Indiana

Indiana has been one of the largest participants in Science Olympiad for many years now, claiming 2 slots at the national competition until 2015. Two National Tournaments have been held in this state as well, both of which occurred at Indiana University Bloomington (always referred to as "IU" by Indiana residents) in 1995 and 2006.

History
The state is home to national champion Thomas Jefferson Middle School, which won in 1993.

Thomas Jefferson Middle School has dominated the B division for most of its existence, though Batchelor and Ben Franklin have been known to make runs in the past. The Stanley Clark School, Wilbur Wright, Tri-North, Raymond Park Middle School, and Chesterton Middle School have been rising new challengers in recent years. In 2019, both Thomas Jefferson and Raymond Park set the record for lowest scores. Thomas Jefferson won 1st with 50 points, and Raymond Park got 2nd place with 66 points. Both state records.

In division C, Bloomington High School North, Bloomington High School South and Valparaiso High School have programs with extensive histories, almost always placing in the top 10 at the state tournament in any given year. Other historically strong programs include Carmel High School and North Central High School.

In recent years several northern Indiana schools have become significant contenders, most notably Northridge High School and Munster High School - each of which have won a state championship. Lake Central High School and John Adams High School have also become contenders in the last 5 years. In 2018, Lake Central placed 2nd at the state tournament (after placing 4th from 2014 - 2016 and 3rd in 2017) and John Adams broke into the top 5.

In 2013 Munster High School dominated the state tournament winning by a record-breaking margin of 79 points under the 2nd place school (Bloomington High School North). They went on to win the 2014 State Championship, and then recently the 2015 State Championship. In 2015, they broke the previous state record with a score of 61, and also broke the record for most golds won (11). In 2017, they broke their own record again, scoring only 59 points at the state tournament. At the 2015 National Science Olympiad competition at the University of Nebraska-Lincoln, Munster High School placed 6th in the nation overall, one of the highest placing Division C teams in Indiana history.

Past State Champions
This is a record of the past state champions and runners up, and their respective places at the national competition. Scores at the state competition shown in parentheses.

Note: Starting in 2015, Indiana is no longer sending two teams per division to nationals. This was due to WV's revival of their Science Olympiad program and Indiana's stagnation in number of teams participating relative to the other states that year and in those that followed.
