Schools say iPods becoming tool for cheaters

Banning baseball caps during tests was obvious -- students were writing the answers under the brim. Then, schools started banning cell phones, realizing students could text message the answers to each other.

Now, schools across the country are targeting digital media players as a potential cheating device. Devices including iPods and Zunes can be hidden under clothing, with just an earbud and a wire snaking behind an ear and into a shirt collar to give them away, school officials say.

"It doesn't take long to get out of the loop with teenagers," said Mountain View High School Principal Aaron Maybon. "They come up with new and creative ways to cheat pretty fast."

Mountain View recently enacted a ban on digital media players after school officials realized some students were downloading formulas and other material onto the players.
