This page is the calendar: what happens when, school by school, and what to do in each month. For how admission works, including entry grades, testing rules, portals, the file, and interviews, read the Los Angeles private-school admissions guide.
The regional framework
LAIS coordinates the finish, not the whole race.
Verified fact: LAIS describes itself as a consortium of more than 60 Los Angeles-area independent schools and says its members follow common decision-notification and response dates. Its searchable directory is the cleanest starting universe, but families should confirm that each particular school and grade follows the published calendar.
Verified fact: For Fall 2027 K–12 admission, LAIS recommends March 12 notification and March 19 replies. Schools may, at their discretion, grant revisit requests to newly admitted families; the association does not promise a common revisit program.
Verified fact: LAIS says each family must follow the individual school’s aid procedure and deadline.
There is no universal application opening, application deadline, age cutoff, interview format, testing requirement, aid platform, late-application right, or enrollment contract. Those remain school-specific.
Entry grades
Choose the grade before you build the calendar.
Which grades are main entry points, and what each school publishes about intake, is covered in the admissions guide. The calendar below assumes the list is already set.
The 2027–28 master calendar
Build backward from the first gate, not the final deadline.
| Window | Verified season activity | Parent-first move |
|---|---|---|
| March–May 2026 | LAIS maintains a regional member directory; individual schools begin publishing or previewing the coming process at different times. | Define the entry grade, maximum weekday commute, support needs, identity or program must-haves, and realistic full-cost ceiling. Drive likely routes at school-hour speed. |
| June–July | Oakwood lists a July 1 application opening. Other schools open later; an inquiry may be required before the portal is visible. | Gather legal names, addresses for both households, prior school names, report cards, testing already on file, and aid documents. Do not ask teachers for recommendations in summer unless a school tells you to. |
| August | Sierra Canyon opens August 1, Crossroads August 3, New Roads August 10, and Campbell Hall August 17. Marlborough’s and other current applications are also live by early September. | Open every intended portal, record the platform and login owner, and copy every checklist item into one family tracker. Book only events that answer a real fit question. |
| September–October | Interviews and tours begin at several schools. Connected-family deadlines start September 30 at Campbell Hall and run through October at Oakwood, Archer, Sierra Canyon, and Milken. | Draft parent responses, let older students write in their own voice, choose a test route only after checking every school, and start aid applications as soon as they open. |
| November 1–20 | Many current-school forms become available after November 1. Interview-protection dates cluster here: Buckley November 9, Archer and Windward November 12, Harvard-Westlake November 13, Campbell Hall November 16, and Brentwood and Oakwood November 20. | Treat a guaranteed-interview or priority date as the working deadline. Send one accurate recommender list, then monitor receipt without coaching the recommendation. |
| December 8–18 | Final application deadlines cluster: Buckley K–5 December 8; Archer December 10; Milken December 11; New Roads December 14; Windward and Sierra Canyon December 15; Crossroads, Campbell Hall, and Buckley Grades 6–12 December 16; Oakwood December 18. | Finish child-authored work before winter break. Download or screenshot each submitted application and confirm that the portal says submitted, not merely started. |
| January 1–20, 2027 | Buckley’s aid priority date is January 1; Chadwick’s application is due January 4; many records and recommendations are due January 8; Harvard-Westlake and Milken files close January 15; Windward testing closes January 19; Campbell Hall new-family aid closes January 20. | Audit every checklist by component. A requested transcript is not a received transcript. Keep current teachers focused on the child’s school year, not on portal anxiety. |
| Late January–February | Student assessments and interviews continue. Sierra Canyon accepts required testing evidence through February 1; Brentwood’s current aid process requires later W-2/1099 documents by February 5 and a complete aid file by February 12. | Close genuine gaps. Do not manufacture extra contact, recommendations, or achievements after the file is complete. |
| March 12–19 | LAIS notification and reply week. | Compare the full contract, aid award, deposit, commute, calendar, support, and child response. Ask factual questions quickly; the common reply window is one week. |
| Late March–August | Enrollment, health, records, transportation, placement, tuition-plan, orientation, and summer-work steps are school-specific. | Close the old school relationship graciously, calendar all new-family obligations, and make the commute plan real before the first day. |
Editorial opinion: A family should aim to be one week early for any gate that controls appointments and three school days early for an online final deadline. That margin is for illness, login trouble, and ordinary family life—not strategic signaling.
School-by-school dates
Thirteen schools, thirteen sets of Fall 2027 dates.
An interview-guarantee or priority date is the working deadline, even when a later final date exists.
| School | Application and file deadlines |
|---|---|
| Harvard-Westlake | November 13 interview guarantee; January 15 admission and aid file |
| Crossroads | November 6 optional early date for new/connected secondary families; December 16 final application; January 8 materials |
| Brentwood School | K November 6; Grades 6–12 November 20 interview guarantee, January 8 final application and materials |
| Marlborough | January 8 application and supporting items |
| Archer | November 12 interview guarantee; December 10 application and Flexible Tuition; January 8 materials |
| Windward | December 15 application; January 8 forms; January 19 final ISEE deadline |
| Campbell Hall | November 16 interview guarantee; December 16 final application; January 8 forms; January 20 new-family aid |
| Buckley | November 9 priority/guaranteed interview; December 8 K–5; December 16 Grades 6–12; January 1 aid priority |
| Oakwood | November 20 priority; December 18 final; January 8 forms |
| New Roads | December 14 application; January 8 materials and aid |
| Milken | December 11 application; January 15 forms and scores |
| Chadwick | January 4 application; grade-specific January activities |
| Sierra Canyon | December 15 application; January 8 supplemental file and aid; February 1 testing evidence |
Portal access takes time
Request portal access weeks before any deadline.
