Castilleja School

Castilleja School is an independent day school for girls in grades 6 through 12, located in Palo Alto, California. Enrollment sits between 300 and 500 students, and the school has no religious affiliation. Its mission is to educate motivated young women to become confident thinkers and compassionate leaders who work to effect change in the world.

Teaching at Castilleja means working with students who arrive curious and well prepared. The setting in Silicon Valley shapes what happens in class, especially in STEM, and connects faculty to a region engaged with research, technology, and civic life. Language offerings include Mandarin, French, and Spanish, alongside a full humanities program.

Because Castilleja is a day school, faculty are not asked to dorm or hold evening duty. Most teachers still advise a group, coach or sponsor an activity, and join the school's work on student wellness — a real priority in this academic community. Class sizes are small, and department teams tend to plan curriculum together rather than in isolation.

The finances matter for anyone weighing stability. Castilleja School reported net assets near $147 million and revenue of about $34 million in 2023, with fundraising up roughly 17 percent. Those numbers support competitive Bay Area salaries, health and retirement benefits, and funded professional development.

Castilleja hires across academic departments, admission, advancement, athletics, student life, and operations. Faculty jobs cluster before the school year; staff roles post year-round. Palo Alto housing is costly, so weigh total compensation carefully.
