Police launched an investigation after a routine audit in September led to an employee noticing differences between online grades and paper transcripts.
Michael Nuzzo, director of security in the kindergarten-to-12th-grade district, located in a largely affluent suburb of Philadelphia, said in a statement that the two suspects did not "hack" into the system but "gained access through the unauthorised used of passwords."
Susan Bastnagel, a district spokeswoman, told SCMagazine.com today that she did not not know how the suspects came across the privileged passwords, but she said staff will be reminded to better protect them.
"I'm not sure if somebody left the computer logged on or if it was written on their desk, but it was just [someone] not [being] careful," she said. "I think they [IT administrators] had everybody change their paswords soon after"
Guidance staff at the high school where the incident occurred have since reviewed transcripts to ensure their accuracy.
"We want the message to be very clear," Superintendent David Campbell said. "This type of activity will not be tolerated."
Just last month, a high school class president in Florida was arrested and charged with two counts of computer crime with the intent to defraud, a second-degree felony, for allegedly using privileged password access to change the grades of 19 students.
