What are the requirements for being full time virtual?

I opted for my student to be full-time virtual at another school during COVID. Now, I want them to return to school for face-to-face instruction at Harrelson. What is the timeline?

My student missed the bus or has an orthodontist appointment, etc... isn't that the same as quarantined absences? Can they just attend virtually and be present?

How is attendance taken and counted for quarantined students?

I got a truancy letter but my child was quarantined?
