Bebras is a free international computational-thinking challenge where students solve short logic and informatics puzzles in one 45-minute sitting during a set window each fall. A teacher registers as a coordinator and creates student accounts; high schoolers fall into the Juniors (ages 14-16) or Seniors (ages 16-18) category and get age-appropriate tasks, with results showing how a student's computational thinking compares nationally and internationally.
