Schools Use Covid-19 Tests to Keep Students Out of Quarantine – The Wall Street Journal

Some schools are trying a new plan to keep students safely in the classroom: Rather than quarantining children who have an in-school contact with a positive case, they are testing them. A lot.

The method keeps children in school after exposure to a classmate or teacher who tested positive for Covid-19 if they test negative at least every other day. Known as test-to-stay, the approach is a higher transmission risk than keeping exposed students at home, but some public-health experts and educators say the trade-off is worth it to avoid missed days in class.
