North Wasco County School District 21 Interim Superintendent Theresa Peters says the district is working on ways to increase the number of students and the amount of time for in-person learning while maintaining safety requirements.  In a letter to parents issued on Friday, Peters says updated guidance from the Oregon Department of Education allows for three-feet of physical distancing in classrooms under certain conditions, but they still must maintain six-feet in other situations.  Peters adds challenges they face include classroom size limitations, serving meals while maintaining the six-foot distancing requirement, staffing issues, and busing implications for school schedule changes.
