Authorities in Caddo Parish say 18 senior students at Southwood High School face disciplinary action for allegedly hacking into an online class to change their grades.
School system spokesman Victor Mainiero tells KTBS-TV the investigation began last week and centers on a class offered only online.
The students have been suspended and could face expulsion, he says. Officials did not release their names or details of how the students were able to change the grades.
