Schools adopting a test-to-stay program in which students were regularly tested for COVID-19 unless they proactively “opted out” of testing experienced an 84% higher testing rate and a 30% lower positivity rate than schools with a voluntary “opt-in” testing model, says a study co-written by Anton Ivanov and Ujjal Kumar Mukherjee, both professors of business administration at Illinois.
