JACKSONVILLE, Fla. -- U.S. News & World Report is out with its first-ever high school rankings, and while Duval County's top two academic magnet schools made the magazine's top 100 list, they didn't earn the grades awarded by Newsweek's recent lists.

Using K-12 data research and analysis business run by Standard & Poor's, the magazine put high schools in 40 states through a three-step analysis. U.S. News and World measured how each school's students performed on state tests, adjusting for student circumstances. Then it evaluated how well each school's disadvantaged students did. Lastly, it looked at whether the school was successful in providing college-level coursework.

The magazine's analysis considered more than 18,500 high schools in 40 states.

The magazine's first rankings give the top honor to Fairfax County's elite Thomas Jefferson High School for Science and Technology -- one of three Virginia schools on the list.

Four Florida schools were in the list's top 10, with Florida Oxford Academy in Bartow at No. 3, Sarasota County's Osprey High Technology High School at No. 6, Miami-Dade High School at No. 8 and Jacksonville's Stanton College Prep at No. 9.

Newsweek magazine has consistently ranked Stanton in its top five -- No. 3 last year. U.S. News ranked Paxon School For Advanced Studies No. 30, while it was No. 17 on Newsweek's 2007 list.

The report was posted on the U.S. News & World Report's Web site on Friday, and will be printed in its Dec. 10 edition.
