Techheads think everything should be accessible on the internet, including student grades. Give parents a password and they can look up their child's grade any time they want.
The problem comes, of course, when that convenience comes up against the limits of technology security. What's to keep a hacker from destroying or changing grades?
And what if that hacker is the student himself?
I don't even store my grades on my school computer. I store them on removable media. If parents want to know grades, they can email me and with a few keystrokes I can send them complete details of their student's grade. It seems a small price to pay for my peace of mind.
