SAT vs. ACT: What Families Need to Know

3/4/2026

 
By Lisa Hillhouse, Hillhouse College and Career Advising
For many families, standardized testing feels confusing and stressful. Should your student take the SAT? The ACT? Both? When should they start? Do these tests even matter anymore?
Let’s break it down.

What Is the SAT?
​

The SAT (administered by the College Board) is a standardized college admissions exam used by colleges and universities in the United States.
Here is the current SAT Structure:
  • Reading & Writing (combined section)
  • Math
  • Total score range: 400–1600
The SAT is now fully digital and adaptive, meaning the difficulty level adjusts based on student performance.

​What Is the ACT?

The ACT (administered by ACT, Inc.) is another standardized admissions test accepted at four-year colleges in the U.S.

ACT Structure
  • English
  • Math
  • Reading
  • Science
  • Optional Writing section
  • Composite score range: 1–36
Unlike the SAT, the ACT includes a dedicated science section (focused on data interpretation and scientific reasoning).

Key Differences Between the SAT and ACT
​
Here’s what I explain to my students:
SAT
  • 2 Sections (Reading & Writing, Math)
  • Adaptive Digital Test
  • Slightly more time per question
  • Math section allows calculator throughout
  • No stand alone science section
  • More advanced vocabulary/more complex writing
  • Digital format only
ACT
  • 4 Sections (English, Math, Reading, Science)
  • Fixed format (not adaptive)
  • Faster Pacing
  • Some math questions may limit calculator use
  • Dedicated science reasoning section
  • Larger % of geometry in the math section
  • Students choose from a print or a digital format


​
Colleges do not prefer one test over the other. Both are accepted equally.
The real question is: Which test fits your student’s strengths?

When Should Students Decide Which Test Is Right?
Ideally, students should begin exploring testing during:

Sophomore Year (Spring)
  • Take a full-length diagnostic SAT and ACT
  • Compare scores using concordance tables
  • Assess pacing comfort and section preferences​
  • Decide which test they want to prepare for and take

​By late sophomore year or early junior year, most students should commit to one primary test.
Waiting until senior year to “figure it out” creates unnecessary pressure. Note: If a student is in Algebra 2 junior year, prepping and testing will happen later than those students in more advanced math.

When and How Should Students Prepare?
In my advising practice, I recommend:

Step 1: Diagnostic Testing
Take one full SAT and one full ACT practice exams under timed conditions at the end of sophomore year. That allows students time to prep in the summer if they want to start testing in the fall..

Step 2: Choose a Primary Test
Select the test that:
  • Feels more natural
  • Produces the stronger percentile score
  • Aligns with academic strengths (math, reading, etc.)

Step 3: Structured Preparation (3–4 Months plus)
  • Systematic weekly practice sessions (ideally 3 times a week)
  • Timed section drills
  • Full-length practice tests every 4 weeks
  • Targeted skill review (math content gaps, grammar rules, etc.)

​Ideal Timeline
  • First official test: Late summer or the fall of junior year. Review scores/prepare plan to strengthen deficiencies
  • Retest: Winter/Spring of junior year
  • Final opportunity: Summer and early fall of senior year

Students who prepare early are calmer, more confident, and often require fewer retakes. Remember that the fall of senior year is a busy time with college applications, academics, and social activities.. Finding time to test prep then is challenging.

Why Are These Tests Important in Admissions?
Even in the era of “test-optional,” standardized tests still matter.
Here’s why:

1. Academic Readiness Indicator
Admissions offices use scores to assess:
  • College-level math readiness
  • Reading comprehension
  • Writing mechanics
  • Academic talents
More and more colleges are returning to standardized test-taking, including Southern and Midwestern flagships. Examples include Purdue University, the University of Georgia, and the University of Tennessee. Most of the Ivy League institutions are again requiring them. 

2. Merit Scholarship Consideration
Many colleges use SAT/ACT scores to award merit-based scholarships — sometimes automatically.
Strong scores can mean:
  • Thousands (or tens of thousands) of dollars per year
  • Honors college invitations

Better chances of admission in impacted and competitive majors like engineering, computer science, nursing and business

3. Institutional Reporting 
Colleges report test score averages for rankings and accreditation. Strong test score applicants help strengthen a school’s profile and can sometimes aid a slightly weaker academic profile. Schools not requiring them may highly encourage students to take them. Applicants with lower scores may choose to not submit. But those with higher scores are helping raise college academic profiles. This can inflate score averages (FYI) but an also benefit strong test takers.


4. Military and ROTC Programs
F
or students pursuing ROTC scholarships or Service Academies, strong test scores remain a significant factor in competitiveness.

Do Students Still Need to Test If Colleges Are Test-Optional?
“Test-optional” does not mean “test-blind.”

​At many institutions:
  • High scores can strengthen an application.
  • Low scores can be withheld.
  • Scholarship decisions may still require scores.

​Testing gives students options.

Final Thoughts for Families
Standardized testing should not drive your student’s identity or self-worth. However, thoughtful planning and practicing around testing can:
  • Increase admissions options
  • Expand scholarship opportunities
  • Reduce senior-year stress
  • Provide measurable academic feedback

​The key is early exposure, strategic preparation, and informed decision-making.

Need Help Deciding Between the SAT and ACT?

Every student is different. If your family would like guidance on diagnostics, test selection, or building a preparation timeline that fits into your larger college roadmap, I invite you to schedule a complimentary consultation. Together, we’ll create a plan that supports your student’s strengths — and reduces the overwhelm.
