Official Concordance Table (2018)
The table below shows the official relationship between SAT Total Scores (400-1600) and ACT Composite Scores (1-36). This concordance was jointly developed by the College Board and ACT, Inc. and is the standard used by admissions offices nationwide.
| SAT Score Range | ACT Score | Competitiveness |
|---|---|---|
| 1570-1600 | 36 | Perfect |
| 1530-1560 | 35 | Elite |
| 1490-1520 | 34 | Elite |
| 1450-1480 | 33 | High |
| 1420-1440 | 32 | High |
| 1390-1410 | 31 | Very Good |
| 1360-1380 | 30 | Very Good |
| 1330-1350 | 29 | Good |
| 1300-1320 | 28 | Good |
| 1260-1290 | 27 | Above Average |
| 1230-1250 | 26 | Above Average |
| 1200-1220 | 25 | Above Average |
| 1160-1190 | 24 | Average |
| 1130-1150 | 23 | Average |
| 1100-1120 | 22 | Average |
Key Differences Between SAT and ACT
While both tests measure college readiness, they differ in important ways. Understanding these differences can help you decide which test to focus on:
SAT Characteristics
- Scored 400-1600
- Fully digital and adaptive
- 2 hours 14 minutes
- More time per question
- Emphasis on algebra and data analysis
- Shorter reading passages (1 question each)
- Built-in Desmos calculator for all math
ACT Characteristics
- Scored 1-36
- Transitioning to digital format
- 2 hours 55 minutes (without writing)
- Less time per question, faster pace
- Broader math coverage (more geometry/trig)
- Optional Science section
- Bring your own calculator
How to Decide Which Score to Send
If you have taken both tests, follow this process to determine which score gives you a stronger application:
- Convert both scores using the concordance table above. For example, if you scored a 1380 SAT and a 29 ACT, convert both to the same scale.
- Compare the equivalents: A 1380 SAT converts to approximately a 30 ACT. Since you scored a 29 on the actual ACT, your SAT score is relatively stronger.
- Submit the stronger score. In this example, you would submit the 1380 SAT because it is equivalent to a higher ACT score than what you actually achieved.
Colleges will not view your application differently based on which test you submit. Both are treated equally in the admissions process.
When to Consider Taking the Other Test
Some students perform significantly better on one test over the other due to differences in format and pacing. Consider taking the other test if:
- Your scores do not match the concordance: If your SAT converts to a 33 ACT but you only scored a 29 on the actual ACT (or vice versa), the test formats may suit you differently.
- You struggle with time pressure: The SAT gives more time per question. If you frequently run out of time on the ACT, the SAT may be a better fit.
- You excel in science reading: The ACT Science section is essentially a data interpretation and reading test. Students with strong chart-reading skills often score well here, boosting their composite.
- You prefer deeper math: The SAT math section covers fewer topics in more depth (heavy on algebra). The ACT covers more topics including additional geometry and trigonometry.
Merit Scholarship Considerations
Many merit scholarships have specific score thresholds that are listed in terms of one test or the other. Common examples:
- A scholarship might require "1350 SAT or 29 ACT." Using the concordance, a 1350 actually converts to a 29, so these cutoffs are equivalent.
- However, some scholarships round differently. Always check both the SAT and ACT thresholds and submit whichever score meets or exceeds the requirement.
- If a scholarship only lists one test's requirement, use the concordance table to check if your score on the other test qualifies.
Frequently Asked Questions
Are SAT and ACT scores directly comparable?
Not directly, since the SAT uses a 400-1600 scale and the ACT uses a 1-36 scale. However, the official concordance tables released by the College Board and ACT, Inc. provide a standardized way to compare equivalent scores across both tests.
Should I submit my SAT or ACT score to colleges?
Submit whichever score is relatively higher when converted using the concordance table. For example, if your SAT converts to a 32 ACT equivalent but you only scored a 30 on the actual ACT, submit the SAT. Colleges do not prefer one test over the other.
Do colleges accept both SAT and ACT equally?
Yes. All US colleges and universities that require or accept standardized tests treat SAT and ACT scores equally. Admissions officers use concordance tables to compare applicants who submitted different tests.
