EPA's IAQ Tools for Schools program is the canonical U.S. framework for managing indoor air quality in K-12 environments. The program has been in continuous development since 1995 and is structured around six elements: organize an IAQ team, communicate the program, assess the building, plan interventions, act on findings, and evaluate effectiveness.
The materials are practical. The Action Kit includes printable checklists for teachers (classroom-level walkthroughs), facilities staff (HVAC and building-envelope), and administrators (program management). The Framework for Effective School IAQ Management documents how districts that adopted the program reduced asthma-related absences, lowered remediation costs, and improved standardized test scores.
For districts new to IAQ management, EPA recommends starting with the building walkthrough: visual inspection for water damage, verification that HVAC filters are current, checks that unit ventilators are operating, inspection of cleaning-product storage, and a survey of occupant complaints. The walkthrough usually identifies the biggest problems within a single school day; sensor data extends it to the slow-burn issues a walkthrough misses.
Continuous monitoring (CO2, PM2.5, VOC, T, RH) is now mentioned in the latest framework updates as a complement to checklist-based audits, particularly for verifying remediation effectiveness and for documenting before/after states during HVAC retrofits. CDC NIOSH publishes complementary HVAC filtration guidance.
