The school district’s investigation found “that a few students had learned the teacher’s password and then began charging a fee to manipulate grades for other students,” the district said in the statement. It added that its technology services department is working to require teachers to change passwords more frequently to “help prevent a reoccurrence.” …

All students implicated in the “grade-changing scheme” will “have to retake a required course to earn credit for it,” the school district wrote in a statement online. “For those who are seniors, graduation will be delayed until credits are completed. It will be offered as an in-person class during the summer.”
