Some educational jurisdictions in the United States require students to perform community service hours to graduate from high school. In some high schools in Washington, for example, students must finish 200 hours of community service to get a diploma. Some school districts in Washington, including Seattle Public Schools, differentiate between community service and "service learning," requiring students to demonstrate that their work has contributed to their education. If a student in high school is taking an AVID course, community service is often needed. Whether American public schools could require volunteer hours for high school graduation was challenged in Immediato v. Rye Neck School District, but the court found no violation.
