Summary

Keller ISD staff told the SHAC the district plans to replace a 2005 'real‑feel' temperature rule with a wet‑bulb metric used by UIL athletics; the change would rely on campus weather stations and an app and seeks SHAC feedback on behavior‑related limits and parent notification.

Keller ISD presented a proposed update to its recess administrative regulation that would replace use of a ‘real‑feel’ or ambient temperature with a wet‑bulb temperature metric to determine whether students have outdoor recess.

Jennifer Price, speaking to the School Health Advisory Council, said the wet‑bulb metric — which factors in temperature, humidity, wind, sun angle and cloud cover — is already used by the district’s athletic and fine‑arts programs. She said the district plans to rely on weather stations at its four high schools and an app that provides local wet‑bulb readings to campus staff.

“[The wet‑bulb metric] is an indicator of heat‑related stress on the human body at work or play in direct sunlight,” Price said, explaining why the district is considering the change.

The district reviewed its 2005 administrative regulation, which currently allowed students to miss up to 50% of a 30‑minute recess period for behavior or missing work. Price asked SHAC members to advise whether the revised regulation should include behavior provisions — for example, a maximum time limit (she mentioned a five‑minute figure as a question) or a cap on how many times per month a student may miss recess before escalation to administrators — and whether parental notification should be required when students miss recess.

Summer Crowe said a short feedback form will be distributed to SHAC members the next day, with a requested return by Friday so the district can begin drafting the updated regulation.

The SHAC did not take formal action; Price’s presentation was positioned as an information request to solicit committee input ahead of drafting the revised administrative regulation.
