In January, when the Baker administration announced a new pooled COVID-19 testing initiative for K-12 schools, Education Secretary James Peyser said technological advances had enabled the state "to take our testing program to the next level." Three months later, with 185 of 400 school districts participating and the state now planning to pick up the tab through the end of this academic year, some of those involved are looking a level beyond, eyeing the Massachusetts program as a potential national model. "We've already had other states ask us if we could replicate the program," said Tim Rowe, the co-founder and CEO of CIC Health, one of the pooled testing providers. "We're expecting most states, perhaps all states, will do this."
