We're in APS. Our son was sent home on Monday due to a cold. He is fully vaccinated and we got a negative PCR test last night, which I sent to the school's clinic and front office. Do I need to wait to be told he can come back to school? Do I just send him tomorrow? We decided to keep him home today anyway to recover fully from his cold, but not clear if I'm supposed to get some sort of response from the school before I can bring him back. My plan right now is to simply drop him off tomorrow...
