Montana

Montana consistently sends one team to the national tournament from each division. It hosts its state tournament in the fall, rather than in the spring.

History
Montana Science Olympiad began 25 years ago with only 20 teams attending the first state competition. In 1988, three years after Montana SO began, it began awarding trophies to the champions of a small school division.

Past State Champions
This is a record of the past state champions and runners up, and their respective places at the national competition, if applicable. Note that the years listed in the table are the years in which the corresponding teams attended the national tournament. These teams would have won the previous year's state tournament, as Montana holds its state tournament in the fall.

Competitions
Montana does not have regional competitions. It only has a state competition.
