The DeKalb Central school board approved the block schedule during its meeting Tuesday evening. A block schedule replaces a more traditional schedule with longer class periods that meet fewer times each day and week. In a memorandum to the board, high school Principal Marcus Wagner and middle school Principal Matt Vince outlined the reasons they recommend staying on a block schedule. âAs we all know, the 2020-21 school year has presented many challenges and we have been compelled to make many changes as a result of COVID-19. Some of those changes have turned out to be extremely well-received by our students, staff and families. One such change was our block schedule,â the memo stated.
