The coronavirus pandemic has forced colleges and universities around the country to rethink how they are teaching as the fall semester gets under way. Some are primarily online, others primarily in person. Some have hybrid plans balanced between both methods. And some are still deciding.

Adding to the uncertainty: A number of schools have said they will start online but maintain hopes of teaching in person after two or three weeks. Below is a list of 100 important public universities, their teaching strategies and their opening day for undergraduates. These schools are drawn from every state and the District of Columbia. (Wyoming has only one public four-year school.)

As of Aug. 26, nearly half of these schools were teaching primarily or fully online. Just over a quarter were teaching primarily in person. But by mid-September, the share focused mainly on in-person teaching had declined to a little more than one fifth. That is a sign of the extraordinary disruption the pandemic has wreaked in education throughout the United States. Covid-19, the disease caused by the novel coronavirus, has so far killed at least 192,000 Americans.

The source of this data is the College Crisis Initiative at Davidson College, which is tracking the pandemic response at schools around the country. The chart will be updated as information emerges about schools that have switched teaching methods.
