Overview

Mission

At Westridge we cultivate the extraordinary in every girl by helping them to develop the confidence, skills, and values to thrive wherever life takes them.

What it reported doing in 2024

Westridge is an independent forward-thinking girls' school in pasadena, ca committed to developing intellectually adventurous thinkers and courageous, compassionate leaders. Founded by mary lowther ranney in 1913 -- in the backdrop of the suffragist movement to give girls access to the rigors of education their brothers were getting, westridge's motto is surgere tentamus (we strive to rise); this forward-thinking mission continues to drive our work today as a school of 550 students from grades 4-12. Westridge is a space where girls are the most powerful voices in every room, they are every member of the advanced physics class or rocketry club, the most celebrated athletes, the most courageous and compassionate leaders; it's a school community where girls are encouraged to take chances, make mistakes, think deeply, and get involved. Westridge has empowered generations of girls to challenge the status quo, improve their school and the world around them, and look for ways to lead and serve their community.westridge offers an intellectually engaging and challenging curriculum, a balance of the humanities, mathematics, science, technology, visual and performing arts, and athletics. Electives and advanced courses of study allow each girl to discover and thrive within her areas of interest and strength, cultivate conceptual and critical thinking, and inspire deep learning and knowledge. The 74 members of the class of 2025 earned 686 acceptances to 179 colleges and universities. Our faculty members are subject matter experts who spend a great deal of time on their teaching and learning so that students can deeply and authentically engage with the curriculum. Faculty also serve as advisors, guiding and supporting the students in their educational journey outside of the classroom. At westridge, we know that the highest quality academic program is only valuable if students are emotionally prepared to take advantage of all that offers, and we help prepare students for learning by centering their social-emotional learning along with their sense of inclusion and belonging. Myriad student life clubs, competitive team sports, and activities give students a balance between their academic and nonacademic interests and leadership. In our classrooms, extracurricular programs, and student-life activities, we let student voices lead whenever possible so that students develop the agency and sense of self to pursue their passions and support the greater good. We are not just readying girls for the future we are giving them the practice, confidence, and self-concept that will shape the trajectory of their lives and ultimately shape the future.
