A lack of staffing is the reason why two grades are going virtual at Sturgeon Bay School District. In an email from Sturgeon Bay Superintendent Dan Tjernagel, the district learned that a fifth grade and an eighth-grade student from the same household tested positive for the coronavirus. Even without a positive test, a lack of staff availability was going to force the fifth grade at Sunrise School into virtual learning. That is also why the seventh grade at T.J Walker Middle School will also go 100 percent virtual for a period of time as well. Tjernagel reiterated that staff availability and the lack of substitute teachers could force other grades to go 100 percent virtual even if there are no additional positive tests. The district also learned on Friday that one more high school student tested positive for the coronavirus, which required 15 high school students and one staff member to be quarantined. Tjernagel noted that seven of the 15 close contacts occurred through a non-school community sports team.
