As an instructional leadership director in the Tulsa, Okla., school district, Julio César Contreras is redefining what it means to supervise principals. He eschews micromanaging school leaders and instead works alongside them to help them meet the goals of the district’s long-range plan and to improve teacher performance in their schools. He holds frequent meetings with principals to discuss and improve their work, visits classrooms constantly, and strategically uses data about classroom performance to help school leaders make decisions. In this webinar, Contreras, a 2016 Education Week Leaders To Learn From honoree, will detail the strategies he uses to partner with principals to help them grow professionally, as well as support their work to improve teaching and learning in their schools.
