Key Takeaways
- Stanford's admitted-student middle-50 SAT range is 1510 to 1570 and the middle-50 ACT range is 34 to 35, per the most recent Common Data Set.
- The average admitted student scores approximately 1540 on the SAT and 34 to 35 on the ACT, both inside the top 1 percent of test takers nationally.
- Stanford has reinstated the SAT or ACT requirement beginning with the Class of 2030 (fall 2025 applications). Testing is no longer optional.
- Stanford's overall acceptance rate is roughly 3.6 percent, the lowest among any U.S. research university, so strong scores are necessary but nowhere close to sufficient.
- Stanford superscores both the SAT and ACT, using your highest section results across all sittings.
What SAT or ACT Score Do You Need for Stanford?
Stanford does not publish a minimum SAT or ACT score, and neither test has a formal cutoff. What Stanford does publish in its annual Common Data Set are the 25th and 75th percentile scores of enrolled first-year students. For the most recent enrolled class those figures are:
| Score type |
25th percentile |
75th percentile |
Estimated average |
| SAT total | 1510 | 1570 | 1540 |
| ACT composite | 34 | 35 | 34.5 |
Half of enrolled Stanford first-years scored inside those bands. A quarter scored higher and a quarter scored lower. In practical terms: aim for roughly 1540 on the SAT or 35 on the ACT to land at Stanford's median. A 1510 or 34 keeps you in the competitive range; a 1570 or 36 puts your score at or above most admits. Source: Stanford Admission.
Stanford SAT Score Breakdown by Section
Within the SAT, Stanford's Math section compresses harder than Reading and Writing. Most admits arrive with a near-perfect Math score:
| SAT section |
25th percentile |
75th percentile |
| Reading and Writing (EBRW) | 740 | 780 |
| Math | 770 | 800 |
A couple of signals to read here. The SAT Math 75th percentile is a perfect 800, meaning at least a quarter of Stanford's entering class earned 800 on Math. The 25th percentile sits at 770, only one or two missed questions from a perfect score. EBRW runs in a 740 to 780 band, slightly wider than Math but still at the top of the scale.
For STEM-heavy intended majors at Stanford, realistically target 790 or higher on Math. Stanford engineering and computer science admits rarely arrive below that threshold. For the section-specific SAT preparation breakdown, see our SAT Math practice guide.
Stanford ACT Score Breakdown by Section
Stanford publishes only the composite ACT middle-50 range, not per-section cutoffs. That said, admitted student profiles consistently show all four sections clustered within one or two points of the composite. Based on the 34 to 35 range, admitted students typically post:
- English: 34 to 36
- Math: 33 to 36 (slightly wider, mirroring the SAT pattern)
- Reading: 34 to 36
- Science: 33 to 36
Translating to the SAT scale via the official concordance, an ACT 34 maps to roughly a 1510 SAT and an ACT 36 maps to a 1570 or higher. A 35 composite is the cleanest match for Stanford's SAT median.

SAT vs ACT for Stanford: Does It Matter Which You Take?
No. Stanford accepts both tests equally and does not apply any conversion penalty or adjustment. Admissions readers see your score placed on a common percentile band, regardless of which test produced it. The practical question is not which test Stanford prefers, but which test you score higher on personally.
A quick heuristic:
- Strong at fast, straightforward questions under time pressure: the ACT tends to favor you.
- Strong at subtle, multi-step reasoning with a bit more time per item: the SAT tends to favor you.
- Unsure: take one official practice test of each back-to-back, convert both to percentile, and pick the higher.
For a deeper test-by-test comparison read our SAT vs ACT guide. Stanford will also accept both tests from the same applicant, reading both without penalty.
Stanford Testing Policy in 2026
Stanford went test-optional in spring 2020 during the pandemic. That policy lasted five admissions cycles. In June 2024, Stanford announced the reinstatement of standardized testing, effective for applicants to the Class of 2030 (fall 2025 applications, fall 2026 entry). The requirement is in force for the current and all future cycles. Source: Stanford Report.
What that means for you right now:
- All first-year applicants to Stanford must submit either SAT or ACT scores.
- Self-reported scores are accepted on the Common App and Coalition. Official score reports are required only after admission.
- Stanford superscores both tests. For the SAT, it considers your highest EBRW and Math across all sittings. For the ACT, it considers your highest section scores and will use a calculated superscore if you choose to report it.
- Stanford does not require or recommend SAT Subject Tests (discontinued in 2021) or SAT Essay (discontinued in 2021).
- Stanford will continue to evaluate applications in context, meaning a test score is interpreted alongside school profile, coursework, and personal background rather than as a standalone number.
During the five test-optional cycles, Stanford reported that roughly half of enrolled students had submitted SAT scores and 19 percent had submitted ACT scores. Under the new requirement, effectively 100 percent of admits will submit a score, which will likely tighten the reported middle-50 range further upward over the next two class reports.
How Much a Top Score Actually Helps
Stanford's acceptance rate sits at approximately 3.6 percent, the lowest of any U.S. research university. At that selectivity, no single factor buys admission. A strong test score gets your file read carefully. It does not get you in. Here is the honest read of how scores interact with the rest of your application:
- Below the 25th percentile (SAT under 1510 or ACT under 34). Your score becomes a constraint. You now compete primarily on other dimensions: hooked status, exceptional extracurricular accomplishment, a compelling personal narrative, or a specific institutional priority.
- Inside the middle 50 (1510 to 1570 or 34 to 35). Your score is neutral. Readers move past it quickly and the rest of your file carries the decision.
