Schedule Campus Visit

Campus Visits give girls a chance to spend a day on campus. Hosted by a Castilleja student, it is a great opportunity for your daughter to meet students, visit classes, eat lunch, explore the campus, and have fun!

Campus Visits will be offered from late September-mid December.

Applicants for 6th grade will also participate in a group activity session on the day of the Campus Visit.

Please register on Ravenna.

Register for Standardized Testing

Castilleja requires standardized testing as part of our admission process in order to gain a better understanding of each applicant. We receive applications from many schools with a variety of academic programs, and test results provide a common denominator.

Test results are just one of many factors we consider when evaluating an application and are by no means the only measure of a student’s capabilities. This information is used along with other application materials when making admission decisions. The Admission Committee values many personal qualities that are not gleaned from multiple-choice tests. These include creativity, humor, motivation, patience, perseverance, and compassion, to name a few.

Required Tests

Grades 6-9:  Independent Schools Entrance Exam (ISEE) or Secondary School Admission Test (SSAT)

Grades 10 and 11:  ISEE, SSAT, PSAT (Preliminary Scholastic Aptitude Test), or SAT (Scholastic Aptitude Test)

Testing Locations

ISEE:  Will be offered at Castilleja on December 7, 2019 and January 4, 2020.

If a student is unable to test at Castilleja on one of these two dates, she may take the exam at another test site. Please contact ERB for test sites and dates. SSAT and PSAT are not offered at Castilleja.

Registration Information

ISEE: Register for the exam at Castilleja's school code is 052330.

SSAT: Register for the exam at Castilleja's school code is 2152.

TIP! Register for the ISEE test as early as possible in order to secure your first choice test date. The ISEE may be taken at any testing location.

If you need a fee waiver to cover the cost of the ISEE or SSAT, please contact Laura Martinez at 650.470.7732.

Ask for Recommendations

For Middle School applicants, recommendations are required from the current Core/Language Arts teacher, prior year Core/Language Arts teacher, and Principal/Counselor.

For Upper School applicants, recommendations are required from the current Math and English teachers and Principal/Counselor.

You will find the necessary link to request recommendation forms on your Ravenna account.

TIP! It is best to wait until the school year is underway (mid-November) before asking for recommendations so teachers and counselors will have ample opportunity to get to know your daughter.

Send Transcripts

Deliver the Transcript Release and Confidentiality Form to your daughter's current school.

You will need transcripts for the past academic year and the first grading period of the current academic year.

The Transcript Release and Confidentiality Form can be downloaded from your Ravenna account.

Complete the Application, Essay, and Questionnaires

Submit your application through Ravenna by January 9, 2020.

Learn More about Tuition Assistance

We encourage families who can not afford the full cost of tuition to apply for Tuition Assistance.

Applications for Tuition Assistance have no bearing on whether or not an applicant is admitted and all inquiries are kept confidential.

If you are interested in applying for need-based tuition assistance, more information can be found here.
