Marisol Castro Soto, 16, a sophomore at Akins High School, holds a student GPS tracker she uses to record her location and attendance at school in Austin, Texas. Akins High School sophomore Marisol Castro Soto said she had fallen in with the wrong crowd. She and her friends would frequently skip school or show up to classes at their leisure. But when the 16-year-old was threatened with going before a judge because of her absences, Marisol knew it was time for a change. She volunteered for the Austin school district'€™s new truancy program, which uses GPS trackers to help prompt students to go to class more often. (AP Photo/Statesman.com, Rodolfo Gonzalez)
