Katy ISD's enhanced safety protocols include use of government-approved sanitizing products commonly used in hospitals, schools and other settings. These products are significantly diluted prior to application. Safety protocols are also continuously evaluated in an effort to remain current with state, local, TEA and UIL guidance on minimizing the spread of COVID-19. We have heard the questions that have been raised regarding cleaning practices and will continue to ensure our staff feel informed and comfortable in performing their duties, as well as make appropriate adjustments, or accommodations, where needed."
