Early 90's, but our computer system (some sort of minicomputer) had a modem bank so that teachers could do grades and such from home. I worked in the office because I had an open hour, I earned a credit and I also got to see the guidance counselors view students records and such. It would have been very, very easy to change grades. Also, many schools had internet connections back then. I know our school had a T1, it might have also had a leased line to the state education system for some reason, I would guess the security was very lax back then.
