2017 St. Mark's School of Texas Invitational

The 2017 St. Mark's School of Texas Invitational was held on February 25, 2017 at St. Mark's School of Texas in Dallas, using NAQT's IS-164 set.

The initial submitted results showed Windhaven Park E as the winner of the tournament, with a 9-0 record. NAQT determined that there was "a statistically anomalous performance by the Windhaven Park E team given its members’ previous tournament experience." NAQT offered the team the opportunity to demonstrate proficiency in quiz bowl in a Skype match, but the team declined. Consequently, NAQT vacated the wins of all Windhaven Park teams, rescinded the school's HSNCT invitations from previous tournaments, and banned two players from the Windhaven Park E team.
