SSAT vs. ISEE: A Seattle Parent's Timeline for Private School Admissions Testing
If you are the parent sitting at the kitchen table with a private school application open, trying to decide between the SSAT and the ISEE, you are in good company. Every fall, Seattle parents face the same puzzle: two tests, two registration systems, and little guidance on which one matters for the schools on their list.
You already know your child better than any test does. Here is a clear comparison and a realistic timeline built around the 2026 to 2027 testing calendar, so you can make the call with confidence.
What is the difference between the SSAT and the ISEE?
Both tests are standardized admissions tests used by independent schools, and both send schools an unscored writing sample. The biggest differences are how each test is scheduled and how often your child can take it.
The SSAT runs on six fixed national Saturdays, with At Home and Flex options for families who need more flexibility. The ISEE runs in three testing seasons (fall, winter, and spring/summer), and a student can test once per season. The ISEE is now provided by E3n, the nonprofit formed when the Educational Records Bureau and the Enrollment Management Association merged.
Which Seattle-area independent schools require the SSAT or the ISEE?
Many Seattle independent schools accept either test, but requirements vary by grade level and can change from year to year. Confirm the current requirement on each target school's admissions page before you register. When a school accepts both, choose the format that fits your child best.

When should we test for fall 2027 enrollment?
For the 2026 to 2027 cycle, the remaining SSAT paper dates are November 14 and December 12, 2026, followed by January 9, January 30, and March 13, 2027. The ISEE fall season runs through November, and its winter season runs December through March.
Here is what that means if your family is aiming for a fall 2027 start:
Right now: Confirm which test each target school requires. If your child will test with accommodations, apply before you register for anything. Once the file is complete, ISEE review typically takes one to two weeks.
October: Register for a November or December date. For the November 14 SSAT, regular registration closes October 24 and the accommodated testing deadline is October 31. Elementary Level students can take the paper SSAT on November 14 or December 12 this fall.
November and December: Your child takes a first attempt. This score works best as a baseline that shows where to focus if a retake makes sense.
January: Use this window for a retake if needed, and check each school's score deadline carefully. Lakeside, for example, needs test scores by January 28, 2027.
How do we decide which test fits our child?
You are the best judge of how your child handles pressure, so start with their temperament and your family calendar. The SSAT's fixed Saturdays give you set dates to plan around, and several dates fall within a single season, so a quick retake is possible. The ISEE offers testing at many member schools, which some students find calmer, but a retake means waiting for the next season.
Setting matters too. Both tests offer at-home options, and some children do their best work in a familiar room. A short practice test in each format usually confirms what you already suspect.
What does calm, focused test prep look like?
The best fall prep fits into a school year your family is already adjusting to. At Liddane Tutoring, SSAT and ISEE preparation is built around your child's test date and target schools, with three levels of support:
Triage (1–3 sessions): Test structure, timing, test-taking strategies, and stress reduction, ideal for a brief refresher before test day.
Target (4–5 sessions): The Triage foundation plus focused time on one identified area of improvement.
Deeper Dive (6–8 sessions, recommended for most students): Everything above, plus time to review the test as a whole.
For families of students with ADHD or other learning differences, we can also walk you through the accommodations process so every deadline stays on track.
Frequently asked questions
-
Yes. Most families still choose one based on what their target schools accept, since preparing well for a single test is usually more effective than splitting focus.
-
Three months of lead time before a target date is a reasonable guideline for most students. Families aiming for December or January should begin reviewing structure and strategy now.
-
No. ISEE score reports do not flag accommodations, and approvals are valid for 24 months.