Several schools require an inquiry before the application appears, and Harvard-Westlake and Milken say account setup can take up to two business days. Each school’s system is described in the admissions guide.
Test windows
Book one test date with a retake buffer before the earliest score deadline.
Which schools require, accept, or ignore standardized tests is covered in the admissions guide. These are the Fall 2027 windows that set the calendar.
| School | Window or deadline | Planning consequence |
|---|---|---|
| Harvard-Westlake | Submit one ISEE administration taken August 1, 2026 through January 15, 2027. | Book within the school’s window and name one result. |
| Windward | Final testing deadline January 19, with earlier preferred timing for Grades 8–11. | Do not confuse the preferred date with the final date. |
| Milken | New-family materials and scores are due January 15. | Check what the current school already has before retesting. |
| Sierra Canyon Grades 6–11 | Required testing evidence is due February 1. | School-administered results may already be on file. |
| Archer | At-home writing and math exercises are assigned after the interview. | Leave a quiet slot in the weeks after the interview. |
Editorial opinion: Choose the test route only once the list is stable. For access arrangements, contact the test provider and schools early; do not assume that school accommodations automatically transfer to an admission test.
Records and recommendations
The quiet dependency is your current school’s calendar.
Many current-school forms become available only after November 1, and your current school has its own lead times and holiday blackout dates. Which forms each school wants, and district exceptions, are in the admissions guide.
| Step | Do this | Avoid this |
|---|---|---|
| Before November | Ask the current school for its placement policy, lead time, blackout dates, and whether it sends one common form or portal-specific forms. | Sending forms before schools permit current-year work. |
| Final list | Give the school one accurate destination list with grade, portal, role, and due date. | Adding schools one by one without alerting the registrar. |
| Delegation | Use the teacher or administrator the application specifies; waive access where required. | Choosing the warmest adult when the form requests current math. |
| Monitoring | Check portal status weekly and send one respectful reminder through the current school’s preferred channel. | Repeatedly asking teachers whether the letter is “strong.” |
| Records | Distinguish release authorization, transcript request, report card, prior years, testing on file, and midyear update. | Assuming “transcript requested” means every item arrived. |
Editorial opinion: The best recommender is the required current educator who knows the child’s real classroom work. A parent’s job is to provide time and correct routing—not themes, adjectives, or a script.
Booking interviews
Interview slots open after the application, then fill.
At Brentwood, Archer, Buckley, and Chadwick, submitting the application is what unlocks interviews, tours, or appointments, and Milken’s interview self-scheduling opens only after account processing. The November interview-guarantee dates are the ones that protect a slot. What each format looks like is covered in the admissions guide.
Weekly work blocks
Schedule the work so it does not take over the fall.
Editorial opinion: Protect two weekly work blocks for adults and one short block for an older student from September through January. Do not turn a weekend into an all-day admissions shift. Fatigue makes families generic, irritable, and less able to notice fit. The component-by-component inventory is in the admissions guide.
Decision week and enrollment
A seven-day reply window rewards preparation, not panic.
Verified fact: LAIS’s Fall 2027 window runs from Friday, March 12 after 5 p.m. to Friday, March 19 at noon. Schools may allow admitted-family revisits at their discretion.
Before March, build a decision sheet with the same rows for every school: signed-contract deadline, nonrefundable deposit, net tuition, what aid covers, transportation, start and end times, aftercare, athletics or arts return time, learning support, calendar conflicts, and the child’s own observations. Leave the “admitted?” column blank until decisions arrive.
- Read the full enrollment agreement and aid award before clicking accept. Record refund and withdrawal language.
- Ask only unresolved factual questions. If a revisit is needed, request it immediately and understand that it is discretionary.
- Re-run the commute at the actual morning and afternoon times, including the late bus or activity pickup.
- Let the child speak without making them responsible for the family budget or adult status anxiety.
- Accept one place by its deadline, release others promptly, and retain confirmations.
After enrollment, the project changes. Request final records, complete health and emergency forms, choose the tuition plan, confirm transportation, ask about placement or summer work, calendar new-family events, and close the current school relationship with care.
The best Los Angeles calendar is also a family boundary.
The durable calendar works backward from each school’s first appointment gate, not its final deadline. Most of the season is decided in November, when interview guarantees fall, and in the single March week when replies are due.
Our strongest opinion is that admissions should remain an adult logistics project surrounding a child, not a child identity project run by adults. Older students should own their voice. Younger children should meet kind adults and do ordinary age-appropriate things. No result is a verdict on a child’s promise.
We are highly confident in the common March calendar and the school-specific facts cited here as of September 2, 2026. We are not confident in any claim about unwritten preferences, future seat counts, or personal odds—and we do not make those claims.
