At Arlington Heights High School, a grassroots effort began in the 2010-2011 school year with the formation of a new committee of teacher leaders on campus, tasked with envisioning and creating campus change hand-in-hand with administration. This committee's membership has continued to evolve over the last five years, and we are now known as the School Innovation Design Team as our work expands to include the "National Center for Scaling Up Effective Schools Student Ownership and Responsibility" innovation. There are several reasons why we have been able to create change on a campus-wide level. First, campus administration allowed the team the flexibility to develop, change and throw out school-wide practices. Second, we used faculty feedback and discussions, along with passing rates (both state testing and credit/no credit) to guide the direction of the changes. Third, the district recognized our successes and continued to give us the support necessary to continue to make changes. We have begun to see results, making it easier to convince doubters that we actually can change our direction, our focus and our outcomes. The development of a leadership team, made up of teachers and responding to teacher-driven issues and questions, is an integral part of our success in building not only student ownership on our campus, but teacher ownership as well. We believe the model of teacher leadership and ownership is one that can be replicated on other campuses in our district and beyond.
