How Hard Is It to Get Into Junípero Serra High School?

Serra does not publish an official acceptance rate. What’s verifiable is the scale and diversity of its applicant pool: the school draws its incoming classes from more than 130 different feeder schools, and evaluates each applicant on HSPT results, teacher recommendations, transcripts, and a required student interview rather than any single metric. Families researching other selective Bay Area Catholic schools often also consider Bellarmine College Preparatory, a fellow West Catholic Athletic League member.

Top Tips for Applying

• Submit the application before attempting to register for the HSPT; registration opens only afterward.
• Request English and Math teacher recommendations early, since both are required.
• Treat the required student interview as a substantial part of the evaluation, not a formality.

Best Practices for Families

• Attend the Open House or a Padre for a Day visit before applying.
• Prepare specifically for the HSPT format, distinct from the ISEE or SSAT.
• If your son may benefit from academic accommodations, consider the optional Academic Resource Center (ARC) application well ahead of its earlier deadline.

Admissions Calendar & Key Dates

Application Requirements

To apply to Serra, you will need to submit the following:

HSPT Testing

Every student applying to Serra must take the High School Placement Test (HSPT). The exam is held on the San Mateo campus on December 5, 2026. You can only sign up for the test after you have officially submitted your school application. This test helps the admissions team understand your current academic levels in areas like reading and math.

How to prepare for the entrance exam

Preparing for Serra’s entrance exam involves more than just a quick review the night before. Students should focus on building strong habits in reading, math, and writing well in advance of the test date. Cardinal Education offers academic tutoring and test preparation to help students feel confident and ready for exam day.

Teacher Recommendations

Serra requires confidential feedback from two of your son’s current teachers. One must be from his English teacher and the other from his Math teacher. These forms are sent directly to the school to give a clear picture of how he performs in a classroom setting. It is best to ask these teachers early, so they have plenty of time to share their thoughts.

How to get the best recommendation letter

To secure a strong recommendation letter for Serra, your son should focus on being an active and helpful member of his current school. Admissions officers look for students who show leadership and treat their peers with respect. Teachers are most likely to write glowing reviews for students who participate in class and show a genuine interest in learning. This personal connection helps the admissions team see who your son is beyond his grades.

Transcripts

Transcripts are a record of your son’s past grades and school performance. You will need to provide these records from his previous school years to complete the application. Serra provides a release form that allows his current school to send these files over securely. This information helps the school see his academic growth and consistency over time.

How to improve grades

If grades have been a challenge, starting a plan for improvement early is the best way to show growth on a transcript. Consistent support through tutoring and academic coaching can help a student master difficult subjects months before the application is due. Demonstrating a steady upward trend in grades is very impressive to the admissions committee. This shows that the student is ready for the challenging high school workload at Serra.

Student Interview

The student interview is a mandatory part of applying to Serra and is a chance for the school to get to know your son personally. These meetings are held on specific dates in January and can be done in person or over Zoom. Your son should be ready to talk about what he likes to do and why he wants to join the Serra community. Preparing for this interview is a great way to ensure he makes a memorable and positive impression.

How to prepare for the admissions interview

It is helpful to think of the Serra interview as a friendly conversation rather than a high-pressure test. Students should feel comfortable sharing their unique interests, hobbies, and goals for high school. Parents can also support this process by discussing why they believe Serra is the right environment for their son. Cardinal Education’s interview preparation helps students speak with confidence and be themselves during this important meeting.

Optional Components

Families may optionally apply to the Academic Resource Center (ARC), a learning-support program requiring IEP, 504, or psycho-educational documentation. An optional Clergy Recommendation Form is also available.

The Tri-School Consortium

Because Serra is an all-boys school, it partners with Mercy High School and Notre Dame High School to create the Tri-School Consortium.

It allows students to experience a coed social life while still enjoying the focused environment of an all-boys education. It is truly the best of both worlds for many families.
