PROVIDENCE, Rhode Island - January 7, 2008 - A tech company with ties to a school district plans to test a tracking system by putting computer chips on grade-schoolers' backpacks, an experiment the ACLU ripped Monday as invasive and unnecessary.

The pilot program set to start next week in the Middletown school district would have about 80 children put tags containing radio frequency identification chips, or RFID chips, on their schoolbags. It would also equip two buses with global positioning systems, or GPS devices.

The school and parents will be able to track students on the bus, and the district hopes the program will improve busing efficiency, Superintendent Rosemarie Kraeger said. The devices are intended to record only when students enter and exit the bus, and the GPS would show where the bus was on it's route.

Parents could opt out of the program, Kraeger said.

The pilot program, made by MAP Information Technology Corp., is to run for several months at the Aquidneck School, she said. The district, which serves about 2,500 students, is the company's only client, said Deborah Rapp, the company's director of marketing and communications.

Steven Brown, executive director of the Rhode Island chapter of the American Civil Liberties Union, sent a letter to Kraeger and members of the school committee calling the plan "a solution in search of a problem" and saying the school district should already have procedures in place to track where its students are.

On Monday, he said the program raises enormous privacy and safety concerns.

"There's absolutely no need to be tagging children," he said. "We are not questioning the school district's ability to use GPS to monitor school buses. But it's a quantitative leap to monitor children themselves."
