Two programs can take the exact same WBGT readings and end up in very different places. The one that wrote the readings down, kept them on file, and built an emergency action plan around them can show it did the right thing. The one that read a meter and moved on cannot. The difference is documentation, and it is the part of the rule that gets the least attention.
The UIL directs schools to record the WBGT readings taken for outdoor practices and keep them on file. A defensible record for each reading captures:
The heat requirement is not only about slowing practice down. Each school's emergency action plan must include procedures for heat emergencies that provide onsite rapid cooling using cold-water immersion or an equivalent means. Alongside that, the rule calls for unrestricted access to water at all times and rest breaks with unlimited hydration. A student should never be denied water, and energy drinks are not a substitute.
Taking a reading is a moment. Keeping a clean, complete, retrievable file of every reading across an entire season, at every site, is a system. When it depends on someone writing numbers on a clipboard during a hectic practice, readings get skipped, sheets get lost, and the file has gaps exactly where you would least want them. If anyone ever asks to see the records, the gaps are the problem, not the readings you did take.
Weatherstem already operates stations across Texas, including at the University of Texas, Texas A&M, and Texas Motor Speedway, and more than 900 nationwide. The station records WBGT continuously with timestamps, so the file builds itself instead of depending on a clipboard, it exports a clean record for any site and date range on demand, and its zone-transition alerts prompt the cooling response on time, which is what the emergency action plan is there to ensure.
Schools should record the WBGT readings taken for outdoor practices and keep them on file. Readings are taken within 15 minutes before the start and every 30 minutes during, ideally by the same person.
Procedures for heat emergencies that provide onsite rapid cooling using cold-water immersion or an equivalent means, plus unrestricted access to water and rest breaks with unlimited hydration.
The rule directs schools to record and keep readings on file. Districts commonly retain them through at least the activity year and align with their records policy. Confirm your district's retention schedule with administration.
Keep going with the district compliance checklist, the activity thresholds, or the full Texas UIL WBGT mandate guide.
