Researchers at the data research company Mathematica have created an interactive website to help school officials consider their options for coronavirus testing. The COVID-19 K-12 School Testing Impact Estimator uses data from around 335 schools and school testing sites in several states from the 2020-21 school year to predict the effectiveness of different testing strategies.

"We essentially modeled hundreds of different routine testing scenarios based on what schools in our pilot sites were implementing or considering implementing in terms of who they were testing and how often," says Mathematica's Divya Vohra. "We ran hundreds of simulations across hundreds of different combinations of routine testing scenarios, and we put all of that together in this interactive impact estimator."

The estimator allows for comparisons of different testing strategies for key outcomes, such as the number of in-school transmissions prevented or lost days of school due to quarantine and isolation.
