School uniform is the clothing pupils are required to wear at school. Uniforms vary from the very formal (requiring blazers) to more informal (involving just a school sweatshirt). Schools have uniforms in different styles and colours to identify pupils as attending a particular institution. Uniforms are required in most schools in the UK.

Puntuación de la evidencia

There are no systematic reviews or meta-analyses of well-controlled interventions of a school uniform policy. The evidence rests mainly on correlational studies that have compared the performance of schools with uniforms to those without, or that have examined a school's trajectory of improvement after the introduction of school uniform. The most rigorous reviews and analyses have so far been unable to establish a causal link, but speculate that adoption of a uniform policy may provide a symbolic and public commitment to school improvement. Overall, the evidence is rated as very limited.

Información coste adicional

The costs associated with introducing a school uniform are very low and mainly depend on parents buying the uniform instead of other clothing the child would wear.
