Correspondence study begins
IU begins offering high school courses through correspondence. By 1924, IU offers courses in eight departments in addition to university courses, especially for "those who have been unable to finish their high school work and now wish to do so."
A complete four-year high school
Associate Director E. M. Linton explains in a letter to a prospective student that “we offer practically a complete four-year high school course by correspondence" with final examinations conducted by school officials, who could travel to meet students.
Students across the world
Students from "practically every State in the Union" are enrolled in correspondence study, along with those from France, the Philippines, and Ireland. A prospective student in India expresses a desire to "share in the very spring of knowledge."
New excuses for tardiness
Director Henry A. Bern records excuses given by military students deployed on ships and in the Mekong delta in Vietnam. Due to long hours, unexpected frequency of combat, and a lack of paper in the right size, students ask for extended deadlines to complete their coursework.
200+ correspondence courses offered
Assistant Director William J. Driscoll writes to a U.S. Navy student a year and a half after his enrollment to assure "we have not forgotten about you." Over 7,500 students (housewives, retirees, teachers, disabled people, inmates) are enrolled in high school and college correspondence courses.
Telephone lines to instructors
The Wide Area Telephone Service line goes into effect, allowing students to make long-distance calls to instructors for free. This prevents students from getting behind and losing interest while waiting for mail. Indiana prisoners are now able to enroll in any IU correspondence courses.
IUHS accepts first students
Now fully accredited as a "virtual" high school, IUHS offers over 100 courses, and anyone can apply for admission at any time of year. IUHS also expands instructional techniques to include innovative technologies like the World Wide Web, videotapes, audiotapes, and CD-ROMs.
Helping K-12 educators
In response to the COVID-19 pandemic, IUHS Online works alongside Indiana K-12 educators in April to create online versions of the 40 most enrolled courses in Indiana middle and high schools, with supplementary modifications for accessibility.
A school of distinction
In 2024, IU High School is named a Cognia School of Distinction, recognizing growth in learning, a healthy culture for learning, engaging and high-quality instructional environments, and effective leadership for learning.
