A NewsChannel 5 Investigation discovered just how dangerous it is inside Metro's biggest high school.
Parents reacted to what was uncovered.
NewsChannel 5 Investigates discovered there were more than 400 arrests at McGavock High School last year.
Most of them were for fighting.
"A whole bunch of kids were on top of my son and he had to come in and scoop up my son out of the middle of the kids," said Carol Randall.
Her son is now in the service, but last year he had to be saved by a teacher during a large fight in the school cafeteria.
McGavock is the largest high school in the state with 3,000 students. An amateur video showed crowded halls as a teacher broke up a fight.
In 2007, Metro police arrested 435 students at McGavock. Most arrests were for fighting.
"I really don't think that size is the main issue," said Steve Glover, a Metro school board member.
He does not think cutting the number of students will solve the problem.
When asked what was the main issue, Glover said, "Society. We're not raising our children in the way that perhaps you and I were raised."
Repeat offenders account for many of the arrests. One student was arrested four different times.
This year, Metro is removing problem students from all high schools and putting approximately 600 of them into a special school for problem students.
"What it will do is it will remove that child that is disruptive because they find it challenging and it will put them in a nurturing environment," Glover said.
"If I didn't feel my child was getting a great education they wouldn't be there. I do have a choice," said David Waters.
He has three children at McGavock. He said the huge size is to their advantage.
"The advantage of the larger school is more programs," he said.
School officials said they're focused on discipline while many parents hope that will lead to fewer fights.
Parents point out that so many arrests mean the school is cracking down on fighting. Even a small fight can result in a citation and possible juvenile court appearance.
The school district is also implementing small-learning communities in the high schools. About 150 students are in each group. They have similar academic interests and share the same teachers in one area of the school.
Officials think that will cut down on some of the problems at bigger schools.
