OSWEGO â Plans unveiled Tuesday by the Oswego City School District would see all students from pre-K through grade six in schools four days per week beginning Monday and all students would have extended school day hours. A letter released by Superintendent Dr. Mathis Calvin III laid out new plans, including learning in schools for all elementary students who have selected the in-person model on Mondays, Tuesdays, Thursdays and Fridays. Calvin, who noted officials hope to begin implementing the new plans next Monday, April 26, said it was a âvery exciting announcement.â âI appreciate all the hard work our officials have put in to put this plan together so quickly after new state guidance threw a wrench in the plans a little over a week ago,â the superintendent added. âWe are ready to do what we have set out all along for: Bringing our kids back for expanded in-person learning.â
