- The inaugural state math contest took place on May 2, 1981 at Illinois State University. The contest would remain at ISU until 2000, when it would move to University of Illinois.
- 1331 students from 32 Division A schools (<750 students) and 69 Division AA schools (>750 students) participated.
- The contest was sponsored by ICTM and CNA Insurance Companies. CNA would remain a sponsor of the contest until 1993.
- Topics at the state finals were:
- Algebra 1, Geometry, Algebra 2, Pre-Calculus (20 questions, 1 point each)
- Calculator Team (5 person, all levels) (20 questions, 5 pts each)
- Ten Person Team (1 team, 5 FS, 5 JS) (20 questions, 5 pts each)
- FS 2 Person Team (10 questions, max score 60 pts)
- JS 2 Person Team (10 questions, max score 60 pts)

- JS Relay (2 teams per school) (3 rounds, max score 30 pts)
- 2 Oral Topics per division
- Awards given to top five in each event, and top five overall teams
- Scoring is done by hand at the regional level. A custom Apple II-e based scoring program written by ISU faculty is used at the state finals.
