"Once again, Thomas Jefferson High School for Science and Technology in Fairfax County, Virginia, has been named the No. 1 high school in the U.S.
Senior data analyst with U.S. News & World Report Eric Brooks said some of the things that put Thomas Jefferson on top include a nearly 100% graduation rate, and the fact that every senior took advanced placement exams and got a score of three or higher.
As far as statewide testing goes, Brooks said, “All their students are proficient at reading and math.” Thomas Jefferson also does very well in U.S. News’ science, technology, engineering and math ranking, which looks at performance on AP exams in science and mathematics.
Two other local schools rank in the top 125 high schools nationwide. School Without Walls in D.C. ranked 90th nationally and No. 1 in the city. Walt Whitman in Montgomery County, Maryland, ranked 111th nationally and No. 1 in Maryland. Brooks said these two schools have graduation rates in the high 90s and students do well on AP exams and state"
"Nine of the top 10 ranked schools in Virginia are in Northern Virginia. The reason is Virginia schools have relatively balanced numbers of students testing as proficient in reading and math, but school districts, such as Arlington, Fairfax, Prince William and Loudoun counties, graduate students who are about 80% to 90% proficient in the subject areas.
Schools that made the top 25 in Virginia from Fairfax County include Langley, McLean, Marshall, W. T. Woodson, Chantilly, Oakton, Madison, West Springfield, Robinson, Lake Braddock and Centreville."
