Police say Catherine Venusto, a former employee of the Northwestern Lehigh School District in New Tripoli, Pa., hacked into the school's computer system to change her children's grades, the Morning Call reports.

According to the paper, court records show Venusto's daughter went from a failing grade to having a "medical exception," and her son's grade of 98 rose to 99.

The Associated Press reports Venusto admitted to changing the grades, though she maintained her actions were simply "unethical" -- not illegal.

On the Northwestern Lehigh School District website, Superintendent Dr. Mary Anne Wright released a statement about the incident:

“The District assisted the Pennsylvania State Police in efforts to identify and apprehend the person responsible for this incident.The acts were intentional, criminal action to obtain protected information. We deeply regret this incident and that this unauthorized access occurred, and we sincerely regret any inconvenience this may cause. We are doing everything we can to prevent this from happening again, and new security procedures are in place to better assure that our systems are protected from such attempts.”

The Morning Call reports Venusto was released on $30,000 bail after being charged Wednesday with three counts each of unlawful use of a computer and computer trespassing.
