The Tri-Cities Prep Mock Trial team won 1st place at the YMCA Youth and Government Mock Trial District Competition in February.  Two teams from the district competition advanced to the state competition that was held this past weekend.  Of the two Tri-City high schools competing at state,  Tri-Cities Prep placed the highest! The YMCA Youth and Government Mock Trial program is a unique blend of law, debate, and drama in which students learn about topical issues and courtroom procedures while sharpening their critical thinking and public speaking skills.  The trials are not scripted and are held in real courtrooms with real judges. Tri-Cities Prep has taken part in the Mock Trial program since 1999, competing at the state-level for 14 out of 17 years.  Unlike sports leagues, the mock trial program does not divide similarily sized schools into competetive leagues.  This means that Prep often competes against schools with much larger student populations […]
