The College Board/ACT concordance — what’s real and what’s guesswork
Because colleges historically used different cutoffs for SAT vs. ACT, the two testing organizations jointly produce a “concordance table” mapping ACT composite scores (1–36) to SAT total scores (400–1600). The current version was last fully updated in 2018, with minor digital-SAT adjustments in 2023. Key conversion points:
| ACT composite | SAT total | Percentile |
|---|---|---|
| 36 | 1570–1600 | 99+ |
| 34 | 1500–1530 | 99 |
| 32 | 1430–1460 | 97 |
| 30 | 1360–1390 | 93 |
| 28 | 1300–1330 | 88 |
| 26 | 1240–1270 | 82 |
| 24 | 1170–1210 | 73 |
| 22 | 1110–1140 | 62 |
| 20 | 1030–1060 | 49 |
| 18 | 960–990 | 36 |
Which test suits you better
There’s real variance in which test favors individual test-takers. Rules of thumb:
- Take the SAT if: you’re a stronger reader than math student, you prefer fewer questions with more time per question, or you’re applying to Ivies / Stanford (traditional strongholds of SAT).
- Take the ACT if: you work fast, you’re strong in science (the ACT has a dedicated science section, SAT doesn’t), or your target colleges are in the Midwest / South (ACT territory).
- Try both practice tests: spend 4 hours on a full official SAT practice test, 4 hours on a full ACT. Whichever yields higher percentile is your test.
What colleges actually see
Most 4-year colleges accept either test without preference (explicit since the Common App made the “test choice” ambiguous). Internal admissions committees typically convert to a single scale using the concordance table. A 1430 SAT and a 32 ACT are treated identically on a Common App review.
Exception: some scholarship programs have test-specific thresholds. Florida Bright Futures requires specific SAT or ACT scores (not interchangeable). Some ROTC scholarships are ACT-only.
Super-scoring across tests
Some colleges will super-score within a single test (your highest individual sections across multiple sittings). A handful will super-score acrosstests — your best SAT sections + best ACT sections, converted to one scale. This is rare but worth checking each school’s policy; Vanderbilt and Duke have historically been open to this.
Writing / Essay sections
The SAT eliminated its optional essay in 2021. The ACT optional writing test is still offered. Most colleges don’t require or consider it as of 2025 — only a handful (Stanford dropped the requirement 2024, Caltech, UC system) still look at writing scores. Check your target schools’ current policy before paying the extra $25 for ACT writing.
Section-by-section conversion detail
The overall concordance mask is cleaner than the section-level conversions. Rough section-equivalents:
- SAT Reading/Writing (200-800) → ACT English (1-36) + ACT Reading (1-36) averaged: An SAT R/W of 700 is roughly equivalent to an ACT English+Reading average of 32.
- SAT Math (200-800) → ACT Math (1-36): An SAT Math of 730 is roughly equivalent to ACT Math 32-33.
- ACT Science (1-36): No direct SAT equivalent. Treated as its own data point for STEM-heavy schools.
Students consistently ~5 scaled-score points higher on ACT English than on SAT Reading/Writing often have a test-type mismatch — the ACT rewards fast readers who skim efficiently, while the SAT rewards careful close-reading. A 33 ACT English + 25 ACT Math may convert to a 1450 on the concordance, but colleges see the sectional disparity and dig in.
Retake strategy by starting score
Currently 1100 SAT / 22 ACT:40-80 hours of prep can realistically push to 1250 / 26. That’s the difference between community college transfer and competitive admission to most regional flagships. Worth the investment.
Currently 1300 SAT / 28 ACT:60-100 hours of prep can push to 1400 / 31. That’s the difference between most state flagships and top-50 schools. Good ROI on prep.
Currently 1450 SAT / 33 ACT: 80-160 hours can push to 1520 / 34-35. Diminishing returns per hour, but the score gap opens top-20 schools. Worth it if reach schools are the target.
Currently 1520+ / 35+:Additional prep often doesn’t help and can hurt (test fatigue, overthinking). Don’t retake unless you’re specifically chasing a named scholarship threshold.
Test cost breakdown 2025-26
- SAT registration: $68 (with $43 late fee if you miss deadline).
- ACT registration: $68 (without writing), $93 (with writing).
- Score reporting beyond the free 4 schools: $14/report each.
- Fee waivers: Free for Pell-eligible students (2 SAT + 2 ACT, plus unlimited score reports, plus CSS Profile waivers). Apply through school counselor or directly via testing body.
Test-optional vs. test-required 2025-26
The test-optional wave peaked 2020-2022. Several schools have reinstated requirements: MIT (2024), Dartmouth (2024), Yale (2024), Brown (2024), Harvard (2025), Caltech, Georgetown, UF, and all UC/CSU campuses. UT Austin is test-required. Most of the Ivy League is now test-required or test-recommended.
Test-optional schools (~50% of US 4-years) will consider your score if submitted. Rule: submit if your composite is above the school’s 25th percentile. Don’t submit if below. For holistic-admission schools, your score below the 25th percentile is a negative signal; withholding is neutral.
Common questions
If I take both, should I send both?Send whichever looks stronger relative to that school’s published medians. Sending both isn’t harmful but is redundant — colleges use the higher-convertibility score.
Does the digital SAT make conversion different? College Board says no — the 1600 scale is stable. But anecdotally, some students score 30-60 points higher on digital than paper due to adaptive format (the second module adjusts difficulty based on first module).
Can I take the test in 11th grade vs. 12th grade? Most students take their first SAT/ACT spring of junior year (March/April/May), retake summer or early fall of senior year, and submit scores by November for early applications. Sophomore testing is fine for motivated students but retakes are more consequential late-junior-year than early.
What’s the maximum number of times I can test?No hard cap, but diminishing returns. Colleges see all scores if you select “Score Choice” off; most now super-score the best sections. Plan to take each test at most 2-3 times.
Are SAT subject tests still a thing? No — discontinued in 2021. AP scores have largely replaced them for demonstrating subject mastery.
Do homeschooled students take the same tests? Yes. Some homeschool students need SAT/ACT scores for college applications even at test-optional schools because they lack a traditional transcript.
Can my ACT writing score hurt me? If you score below 6/12 on ACT writing at a school that considers it, yes. If you score average or above, neutral. Research your target schools — most now ignore it.
