The **Knowledge Master Open (KMO)** is a computer-based academic competition created and run by **Academic Hallmarks**. In this contest, school-based teams answer a large set of multiple-choice questions covering math, science, social studies, language arts, geography, fine arts, current events, and more. Teams compete during designated testing windows, and their performance is scored and ranked against other schools across the United States (and historically, some international schools). KMO is typically organized by schools (rather than individual students), with teachers or coaches registering a team and administering the contest using provided software and materials. The format emphasizes teamwork, broad academic knowledge, and quick, strategic thinking. Participating students gain experience in buzzer-style academic competition, reinforce classroom learning, and build collaboration skills while seeing how their school stacks up in regional and national rankings.
