BASIS Tucson and Canyon del Oro High School were named two of America's best high schools by Newsweek magazine.
Slightly more than 1,600 schools nationwide were recognized this year.
BASIS Charter was ranked sixth and CDO was ranked 1,571. CDO is the only traditional public high school in the Tucson area to be recognized.
BASIS Tucson's high school program is advanced placement-based, meaning all students are required to take AP courses and exams as a part of the core curriculum. Students must take at least eight AP courses and six AP exams in order to graduate.
While students at most American high schools cannot begin taking AP exams until 11th grade, BASIS students are required to take their first AP exam in 9th grade and may take AP elective courses as early as 8th grade.
Since 2005, CDO has consistently been academically classified as "Excelling" by the Arizona Department of Education, placing it in the top 10 percent in Arizona.
In 2009, BASIS Tucson ranked ninth nationally, and was the only Arizona high school with 100 percent of its students meeting state standards in all subjects of the Arizona Instrument to Measure Standards exams.
