Addison Central School District Superintendent Peter Burrows announced the transition in a Wednesday, April 15, email to the school community. As a result of the COVID-19 pandemic, middle- and high school students have been attending in-person classes on either Mondays and Tuesdays, or Thursdays and Fridays, with the balance of their studies conducted online. Now those students will attend in-person classes each day of the week except Wednesday, when virtual learning will occur.
