Chicago Public Schools (CPS) preserves its Gold Certification from the Healthy Green Schools & Colleges (HGSC) program for meeting rigorous national standards that promote healthier school indoor environments, cost-effective facility operations, and environmental responsibility. The Gold Certification reinforces the District’s commitment to providing clean, safe, and environmentally-sound learning spaces for its more than 315,000 students and 46,000 staff members across 522 campuses and 793 buildings. Toward the end of the 2025 school year, the District achieved Gold Certification from the HGSC, making history as the first K-12 school district in the nation to reach this milestone in sustainable education facility management. With this certification, the District receives recognition on the HGSC website and prominently uses the HGSC certification mark. As part of the Gold Certification, the HGSC mandates that CPS implement strategic measures regarding operations, staff training, indoor air quality management, procurement, HVAC and electrical system maintenance, water quality monitoring, and pest management.
