Final answer:
A recent study concluded that school uniforms improve graduation and attendance rates, providing the best evidence for supporting mandatory school uniforms.
Step-by-step explanation:
The best evidence for a claim supporting mandatory school uniforms is a recent study that concluded school uniforms improve graduation and attendance rates.
- Graduation rates: Mandatory school uniforms can improve graduation rates by fostering a sense of belonging and reducing distractions related to clothing choices. This can lead to increased focus and engagement in the classroom, ultimately resulting in higher graduation rates.
- Attendance rates: School uniforms can also improve attendance rates as they eliminate peer pressure and bullying related to clothing, reducing the potential barriers that may discourage students from attending school.
Therefore, the study showing the positive impact of school uniforms on graduation and attendance rates is the best evidence supporting the claim for mandatory school uniforms.
