Schools in the Tennessee Valley continue to navigate COVID-19 Valley schools COVID-19 update By Tiffany Thompson | January 27, 2021 at 11:34 PM CST - Updated January 27 at 11:35 PM HUNTSVILLE, Ala. (WAFF) - On Wednesday, 150 Discovery Middle School students in Madison are still in quarantine after potential exposure to COVID-19 earlier this week. Then, you have Arab City Schools leaders extending its blended learning model through February 12th because of safety concerns. Over in Madison County, students learning traditionally return to campuses for five days a week on Monday. It’s clear the juggling act for districts navigating this virus continues. Limestone County School District Superintendent Dr. Randy Shearouse said the numbers are looking better, but still not where he wants them.
