In September 1987, a student shot and wounded a teacher at the school. The student, who had been removed from the soccer team for smoking cigarettes on campus, shot the teacher who turned him in.[6]
In March 2014, Illiana decided to move to St. John, Indiana (approximately 12 miles to the southeast). The reasons given for the move include the need for larger and more modern facilities and grounds as well as the migration of many of the school's families to Northwest Indiana. On April 21, 2016, the Illiana Christian High School Association purchased a 37 acres site in St. John for $833,208.75.[7][8] On November 5, 2016, groundbreaking for the new school property located on the corner of 109th Ave and Calumet Ave (also known as "Shoe Corner") in Hanover Township was held.[5]
The new campus opened with the beginning of the 2018-19 school year.[9]
The demographic breakdown of the 472 students enrolled for 2017-18 was:[1]
