Educational reformers often partner with others to make change happen in their schools. But few reformers look to students as agents of change. In this article, the authors discuss how students are an often under-utilized, and yet crucial, educational partner. They share their student voice work in the San Diego Unified School District's high school reform initiative. They specifically discuss what they call the student co-researcher project (SCR) to show how high school students can become active partners in educational reform. Also discussed is the potential impact SCR projects can have on schools by informing educators about students' perspectives and by creating opportunities for teachers and students to discuss problems and solutions.
