Courses in the arts develop skills specific to the discipline. Research also suggests that the arts contribute to enhanced attentiveness, engagement in school, communication skills, and critical and divergent thinking. Other studies point out benefits for at-risk students in reducing negative outcomes such as dropout and crime rates. Studies report a correlational relationship between arts education and reading achievement, but a causal link has not been established. Thus, there is evidence of benefits of the arts that can support students' success in school, but more high quality causal studies are needed.
