How to Get Into Trinity School NYC: Acceptance Rate, Fall 2027 Deadlines, Tuition and Aid
By Rona Aydin
Does Trinity School publish an acceptance rate?
No. Trinity does not publish applicant or admit counts on its admissions pages for Kindergarten to Grade 4 or for Grades 5 to 12, so any acceptance rate quoted for Trinity is an outside estimate (Trinity Admissions K-4; Trinity Admissions 5-12). What Trinity does say is that Grade 9 is its “primary entry point” in the upper grades, where it welcomes “a vibrant cohort of approximately 60 new students,” and that its current Kindergarten includes students from “nearly 40 different school programs.”
Trinity is a coeducational K-12 day school at 139 West 91st Street on the Upper West Side of Manhattan. Its home page lists 1,040 students and a 13:1 student-teacher ratio, without a year (Trinity School). It was founded in 1709 as a charity school at Trinity Church; Trinity says it “is no longer sponsored by a specific religious body” and lists membership in the National Association of Episcopal Schools (History of Trinity School).
Which grades can apply to Trinity for fall 2027?
| Grade | Status for fall 2027 | What Trinity says |
|---|---|---|
| Kindergarten | Entry point; application closed October 16, 2026 | “Our traditional entry points are Kindergarten and grade 9” |
| Grades 1 to 4 | Attrition only | Spaces “are available only through attrition” |
| Grades 5 to 7 | Attrition only | Enrollment “is contingent upon availability through student attrition” |
| Grade 8 | No applications | Trinity does “not accept applications or offer entry for Grades 8 and 12” |
| Grade 9 | Entry point; application due November 15, 2026 | Approximately 60 new students |
| Grades 10 and 11 | Attrition only | Same attrition rule as Grades 5 to 7 |
| Grade 12 | No applications | Same rule as Grade 8 |
For the non-entry grades, Trinity says “we typically do not know if these openings will exist until later in the school year,” so those applications follow a separate timeline. In our view, a family aiming for Trinity should plan around Kindergarten or Grade 9 and treat any other grade as a possibility rather than a plan.
What are the Trinity deadlines for fall 2027?
Trinity publishes separate calendars for Kindergarten and Grade 9 (Trinity Admissions K-4; Trinity Admissions 5-12). Its notification and reply dates match the shared calendar of the Independent Schools Admissions Association of Greater New York (ISAAGNY Notification and Reply Dates).
| Milestone | Kindergarten | Grade 9 |
|---|---|---|
| Application | Closed October 16, 2026 at 5:00 PM | Due November 15, 2026 |
| Files complete | January 8, 2027 | January 8, 2027 |
| Financial aid application (new families) | January 8, 2027 | January 8, 2027 |
| Decisions released | February 4, 2027, no earlier than 10:00 AM | February 19, 2027 |
| Parent reply deadline | February 11, 2027, by 12:00 PM | March 11, 2027, by 12:00 PM |
The Grade 9 application is the live deadline. Trinity asks families to submit the initial application and schedule the campus visit through the portal by Sunday, November 15, 2026; after that date, “appointments will be subject to our remaining availability” (Trinity Admissions 5-12). The $75 application fee “is automatically waived for any family applying for financial aid.”
What does the Trinity application include?
Trinity hosts all Grade 9 applicants and their parents or guardians for a campus visit with four parts: a one-on-one conversation with an admissions officer, a collaborative group activity, a short writing exercise and a campus tour led by current students (Trinity Admissions 5-12). The rest of the Grade 9 file is due January 8, 2027:
- Recommendations from a math teacher, an English teacher and a guidance counselor or principal.
- Fall 2026 semester grades and final school transcripts for 2024-2025 and 2025-2026.
- A parent or guardian statement and the student essays.
- ISEE or SSAT results, “taken between August and December of the application year.”
- The financial aid application, if the family is applying for aid.
For Kindergarten, Trinity says a complete file consists of a school tour, an interview for both parent and child, a classroom observation at the child’s school or on a Saturday at Trinity, and a school report; the observation is waived for families who apply from far away and cannot attend (Trinity Admissions K-4). The Lower School testing step applies to Grades 2 to 4, which take the ISEE Primary through ERB. Trinity also says it “cares deeply about siblings and legacies” and is “strongly committed to welcoming many new families every year.” Our ISEE preparation guide covers the test.
What does Trinity cost, and how does financial aid work?
Trinity’s tuition page lists tuition of $71,500 in an item dated August 29, 2025, and does not state which school year that figure covers. Trinity calls its tuition “largely all-inclusive”, covering items such as Lower School lunch and snacks, local field trips and interscholastic team uniforms and equipment (Trinity Tuition, Fees and Financial Aid).
| Item | Figure | Year or note |
|---|---|---|
| Tuition | $71,500 | Dated August 29, 2025; school year not stated |
| Students receiving financial aid | Almost 20% | All grades, current |
| Average financial aid award | $53,905 | 2026-27 |
| Applicants requesting financial aid | 30.6% | 2026-27 |
| Award range | A few thousand dollars to nearly full tuition | Current |
| Aid application deadline, new families | January 8, 2027 | For 2027-28 |
| Aid application deadline, current families | December 16, 2026 | For 2027-28 |
Aid at Trinity is need-based. The program “currently assists almost 20% of our students across all grades,” and Trinity states that “All families contribute something toward the cost” of a Trinity education. We found no mention of merit scholarships on the tuition page. In our view, families should apply for aid by January 8, 2027 alongside the admission file, and should not assume a full-tuition award, since Trinity describes its top awards as nearly full tuition.
Where do Trinity graduates go to college?
Trinity publishes its college enrollment for the Classes of 2021 to 2025 as an interactive map on its College Counseling site, without counts that we could read, and it had posted no Class of 2026 list when we checked on November 4, 2026 (Trinity Matriculation). We therefore print no Trinity matriculation counts or rates. For comparison, Horace Mann publishes three-year counts by college, covered in our Horace Mann admissions guide. In our view, families should ask the Trinity college counseling office directly for the numbers behind the map, and should read them against current Ivy League acceptance rates.
How should families plan a Trinity application now?
In the view of Oriel Admissions, a Grade 9 family starting now should finish the application and book the campus visit before November 15, 2026, take the ISEE or SSAT by December, and use the remaining weeks for the essays and recommendations due January 8, 2027. The writing exercise and group activity reward students who are comfortable thinking aloud with peers, which is worth practicing before the visit. Families often apply to several schools on the shared New York calendar; our guides to Dalton, Collegiate and the most selective NYC private schools cover the main alternatives.
