The IAQ Evaluation is an assessment mandated by the State of Connecticut to ensure that public schools have proper ventilation and effective air filtration systems, meeting the indoor air quality (IAQ) verification requirements of the state legislation Public Act No. 23-167. It does not directly measure air quality but focuses on evaluating the delivery and filtration of ventilation air in K-12 facilities.

All public schools in Connecticut are required to undergo an IAQ evaluation, in response to State legislation mandating IAQ verification and providing standards for compliance.
The IAQ verification requirement was first established by legislation passed in 2022. The mandate was revised in 2023 to provide clearer guidelines on compliance and to assist municipalities in implementing the evaluations.
The IAQ evaluations are conducted on-site at each school to ensure compliance with state regulations.
IAQ evaluations must be conducted by certified professionals, such as testing, adjusting, and balancing technicians.

A new bill has been introduced to the Connecticut Senate regarding indoor air quality in schools. It proposes extending the deadline for reporting indoor air quality in school buildings, allowing the cost of inspections and evaluations to be reimbursed under the HVAC system grant program and granting school boards flexibility in the way they are conducted. The bill mandates that local or regional boards of education inspect and evaluate their HVAC systems in school buildings, with at least 20% of schools inspected each year from July 1, 2025, to June 30, 2030, and every five years thereafter.

Details are still emerging, but current legislation requires the creation of standard reporting forms to be made available online.

The IAQ Evaluation is critical for the following reasons:

  • Health and Safety: Ensuring that students and staff are breathing clean, well-filtered air, which can reduce the spread of airborne illnesses and improve overall health.
  • Educational Environment: Promoting a healthier, more productive learning environment by maintaining optimal indoor air quality.
  • Regulatory Compliance: Helping schools meet state mandates and avoid potential penalties.
Every public school in Connecticut is required to undergo the IAQ evaluation every five years. This regular assessment helps ensure ongoing compliance with state standards and maintains the quality of indoor air over time.
