Topsham-based school district ramps up in-person learning Grades 4 and 5 will join grades K-3 later this month, returning to school four days a week. Screenshot TOPSHAM — Maine School Administrative District 75 will increase fourth- and fifth-graders’ in-person learning days from two to four days a week starting Feb. 22, Assistant Superintendent Amanda Hersey told the school board Thursday. The district has been increasing in-person learning incrementally, starting with the youngest grades, since December 2020. The school board has continued to debate whether it should bring students back to school full-time and, if so, how quickly. In the meantime, students continue to participate in a mix of in-person and remote learning. The district has also offered a remote-only option for students.
