Alvarado ISD
All 132 Alvarado High School band members will quarantine until Oct. 24 after three cases of coronavirus were confirmed within the marching band sphere.
Per the Alvarado Independent School District, two students and an educator had tested positive and the district was working to identify those who came into close contact with those individuals.
School officials said the decision to quarantine was made out of "an abundance of caution." It also came after the band participated in an outdoor pep rally Wednesday night.
"This decision was made with the safety and health of all students in mind and wanting to keep the cases and any potential exposure isolated," school officials said.
Quarantined students don't have to get tested for the virus unless they start showing symptoms, the district said on Facebook. Siblings of students quarantined inside AISD don't have to quarantine either.
According to data posted on the TEA website, Alvarado ISD had three total cases among students in grades 7-12, as of the week ending Oct. 13. It is not clear if those are the three cases on the band.
A large scare swept throughout the band. Friday night is the school's homecoming, a special evening no doubt for seniors.
Senior and Color Guard Captain Emily Geer told WFAA that when the school made the announcement--she expected she and her friends would miss what limited festivities were being held.
"This has been like one of the biggest things for my senior year that I've been waiting for," Geer said. "I felt like I wasn't going to get this memory again."
Geer's mom Brigitte tried staying positive, she knew that the district made the right move but didn't want her daughter missing out on the chance to make the memories she's earned.
"It broke my heart because I knew her heart was breaking," Geer's mom said.
"All the time and money and effort spent towards homecoming, it just made me so sad to know how devastated she was."
Some good news came late Thursday, however.
The district told WFAA that homecoming would be rescheduled after concerns were raised about the band missing their big night.
But Geer and her mother wonder if COVID-19 will impact any other senior moments.
"I feel like the whole year might be impacted by this," Geer's mom said.
Weatherford ISD
Seguin Elementary in Weatherford Independent School District moved from in-person learning to remote learning on Oct. 9.

The district will contact parents/guardians at the end of the upcoming three week period if their child has been unsuccessful with remote learning.
The district encourages parents to bring students back sooner if it is clear their student is not succeeding.
Remote learners who have been successful will be allowed to continue to learn from home.
