The Texas Education Agency (TEA) is the state agency tasked with overseeing public education for grades K-12 in Texas, with oversight of both independent school districts and charter schools. TEA has issued guidance on various COVID-19-related issues that affect public schools in Texas.
At the federal level, the U.S. Department of Education and the Centers for Disease Control & Prevention have also issued guidance for K-12 schools.
Most school districts have also created their own plans that outline the school's safety protocols. Check your school district's website or contact them directly for a copy of these plans.
