Region IX (DFW) of the Texas Academic Decathlon is considered one of the stronger regions in the state, home to the consistently high-performing Chester W. Nimitz High School and consistently placing multiple teams in the top ten at State. In the 2014 competition season, Region IX tied for the second-highest number of Large Schools sent to State (4) and sent the highest number of Medium Schools to State (5) of any region.
Region IX has featured only one live Nationals Competitor: Keller High School won the region and the state in 2005 to take fifth place at Nationals. The previous year, Nimitz High School, despite winning the Large Schools State Championship, was beaten in score by Friendswood High School (a Medium School) and thus did not attend Nationals. Also, in 2008, Pine Tree High School was selected to represent Texas at Medium Schools E-Nationals; the team placed second overall.

With an overall increase in scores compared to previous years, it was no suprise when Nimitz won the competition with 46,001 points; what was suprising was the margin of victory - Marcus missed taking the title by only 1,088 points with a 44,913. The two schools ranked 2nd and 7th going into State. For the fifth year in a row, the Region sent 5 schools to State: Flower Mound (42,941), Creekview (42,833), and Coppell (38,777) rounded out the top five. At State, Nimitz maintained 2nd and Marcus maintained 7th. Flower Mound moved up from 12th to 11th, Creekview dropped down from 13th to 16th, and Coppell improved from 38th to 30th.
Hosting its first Medium School competition ever, Region IX announced its entrance to state with a bang. Six schools advanced to State, the most sent by any region. Centennial High School (41,563), was honored with the Regional title, and Pine Tree (40,923.5), Frisco (40,565.9), McKinney North (35,697.7), The Colony (34,955.9), and McKinney Boyd (34,835.1) all qualified for the State championship in San Antonio. The teams entered ranked 7th, 8th, 9th, 17th, 20th, and 21st, respectively, and left the State competition ranked 8th, 7th, 9th, 18th, 17th, and 19th, respectively. Because all other higher-scoring Medium Schools were too large for USAD Medium School competition, Pine Tree was selected as the Medium School representative for Texas at the 2008 USAD Medium School Virtual Nationals. Pine Tree placed second out of 13 competing schools.
2007 was yet another victorious year for Nimitz High School. The Nimitz team took first place with 43,451 points and was ranked fifth across the state based on Regional scores; at State, Nimitz placed second. Keller took second place with 41,130 points and ranked 10th; the school improved to 6th at State. Marcus (39,855), Flower Mound (38,163), and Creekview (37,806) rounded out the top five and advanced to State. 2007 was the first year for Flower Mound to advance to State, where the team placed 10th, up from 26th; Flower Mound was also the most-improved Large School team from Regional to State, increasing in score by 3,125 points. Marcus dropped from 17th to 18th at State and Creekview improved from 29th to 20th.
Despite winning State in 2005, Keller could not hold on to its Regional title. The Nimitz team took first place with 42,141 points and was ranked seventh across the state based on Regional scores; at State, Nimitz placed fourth. Marcus took second place with 41,487 points and ranked 10th; the team held its 10th place spot at State. Creekview (40,421), Keller (39,815), and Fossil Ridge (39,348) rounded out the top five and advanced to State. Creekview improved to 7th place from 14th, Keller moved up to 11th place from 18th, and Fossil Ridge dropped to 25th from 20th.
For the first time since Nimitz had joined Region IX, it did not win the Regional title. Instead, Keller High School took the coveted title, with a score of 44,584, giving it a 2nd overall rank across Texas. At State, with a score of 46,783, the team managed to beat out tough competition from Lubbock, Holmes, and Plano Senior to give Region IX its first National appearance ever. There, Keller took 4th place with 45,879.6 points. Nimitz took second place with 41,982 points and ranked fifth. Though the team improved to 43,393 points at State, it fell back to sixth place. Creekview (41,413), Marcus (40,068), and Fossil Ridge (38,850) rounded out the top five and advanced to State. Creekview dropped from 7th to 10th place, Marcus maintained 13th place, and Fossil Ridge dropped to 22nd from 20th at State.
For the seventh year in a row, though moved from Region X to IX, Nimitz won its regional meet with 46,549 points and advanced to the State Competition. Ranking first in the State among Regional scores, it was no suprise when Nimitz won the Large School State competition with 45,811 points. Unfortunately for Nimitz, the school was deprived of a National appearance due to its lower score than Medium School champion Friendswood High School. Fossil Ridge took second place with 41,831 points and ranked 11th. The team dropped to 39,897 points and 18th place at State. Marcus (41,345), Creekview (41,153), and Keller (40,966) rounded out the top five and advanced to State. Marcus improved from 13th to 9th, Creekview dropped from 14th to 17th, and Keller improved from 16th to 12th at State.
