Scientists and advocates asked the Joint Committee on Education to require indoor air‑quality monitors in K‑12 classrooms so districts can detect ventilation failures, protect students during heat or smoke events, and prioritize infrastructure investments.

Researchers from Boston University and the World Health Network explained that classroom conditions vary widely within the same building and that data from continuous monitors can inform short‑term responses (open windows, portable filters) and long‑term capital planning. “Real time air quality data can both empower timely adjustments during acute events … and inform maintenance and long term investments,” a study lead said.

Why it matters: Testimony linked poor ventilation and high CO2 levels to reduced concentration and higher absenteeism; speakers noted older buildings without mechanical ventilation may be especially vulnerable during heat waves and wildfire smoke events.

Policy recommendations: Witnesses asked the committee to adopt House Bill 583 requiring monitors and Senate Bill 351 to create a task force to develop standards and an equitable implementation timeline. They urged a phased approach — a 180‑day planning phase for DESE followed by staged installation — and transparent public reporting of classroom data.

Next steps: The committee heard the bills; speakers recommended revised, achievable deadlines and pledged technical support; advocates urged funding pathways to equip older, underfunded districts first.
