MASSENA â It may be easier to bring elementary students back to the classroom in the Massena Central School District, but high school Principal Alan Oliver said itâs going to be more of a challenge for his building. Mr. Oliver was one of the speakers during a Monday virtual meeting to discuss the districtâs reopening plan under revised state Department of Health guidelines. âThe sad reality of it is at the high school, many of the components of the guidance really preclude us from being able to change much from what weâre doing right now,â he said. One of the changes reduces physical distancing from 6 feet to 3 feet for students in classrooms. In some cases, cohorting â a group of students who move together within that group every day â may be required.
