Polytechnic School, often referred to simply as Poly, is a college preparatory private day school located in Pasadena, California with approximately 850 students enrolled in grades Kindergarten through 12. The school is a former member of the G20 Schools group. History The school was founded in 1907 as the first non-profit, independent school in Southern California. It descends from the Throop Polytechnic Institute founded by Amos G. Throop, the same institution that grew into the present California Institute of Technology. In the spring of 1907, the Institute decided to focus on the college level and closed the grammar school. Citrus tycoon and noted eugenicist Ezra S. Gosney donated $12,500, a sum matched by twelve other donors. This money allowed them to purchase the property at the present site, originally an orange grove. The school opened in October 1907 with 106 students. At the time, the school was named Polytechnic Elementary School. The school added a ninth grade in 1918 and expanded to high school in 1959. Polytechnic ended its pre-kindergarten program in 2005. Academics Poly is recognized for its rigorous academic curriculum, which includes Advanced Placement and Honors classes as well as arts and athletic programs. The school has received numerous accolades for the academic accomplishments of its students. In 2006, Poly was named a world leader in student participation and performance on Advanced Placement exams by the College Board. The school frequently had the highest percentage of its students receive a 3 or above on the AP Calculus AB examination when compared to all other small schools administering the test across the globe, according to the College Board. In recent years, the most popular college destination for Poly students was the University of Southern California. The Wall Street Journal ranked Poly 4th in the world as a feeder school for "elite colleges," including Harvard University, Princeton University, Massachusetts Institute of Technology, Williams College, Pomona College, Swarthmore College, the University of Chicago and Johns Hopkins University. In the 2016-17 class, 35% of the class were National Merit Semi-Finalists & Commended students and 80% of students were accepted to 'highly-selective' top tier universities (institutions with an admit rate of 30% or lower). Los Angeles Magazine has also consistently recognized Poly as one of the best high schools in Los Angeles.
