Six female students at Soddy Daisy High School were charged with disorderly conducting after a fight broke out inside the school on Monday.
The six students were taken to the Juvenile Detention Center.
They will be suspended from school for 20 days.
Authorities said two students initiated the scuffle, then others joined in.
Teachers tried to break it up, but had difficulty getting through the crowd of students watching to do so.
Some students filmed the fight and posted it on Facebook.
