Interestingly, even when evidence is available, educators’ perceptions could be at odds with it. For example, a study of educators in 38 North Carolina high schools found that 61% of the responding principals and assistant principals believed that there was a reduction in cases of misbehavior on campus when school uniforms were introduced. In reality, the data showed no change in incidents of crime, violence and suspensions.
Similarly, research on the efficacy of school uniforms on increasing student attendance and achievement is conflicted. For example, one study concluded that school uniforms resulted in increased student achievement and increased attendance.
However, another study found little impact on academics at all levels and little evidence of improvement in attendance for girls and drop in attendance for boys.
