ACT to SAT Conversion (Official Concordance)

An ACT composite of 34 compares with an SAT total of 1490 to 1520, and the single value the official table lists is 1500. A 33 compares with 1450 to 1480, with 1460 as its single value. One step up, a 35 matches 1530 to 1560 (1540) and a 36 matches 1570 to 1600 (1590). Each composite from 16 to 36 also has its own score page with its percentile.

A 32 compares with 1420 to 1440, with 1430 as the single value. A 30 compares with 1360 to 1380, with 1370 as its single value, and the 31 between them with 1390 to 1410 (1400). Use the table above to find any composite from 9 to 36.

Find the SAT range that holds your total. A 1500 sits in 1490 to 1520, so it compares with a 34; a 1200 sits in 1200 to 1220, a 25; a 1050 sits in 1030 to 1050, a 20. Switch the converter above to SAT to ACT and type your total for the exact row.

Yes. The table comes from the 2018 concordance study published jointly by ACT and the College Board, the one both test makers and colleges use. ACT says it is not revised every year, and the digital SAT kept the same 400 to 1600 scale, so the 2018 tables still apply.

No. The concordance says which scores mean about the same to colleges; it does not predict your score on a test you have not taken. The two tests reward different skills (the ACT has an optional Science section and a faster pace), so students who take both often land a few points apart. Take a practice test of each if you are choosing between them.

Convert both into one scale with the table and send the higher one, unless a college asks for all scores. If the two match, send the one that sits higher in that college's middle 50% range, which colleges publish in their common data set.

The 2018 study also published ACT Math to SAT Math and ACT English plus Reading to SAT Reading and Writing tables, but colleges compare composites and totals. This page keeps the composite and total table; the SAT and ACT calculators show your section scores and percentiles.
