Ultimately, however, it is the result of a concerted effort over more than a decade by organized and committed activists, local and national, who have opposed changing the governance and operation of school districts in any significant way. The politics of public education in Denver have grown increasingly in school systems across the country. What distinguishes the conflict over reform in Denver is how unrelated it is to student outcomes. While Denver's reforms have been far from perfect, they merit the national attention they've drawn. A growing body of evidence makes clear that outcomes for students in the city slowly yet significantly improved, including for students the district has historically failed to serve well. Yet as soon as Denver Public Schools took its initial steps toward reform less than two decades ago, an active opposition campaign arose, aimed not at moderating or improving the reforms, but at destroying them. In 2019, the election of three new anti-reform members to the Denver Board of Education flipped the board majority to that camp. Since the educational reform was launched in 2005, Denver's families and educators have embraced choice. The broad popularity of choice in Denver makes dismantling reform politically fraught for the board and its allies. In fact, the board has faced strong pushback from some parents and educators and has had to confront the complex reality of governing a district where choice, autonomy, and a focus on outcomes are now woven into the fabric of public education. But the union-supported board majority was determined to push ahead, and that meant cleaninghouse at the top. In fall 2020, Superintendent Susana Cordova resigned after less than two years on the job. Cordova is a Denver native and Denver Public Schools graduate who had spent most of her professional career working for the district. Cordova never got a chance to enact her own agenda. First, a teacher strike weakened her just weeks into her tenure. Next, the new board gave her no room to enact changes. Finally, softening the impacts of the Covid-19 pandemic became the district's sole focus. Now that the pandemic's disruption is receding, the board appears poised to renew its efforts to roll back reform. It has a good chance of succeeding, because in November 2021, all four of the anti-reform candidates won, giving their side unanimous control.
