Despite a school-record score and a standout performance from senior Jeremy Morris, Dobie High School's Academic Decathlon team was forced to settle for the runner-up spot at the national championships, which concluded on Saturday in Charlotte, N.C.
Granada Hills Charter School won the event, giving California its ninth consecutive national title.
Dobie became the first Texas school in five years to finish in the top two - and only the second in the past 10 years.
The Longhorns piled up 50,436.2 points, the most ever for a Dobie team at the national level. Dobie won the national title in 1992 and again in 1996.
But the Longhorns' hopes for a third national championship were thwarted by Granada Hills, which finished with 52,113.5 points. The point difference - 1,677.3 - is considered razor-thin in the scoring system used.
Waukesha West (Ill.) High School took third with 49,785 points.
Morris contributed 9,059.4 points, the first Dobie student to break the 9,000-point barrier since Steven Higginbotham took over as the Longhorns' coach in 2006. Morris's score was second overall.
The Longhorns carried away 31 individual medals, the most ever won by any Texas school at the national event. Dobie also won the Super Quiz and the Super Quiz Relay.
Dobie's Quinn Velasquez went 5-for-5 in the Super Quiz Relay to secure the victory.
The Longhorns fell noticeably short in the math portions of the competition.
"We actually had a decent increase in all the other categories," Higginbotham said.
Morris won gold medals in art, literature, economics and in the Super Quiz. He also won a bronze in music.
