The Denver Public Schools superintendent Michael Bennet has vowed to reverse the district's tide of declining enrollment, improve test scores and get more kids to graduate. He's pushing a package of reforms, including a controversial redesign of North High School. There, teachers will have to reapply for their jobs or leave the school, and Bennet says students will face greater rigor in the classroom. The superintendent talks to Ryan Warner about his plans for restructuring North and about districtwide reforms.
