Of the student cases, 508 were hybrid students, 348 were in-person students, 274 cases were remote students and 16 were unknown.
As cases of COVID-19 rise, several schools have reverted back to distance learning and some plan to stay that way into January.
One hundred forty-five Connecticut cities and towns have reached a red-alert level, the highest level, due to cases or coronavirus.
