The program is designed to keep kids exposed to the virus in school as long as they continue to test negative.
More than 400 students have been tested since Sept. 27, and only four of them had positive results, according to the Lexington Herald-Leader.
“One of my top priorities is ensuring our students are able to attend school in-person and we will keep doing what works,” said Fayette County Superintendent Demetrus Liggins Tuesday night in a letter to families.
Eight schools are currently using “Test to Stay” in the district.
Kids exposed to the virus outside of schools are not eligible.
