My daughters have gone though Switched on Schoolhouse which is a computer based program. You can add some online components to it but it is not required. My eldest has graduated and did very well. She has even been looking into her doctorate. My youngest doesn't like school but she does well. This program is from a Baptist organization and is very supportive. My youngest walks herself through school everyday and I monitor it like I would a kid going to school. (It was different when they were younger.) I personally would remove my child from that situation also. It's not like when we were in school when the majority of kids simply knew who the bullies were and avoided them. They're everywhere. Your priority is your childs protection right now.
God bless,
M.
PS My sister was a student advisor in the DOD system and said this was rampant and caused many to go into deep depressions, attempt suicides and self destructive behavior like cutting and alcoholism.
