Quick Answer for Busy Parents
Applying to Flintridge Prep involves six steps: an inquiry form, an optional campus visit, the online application, transcripts, three recommendations, and a final testing and assessment stage. That last stage splits by grade — applicants to grades 7–9 complete a writing reflection and classroom visit, while grades 10–11 complete an individual interview instead. All applicants take the ISEE or SSAT, though grades 10–11 may substitute a PSAT, SAT, or ACT score.
The Six-Step Application Timeline
Most of the Flintridge Prep application runs through the school’s online applicant portal, but the steps happen in a specific order, and several depend on people outside your household finishing their piece before your deadline.
- Inquiry form — adds your family to the admissions mailing list and unlocks portal access. No fee, no commitment.
- Campus tour or open house — optional, but the fastest way to judge fit; booked through the school’s Visit Us page.
- Online application — academic history and extracurricular details, submitted through the portal.
- Transcripts — official records from your child’s current school, typically the last two to three years.
- Recommendations — three required letters (detailed below).
- Testing and assessments — the ISEE/SSAT, the Character Skills Snapshot, and a grade-specific component.
The portal tracks your application, but it doesn’t automatically chase down a transcript request sitting in a school registrar’s queue or a recommendation a teacher hasn’t started. Those pieces need their own lead time, independent of when you personally submit your part.
What Changes by Grade Level: Interview vs. Classroom Visit
This is the step families most often get wrong, because the checklist looks identical on the surface for every applicant until this point.
| Requirement | Grades 7–9 | Grades 10–11 |
| ISEE or SSAT | Required | Required, unless substituting a score below |
| Alternate test score | Not applicable | May submit PSAT, SAT, or ACT instead |
| Character Skills Snapshot | Required | Required |
| Writing reflection | Required | Not required |
| Classroom visit | Required | Not required |
| Individual interview | Not required | Required |
The writing reflection and classroom visit give admissions a sense of a younger applicant in an actual academic setting — how they write unscripted, and how they behave in a room they didn’t choose. The individual interview, for grades 10–11, replaces both with a direct conversation, on the assumption that an older applicant can speak for themselves.
Where Families Lose Time: Transcripts and Recommendations
Two steps depend entirely on other people’s schedules, which is exactly why they’re the ones most likely to slip past a deadline.
Transcripts come from your child’s current school registrar, and most offices need one to two weeks to process a request, longer during peak admissions season, when every applying family is asking at once. Request transcripts the day your application opens, not the week it’s due.
Recommendations require three separate letters: your child’s current math teacher, current English teacher, and a school administrator, such as a counselor or principal. Administrators, in particular, are often writing several of these in the same window, so give every recommender several weeks of real notice, not a reminder email the week before the deadline.
Testing Requirements: ISEE or SSAT, and the Grade 10–11 Exception
Every applicant takes either the ISEE or SSAT, registered independently of the Flintridge Prep application itself. The one exception: students applying to grades 10 or 11 may submit a PSAT, SAT, or ACT score in place of the ISEE/SSAT, which matters for families whose child has already sat for one of those exams for other reasons and would rather not add a second test to the calendar.
Every applicant, regardless of grade, also completes the Character Skills Snapshot, a standardized assessment of traits like resilience, empathy, teamwork, self-control, and curiosity. It’s one input among several in a holistic review, not a pass/fail cutoff on its own.
Applying to Flintridge Prep?
The steps themselves aren’t complicated, but the timeline is unforgiving: a transcript request placed too late or a recommendation started the week it’s due can hold up an otherwise strong application. Families who start early, and who understand which components apply to their child’s specific grade, tend to move through the process with far less last-minute scrambling.
