Public schools; industry-recognized uniform inspection and evaluation of indoor air quality.

Replaced a broad list of 14 inspection items with a revised list of 13 items that focus on specific, measurable hazards such as radon, carbon monoxide, and fine particulate matter, while removing general tests for pesticides and broad pest infestations.

Added a specific requirement to test for fine particulate matter (PM2.5 and PM10) and to report observable signs of pests rather than testing for their presence.

Updated the radon testing requirement to explicitly reference existing state law (§ 22.1-138) and Department of Health guidance.

Modified the mold testing requirement to be conditional, requiring testing only when observable mold growth or water incursion is detected, rather than as a blanket requirement.

Established a new effective date of July 1, 2027, for the provisions of the act.
