Along with Harrison, Riverton High student Andrew Johnson was also awarded the $2,000 prize, which was established to encourage students to pursue academic careers in science, technology, engineering and math.
Two national winners will be awarded $5,000 in scholarship money as well.
“These students lead the nation in performance on Advanced Placement math and science courses and we are proud to recognize them for their academic excellence,” said Jennifer Harper-Taylor, president of the Siemens Foundation, in a release.
Harrison has taken seven AP courses and lists her favorite class as calculus. She was an Energy Solutions STEM scholarship winner in 2010 and placed in the top 50 in the Utah State math Contest in 2011.
She plans to study computer science in college in preparation for a career as a software developer.
