Days after Acero charter schools leaders voted to close seven schools, Chicago Teachers Union President Stacy Davis Gates wrote a letter demanding that Chicago Public Schools absorb them into the district in order to save them.The closures — which will begin in June 2025 and impact about 2,000 students, or nearly a third of all Acero students — include Casas, Cisneros, Fuentes, Paz, Santiago and Tamayo elementary schools and Cruz K-12. The network of schools operates primarily in Latino neighborhoods.In the letter delivered to CPS leadership Friday, Gates cited a resolution barring the closure of any district-managed schools through the 2026-27 school year, and said CPS must apply that rationale with charter schools by transitioning the closing schools to being district-run “with seats guaranteed for all current students and jobs guaranteed for all current staff members.”“The incompetence, unaccountability, and mismanagement of charter school operators should have consequences,” Gates wrote in the letter. “Noncompliant charter organizations should be held accountable. What is needed is to replace the management of these schools, not to leave their students and staff members in the lurch.” Related Acero plans to close 7 charter schools, blindsiding parents, teachers — ‘They did not inform us’ Chicago closed 50 public schools 10 years ago.
