Texas Student Tracking Chip Suit Back in Court The family of a 15-year-old student fighting the use of tracking badges in her San Antonio high school is asking a federal court to keep her on campus. The Northside school district equipped 4,200 students this fall with mandatory ID badges containing tracking chips. Administrators say locating students via computers will improve safety and boost attendance records that are used to calculate how much state funding a district receives. Sophomore Andrea Hernandez has refused to wear the badge, and the district says she must transfer to another campus if she doesn't comply. A San Antonio federal court Monday is set to hear the family's request to stop the district until the lawsuit is settled. Northside ISD is the fourth-largest school district in Texas.
