to impose dress codes, and in fact many public schools in Massachusetts (mostly in the Boston area) have mandatory school uniforms.
