Oakland Unified School District’s Excel and Mandela high schools have found the right formula to keep students engaged and invested in educations – and they are sharing it with the public. With a focus on public service, Excel High School’s senior class recently stood before the student community and the public and discussed, presented the facts and defended their dissertations on varied topics. Some of these included teen pregnancy, homelessness, the affects of drugs and alcohol on families, single-parent households, literacy and even police violence.
