IAU operates on a semester calendar that starts in fall and ends in summer. There are two semesters (Fall and Spring) per calendar year and one Summer vacation. One semester is 16 weeks. However, each semester is divided into two sessions, each eight weeks long.
| FALL (Sep-Dec) | SPRING (Jan-Apr) | SUMMER (May-Aug) |
| Session 1 (Sep-Oct) | Session 1 (Jan-Feb) | Session 1 (May-Jun) |
| Session 2 (Nov-Dec) | Session 2 (Mar-Apr) | Session 2 (Jul-Aug) |
Each course is 8 weeks. A course is broken into 8 Lesson intervals to measure Satisfactory Academic Progress (SAP). Therefore, each Lesson is completed in 1 week. This gives opportunities for the professor to guide, assist, and support students’ learning process. Within each Lesson, a student will be provided instructions and details as to how to complete the Lesson. Each Lesson is comprised of various activities or assessments to measure students’ level of mastery of various subject areas. Specific Chapters are assigned to read, discussion questions to be completed, or case studies to be analyzed.
