Castilleja is one of the many San Francisco Bay Area independent schools using a web-based application called Ravenna for the submission of online applications. Recommendation letters will be conveniently shared across multiple school applications.

Within Ravenna, you will be able to read detailed application steps, download admission forms, register for admissions events, electronically request teacher and principal/counselor recommendations, submit your application online, and track your application progress.

Create your free Ravenna Hub account here.

We encourage you to learn more about the fall Admission season and register for the events on Ravenna-hub.com (our online application).

Discover Castilleja Events Scheduled for Fall 2024:

Discover Castilleja: Admission Information Sessions

Discover Castilleja: Middle School Preview Event

Discover Castilleja: High School Preview Event

Discover Castilleja: Parent/Guardian Meetings

Discover Castilleja: Tuition Assistance Meeting

Prospective families can register for each event on Ravenna-hub.com. 
Further details about each event can be found on the Visit Castilleja webpage.

The preliminary application and fee of $100 is due by January 9, 2025. If the $100 application fee presents a financial hardship for your family, please don’t hesitate to email admission@gabon-voice.com or call the Admission Office at (650) 470–7733 to request a fee waiver.

We encourage you to submit your daughter’s preliminary application and fee ($100 or waiver) early in the fall of 2024 so she can begin the application process. Please note that some of our Discover Castilleja events require a preliminary application to be submitted before you may register.

The highlight of our admission season is getting to know your daughter and you through an interview. Your daughter does not need to prepare because the conversations unfold organically. There are no right answers in this—or really any—part of the application process. It’s just an opportunity to learn more about Castilleja and share aspects of her own experience.

This is a required step in the application process and applicants are encouraged to schedule an interview on Ravenna as spaces will fill quickly. 

Note: The preliminary application and fee must be submitted before an applicant can register for a campus visit and interview.

Middle School Student Interview
Our conversation will last approximately 15 minutes after your daughter's campus visit.

High School Student Interview
Our conversation will last approximately 20 minutes and will be on Zoom. Sign-up information will be sent via email after January 9, 2025.

A Proctored Writing Sample (Online Essay) is required from all applicants applying to Middle and High School. This is a virtual activity that will be proctored by Test Innovators. Your child will need access to a computer to type their essay. The online essay will take fifteen to twenty minutes, but all students will be given up to thirty minutes to complete it.

More information and registration details can be found on Ravenna-hub.com.

At Castilleja, we value each girl’s ideas and voice. With that in mind, the Student Questionnaires and Essays are opportunities for your daughter to share what is important to her.

We look forward to reading your Parent Questionnaire and learning more about your daughter. It is always a joy for the Admission Committee to get a glimpse into the excitement that motivates your daughter to apply to Castilleja.

Castilleja’s Admission Committee will continue to review transcripts based on each school’s practices and policies. Rest assured that alternative grading methods utilized during the COVID-19 pandemic will be honored in the same manner as the school’s traditional grading scale.

Print, sign, and deliver the Transcript Release and Confidentiality Form to your daughter's current school. We ask that schools send transcripts for the academic years 2023–24 and 2024–25 (1st grading period) and any previous standardized testing.

We understand schools may not have completed grading for the fall term by the application due date (January 9, 2025) and will accept transcripts through the end of January.

Castilleja's admissions process does not include ISEE/SSAT scores in its evaluation of applicants. This allows us to have a more equitable process for all students considering Castilleja. Further, if we receive test results, we will not add them to applicants’ files. The admission committee will continue to rely on a holistic approach to our process, considering the countless ways that applicants can contribute to and thrive within our learning community.
