Former Massachusetts Education Secretary Paul Reville spoke to Boston Public Radio on Thursday about the timeline for reopening schools amid the pandemic.

“It’s clear that for the balance of this semester, we’re not going to have in-person education fully restored in any of our big cities,” he said. “The fall [semester] is still an open question and depends how far we can penetrate with the vaccine.”

Paul Reville is former state secretary of education and a professor at Harvard University’s Graduate School of Education, where he also runs the Education Redesign Lab. His latest book is "Broader, Bolder, Better: How Schools and Communities Help Students Overcome the Disadvantages of Poverty."
