SALT LAKE CITY — A bill originally seen as a way to push the Salt Lake City School District into returning all students to the classroom is now focusing on testing for students after its sponsor made major changes Friday. The language of SB107, sponsored by Sen. Todd Weiler, R-Woods Cross, was substantially altered to focus instead on requirements surrounding "Test to Stay" protocols and thresholds. The bill would require the Utah Department of Health to provide support to schools that initiate widespread COVID-19 testing under the Test to Stay program. It also establishes a 2% case threshold, up from 1% of the school population when schools must take steps to mitigate further spread of the virus, which often includes shifting to online learning.
