Convert between SAT and ACT with the official concordance — and see your percentile
| SAT | ACT | Percentile | Band |
|---|
Every college accepts both the SAT and ACT with genuine indifference — but merit-aid grids, admissions bands and your own prep strategy all need the two scales reconciled, which is what the official College Board/ACT concordance table (embedded here) does. This converter runs both directions, attaches percentiles, and answers the strategic question underneath: which test should this particular student prep for?
| SAT / ACT | What it opens |
|---|---|
| 1530+ / 35+ | Competitive at every school; NMSQT-adjacent; automatic full-tuition grids at a set of flagships |
| 1400–1520 / 32–34 | Top-tier admissions plausible; large automatic merit at most publics |
| 1300–1390 / 28–31 | The merit sweet spot — flagship admits with published scholarship tiers (the Scholarship tool's grids live here) |
| 1100–1290 / 22–27 | Solid four-year admits; merit at schools a tier down |
| Below 1100 / 22 | Test-optional strategy usually maximizes outcomes — submit nothing and let GPA carry |
Most colleges remain test-optional, but "optional" is strategic, not decorative: submit when your converted score sits at or above the school's published middle-50%, withhold when below. Merit grids are the exception — many automatic scholarships still require scores, which keeps testing worthwhile even for test-optional applications.
It's the official concordance — the same table admissions offices use — but concordance is statistical alignment, not identity: a 1360 and a 30 are 'comparable,' not interchangeable percentile-for-percentile at every point. For merit grids, the school's own published table (some run slightly generous conversions) is final.
No — every US college accepts both equally, officially and in practice. Regional patterns (ACT in the Midwest/South, SAT on the coasts) reflect state testing contracts, not preference. Take the one you score higher on, full stop.
Relative to purpose: the national ACT average is ~19-20 (SAT ~1030); flagship admits cluster 1200-1350/25-30; the merit grids pay from ~1300/28 up; Ivy-class middle-50%s start around 1500/34. 'Good' = at or above the middle-50% of YOUR list.
Meaningful, bounded gains: structured prep (60-100 hours over 2-3 months) averages 90-150 SAT points / 2-4 ACT points, with the biggest jumps from the lowest starting familiarity. Free resources (Khan Academy's official SAT partnership) rival paid courses in measured outcomes; the variable is the hours, not the price.
Most colleges superscore the SAT (best section scores across dates) and a growing share superscore the ACT. Plan for it: 2-3 sittings, targeted section prep between them. Score-choice (sending only chosen dates) is also widely allowed — check each school's policy page.
Usually yes, once: the score is an OPTION you can decline to use for admissions but often can't decline for merit grids and honors colleges, which still require it. One prepped sitting preserves every option; skipping testing forecloses the scholarship tables.

Convert with the official table, submit strategically against the middle-50%, and let the two-diagnostic experiment pick your test. The score is a key that opens merit grids — cut it on whichever blank fits your hand.
