Two Janesville Schools will be extending online instruction under guidance from the Rock County Health Department.  District officials say Craig High School and Roosevelt Elementary will remain closed to face-to-face instruction and extend their online instruction for an additional week through October 2nd.  Both schools went to online instruction just last week.  In a letter to parents Tuesday morning, principals of both schools said the extension of online instruction is due to continued follow-up with close contacts of established positive COVID-19.
