The Higher Institute of Arts and Technology (HIAT) is Merrillville's first and only charter school. We work to provide students grades K-8 with an outstanding educational experience in the arts, humanities, and sciences. At HIAT, each student is loved and encouraged to reach their maximum potential, and all of our students are scholars. Will your little scholar turn 5 by August 1st, 2021? Then, it's time to enroll!
