Introduction
The SAT and ACT have long been central to U.S. college admissions, though their role has shifted significantly in recent years as many universities have adopted test-optional or test-flexible policies. Understanding what these tests measure, how they differ, and how current policies affect your application strategy can help you make an informed decision about whether and how to prepare for them.
What Is the SAT?
The SAT is a standardized test historically focused on evidence-based reading and writing and math, designed to assess skills relevant to college readiness. The exact format, scoring scale, and content of the SAT have changed over time, including a shift to a digital format in recent years, so students should review the current official format on the College Board’s website rather than relying on older descriptions.
What Is the ACT?
The ACT is a standardized test that has historically included sections in English, math, reading, and science, with an optional writing section at many points in its history. Like the SAT, the ACT’s format and policies can be updated over time, so students should check the current official format on the ACT’s official website.
Key Differences Between the SAT and ACT
While both tests are widely accepted at U.S. universities that require or accept standardized testing, some general differences have historically included:
- The ACT has traditionally included a dedicated science reasoning section, while the SAT integrates data interpretation across sections rather than having a standalone science section
- Scoring scales differ — the SAT is scored differently than the ACT — making direct comparisons require a conversion, which both testing organizations and many university websites provide
- Some students report a preference for one test’s pacing or question style over the other
Because formats and content are periodically updated, students should consult current official practice materials from both testing organizations to determine which test format suits them better, if choosing between the two.
Test-Optional and Test-Flexible Policies
In recent years, a significant number of U.S. universities — including many highly selective schools — have adopted test-optional or test-flexible admissions policies, meaning applicants may choose whether to submit SAT or ACT scores. However:
- Policies vary significantly by school and can change from year to year
- Some schools remain test-required, particularly in certain programs or for certain applicant categories (such as international students, homeschooled students, or specific scholarship programs)
- Test-optional does not always mean test-blind — some schools still consider scores if submitted, even if not required
Always check each target university’s current official testing policy directly on its admissions website, since relying on outdated information can lead to submitting an application that doesn’t match a school’s actual current requirements.
Should You Take the SAT or ACT?
Consider taking a standardized test if:
- Your target schools currently require or recommend submitting scores
- You believe a strong score could meaningfully strengthen your application, particularly if other parts of your academic profile are less quantifiable (e.g., an unfamiliar or non-standard high school curriculum)
- You’re applying for scholarships that specifically require or consider standardized test scores
You might consider not submitting scores (at test-optional schools) if your scores don’t reflect your academic ability as strongly as your grades, essays, and other application materials do.
How to Prepare
Take a Diagnostic Test First
Before committing to a preparation plan, take an official practice test for both the SAT and ACT to see which format feels more comfortable and to establish a baseline score.
Use Official Practice Materials
Both the College Board (SAT) and ACT, Inc. provide official practice tests and preparation resources, which most closely reflect actual test content and format compared to third-party materials.
Build a Study Schedule
Consistent, spaced-out practice over several weeks or months is generally more effective than last-minute cramming. Focus preparation time on your weakest areas identified through practice tests.
Consider Additional Support If Needed
Some students benefit from structured test-prep courses, tutoring, or study groups, particularly for building strategies around timing and difficult question types. This is a personal decision based on learning style, budget, and how much particular sections need improvement.
Retaking the Test
Many students take the SAT or ACT more than once, and most universities allow applicants to submit their highest scores through “superscoring” (combining best section scores across multiple test dates) or by simply submitting the single best overall attempt — policies vary by school, so check each university’s specific policy on multiple test attempts.
Frequently Asked Questions
Do I need to take both the SAT and ACT?
No, most universities accept either test equally; you generally only need to take one, based on which format suits you better or which your target schools prefer, if any.
Are test-optional schools truly optional?
Test-optional generally means submitting scores is not required, though policies and how scores are weighted (if submitted) can vary by school — always check official current policy.
How many times can I take the SAT or ACT?
There’s no strict universal limit, though each testing organization has its own registration policies; many students take the test two or three times to try to improve their score.
Do international students need to take the SAT or ACT?
This depends on each university’s specific policy for international applicants, which can differ from domestic testing requirements — always check the official international admissions page of each target school.
Conclusion
The SAT and ACT remain relevant to many U.S. university applications, but their role has become more flexible as test-optional policies have spread across many institutions. Rather than assuming a fixed approach, research each target school’s current testing policy, take a diagnostic test to see which exam format suits you better, and prepare with official materials over a realistic timeline. As always, verify current policies directly on each university’s official admissions website before deciding whether and how to submit test scores.