- At or above the 75th percentile (1570+ or 36). Your score adds a small positive signal, but the marginal benefit is smaller than most applicants assume. Above a 1540, each additional 20 points buys less than the gain from a tighter essay or a deeper extracurricular narrative.
Stanford is famous for taking students with perfect academic profiles and rejecting them, and admitting students with slightly lower scores but unusual depth. If you already sit inside the middle 50, your prep hours are usually better spent refining essays or extracurricular narratives than chasing another 30 SAT points.
What Stanford Weighs Beyond Test Scores
Stanford is a whole-file read, described by the admissions office as a "holistic and comprehensive review." Every admitted student is evaluated across academic, personal, and extracurricular dimensions. Roughly in order of weight:
- Academic record. Transcript, course rigor (AP, IB, honors, dual-enrollment), GPA in context of your school profile. Stanford admits almost exclusively from the top 10 percent of high school classes.
- Standardized test scores. SAT or ACT, now required again.
- Essays. The Common App personal statement plus Stanford's three short-answer questions (50 words each) and three short essays (100 to 250 words each). The Stanford supplements are distinctive and carry real weight.
- Letters of recommendation. Two teachers plus one counselor, ideally from junior-year core classes.
- Extracurriculars. Depth over breadth. Stanford looks for intellectual vitality and sustained commitment.
- Institutional and demographic factors. First-generation status, regional representation, recruited athletics, and specific institutional priorities. Stanford announced in 2025 that it would continue legacy admissions consideration.
A 1540 applicant with an unusual extracurricular narrative regularly outperforms a 1600 applicant with a generic profile. The Stanford short-answer section, in particular, rewards specificity and personality; generic answers read as an instant weakness.
A Realistic Prep Timeline for Stanford-Level Scores
If you are starting from a 1400 SAT or 30 ACT and Stanford is a serious target, most admitted students follow a version of this timeline:
- Sophomore spring to junior summer. Pick your test. Take one full official practice test of each (Bluebook for SAT, ACT's official practice for ACT). Commit to the one where you score higher in percentile.
- Junior fall. Begin structured prep. Aim for two or three hours per week of focused practice plus one full timed test every two weeks.
- Junior spring. Take the first official sitting. Use your score report to redirect prep to whichever section is weakest.
- Summer before senior year. Intensive prep window. Target one full practice test per week with precision review of every miss.
- Fall senior year. Second and final sitting. Stanford superscores, so a retake can lift your composite even if one section dips slightly.
The single highest-leverage habit at this score range is precision review: every missed question gets categorized by error type and its pattern fixed before moving on. Volume drilling without that review plateaus fast. For an adaptive study plan that tracks your scaled score and weakest topics across sections, try the Larry Learns SAT platform.
Stanford Versus Harvard and the Ivy League
Stanford's published score range sits slightly below Harvard's at the bottom but matches at the top. Practical implication: if you are competitive for Stanford, you are competitive for the Ivy-plus tier as a whole.

Frequently Asked Questions About Stanford SAT and ACT Scores
What is the average SAT score for Stanford?
Approximately 1540, based on Stanford's Common Data Set. The middle-50 range of admitted students is 1510 to 1570. That average places Stanford admits in the top 1 percent of all SAT takers nationally.
What is the average ACT score for Stanford?
Approximately 34 to 35, with a middle-50 composite range of 34 to 35. That range places Stanford admits inside the top 1 percent of ACT takers.
What are Stanford's SAT requirements?
Stanford now requires either the SAT or the ACT for all first-year applicants, effective with the Class of 2030 (fall 2025 applications). There is no formal minimum score, but the admitted-student middle-50 range is 1510 to 1570 SAT.
What are Stanford's ACT requirements?
Stanford requires either the SAT or ACT, not both. There is no minimum ACT score. Admitted students' middle-50 range is 34 to 35 composite.
Does Stanford require the SAT or ACT?
Yes. Stanford reinstated the standardized testing requirement beginning with the Class of 2030 (fall 2025 applications, fall 2026 entry). Every first-year applicant now submits either an SAT or ACT score.
Does Stanford prefer the SAT or the ACT?
Neither. Stanford accepts both tests equally and does not apply any conversion or adjustment. Take whichever test you score higher on relative to percentile.
Does Stanford superscore?
Yes. Stanford superscores both the SAT (highest EBRW plus highest Math across sittings) and the ACT (highest individual section scores). Multiple sittings can only help your reported composite.
Can I get into Stanford with a 1500 SAT?
It is possible but difficult. A 1500 is just below Stanford's 25th percentile of 1510. Applicants at that score who get in typically have an exceptional hook: national-level extracurricular accomplishment, recruited athletics, first-generation status, or a compelling personal narrative.
What SAT score guarantees admission to Stanford?
No SAT score guarantees admission. Stanford's 3.6 percent acceptance rate means even perfect 1600 scorers are rejected regularly. A top score signals academic readiness; the rest of your file determines the decision.
How does Stanford compare to Harvard on scores?
Very similar. Harvard's middle-50 is 1500 to 1580 compared to Stanford's 1510 to 1570. Either school's median lands near 1540 to 1550. Any score competitive for one is competitive for the other. See our Harvard guide for the detailed comparison.
How many times should I take the SAT or ACT for Stanford?
Most Stanford admits take their test of choice twice. A third sitting is common and does not hurt because Stanford superscores. More than three sittings rarely adds value.
