Granada Hills Charter High School took top honors at the 2011 U.S. Academic Decathlon, besting competitors from all over the country.
Officials say the nine-member team won Saturday by a wide margin, with 52,113.5 points out of a possible 60,000, beating second place Dobie High School from the Houston area.
The big win in Charlotte, N.C., came after days of testing in math, social science, economics and other subjects. Thirty-five high schools participated.
A Los Angeles Unified School District school has now won the event for a record 12th time.
