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.

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, and Chesterton Middle School have been rising new challengers in recent years.

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 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 tournnament. At the 2015 National Science Olympiad competition at the University of Nebraska-Lincoln, Munster High School placed 6th in the nation overall, the highest placing Division C team 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: Indiana typically sends two teams per division to nationals; however, in 2015, due to WV's revival of their Science Olympiad program and Indiana's slower increase in participation, Indiana's number of teams to send to nationals was cut from two to one per division, so despite second place finishes in the B and C divisions, respectively, Chesterton Middle School and Carmel High School did not get the chance to compete at the 2015 National Tournament.
