CLT vs. SAT vs. ACT: Which Test Should You Take?

Last updated: August 2026

A student choosing among the CLT, SAT, and ACT in 2026 is comparing three genuinely different exams, and all three have changed within the past few years. The SAT went digital and section-adaptive in 2024. A year later the ACT shortened its core test and moved Science to an optional add-on, while the CLT, a two-hour exam taken without a calculator and available at home, has expanded well beyond its original base in classical and homeschool education, though its college acceptance remains much narrower than the SAT’s or ACT’s.

I’ve written Barron’s prep guides for the SAT and ACT, and I built the full-length CLT practice test on this site question by question. The comparison below comes from working directly with all three exams; I checked the format, fee, and policy details in this guide against current testing-organization and government sources in August 2026.

CLT vs. SAT vs. ACT at a glance

Fees are base U.S. registration fees as of August 2026. Testing times exclude check-in, instructions, and breaks: the SAT’s figure leaves out its 10-minute break, and the CLT’s remote appointment adds about 20 minutes of pretest setup.

For most students, the first decision remains SAT versus ACT, because both are broadly accepted. The CLT becomes a serious third option when every relevant college and scholarship will use it, or when a student is willing to take the SAT or ACT as well.

Start with your college list

Which tests do the colleges on your list accept? The answer can settle the choice by itself. Colleges that consider standardized tests generally accept both the SAT and ACT and typically state no preference between them, though it still pays to confirm the policies of individual colleges, scholarships, and specialized programs. A growing list of selective schools has also reinstated testing requirements after the test-optional years, a shift I covered in this post on the return of test requirements. Because testing policies keep changing, most students should at least find out which exam gives them their strongest usable score.

The CLT’s footprint is narrower but growing. More than 350 partner colleges accept it. The list is concentrated among private, liberal arts, faith-based, and classical institutions such as Hillsdale, Wheaton, and Pepperdine, though it has broadened to include the U.S. service academies and public universities in several states, along with all 12 universities in Florida’s State University System, whose Board of Governors approved it in September 2023. Florida students can also use the CLT for Bright Futures qualification, dual enrollment eligibility, and graduation requirements.

Texas took a more limited step in July 2026. In a letter to campus leaders, Higher Education Commissioner Wynn Rosser said public universities may currently consider CLT scores as one factor for first-time freshmen who do not qualify for automatic admission under the state’s uniform admission statutes, along with international and returning applicants. The state’s Coordinating Board plans to write the CLT into its admissions rules, with a vote expected by January and the change taking effect for the fall 2028 cycle; that approval is proposed, not settled. A review conducted for the state found all three exams met a baseline standard of rigor and reliability, but it rated the evidence that CLT scores predict college performance at 1.4 out of 4 points, against 3.8 for the ACT and 4 for the SAT. CLT representatives attributed the gap to limited Texas data: reviewers weighed CLT evidence covering 259 students at five private universities against College Board data covering more than 117,000 students.

Do not build a testing plan around the CLT until you have checked every college you might apply to. A test-optional school is not the same thing as a school that formally accepts the CLT in place of the SAT or ACT.

Acceptance also doesn’t always mean the same thing. When you read a college’s policy, notice which kind it describes: accepted for admission, accepted for merit scholarships, accepted by the university but not by every program, accepted for state scholarship or graduation purposes, or merely reviewed as supplemental information. The CLT’s status varies across all five, sometimes at the same school. Do not rely on the CLT as your only admissions test for highly selective universities unless a college explicitly lists it as an approved substitute, and check the partner college list before committing.

How each test works

The digital SAT

The SAT moved to an all-digital, section-adaptive format in the United States in spring 2024. Students test in the College Board’s Bluebook app at a test center or through a school-day administration; there is no at-home option. The test runs 2 hours 14 minutes: a Reading and Writing section built from two 32-minute modules of 27 questions each, then a Math section built from two 35-minute modules of 22 questions each, with a 10-minute break in between.

Section-adaptive means your performance on the first module determines whether the second module carries a generally higher or lower difficulty mix, and routing to the harder version is necessary to reach the highest score ranges. Each module still blends easier and harder questions, though, so don’t try to read your result from how the second module felt, and know that you can’t return to module one once you’ve advanced. The built-in Desmos graphing calculator can be used on every Math question, you may bring your own approved calculator as well, and roughly a quarter of the Math questions require a typed answer rather than a multiple-choice selection. Scores still run 400 to 1600.

The enhanced ACT

ACT introduced its redesigned test in stages, starting with national online administrations in April 2025; by spring 2026 the enhanced format had reached national, international, and state or district testing. The core test has three sections: English (50 questions, 35 minutes), Math (45 questions, 50 minutes), and Reading (36 questions, 40 minutes). That comes to 131 questions in 2 hours 5 minutes, down from 215 questions in roughly 3 hours on the old test, and the design is linear: every student on a given form sees the same fixed sequence.

Science is now an optional 40-question, 40-minute add-on, scored separately on the 1-36 scale, and it no longer factors into the Composite, which is the average of English, Math, and Reading. Math questions dropped from five answer choices to four, and the optional 40-minute Writing essay remains available. Students may also be able to choose between paper and computer testing depending on the administration, a decision I covered in a separate post.

The CLT

The Classic Learning Test is a 120-question, 2-hour exam with three 40-question sections: Verbal Reasoning (40 minutes), Grammar/Writing (35 minutes), and Quantitative Reasoning (45 minutes). No calculator is allowed anywhere on the test, and the scoring is unusually transparent: each of the 120 questions is worth one point toward the 120-point scale, with no guessing penalty.

Individual students can take the CLT at home through remote proctoring: you test on your own laptop or desktop between 7 a.m. and 7 p.m. Eastern on the test date, alone, on camera, at a desk or table, with video and screen recorded for review. Schools can also administer it in person, on computer or on paper, and only in-school testers can add the optional 30-minute essay, which is unscored and simply forwarded to colleges. Scores for remotely proctored exams post on the third Wednesday after the test date. Younger students have parallel options in the CLT10, an alternative to the PSAT for 9th and 10th graders, and the CLT3-8. For a full breakdown of format, scoring, and the at-home testing rules, see my CLT exam guide.

Where the content differs

Reading

This is the sharpest difference among the three tests. CLT Verbal Reasoning uses four passage sets: literature, science, philosophy or religion, and paired historical or founding documents, with ten questions on each. About two-thirds of the CLT’s reading and writing passages come from its published Author Bank, which ranges from Plato and Augustine to Frederick Douglass and C.S. Lewis. In my experience these are the densest passages students encounter on any of the three exams, though the pacing of one minute per question is reasonable. Students do not need to have read these works beforehand: the questions are designed to be answerable from the passage in front of you. Familiarity with older prose helps your speed and comfort, which is a different thing from needing prior knowledge of the texts.

SAT passages are much shorter: dozens of brief selections, most between 25 and 150 words, one question apiece, drawn from a range of genres, with fiction, poetry, and drama excerpts alongside nonfiction on science, social studies, and the humanities. The ACT sits between the two, with longer contemporary passages at about 67 seconds per question, so students who retain details across a full passage hold an advantage there. You can feel the difference directly by trying a few SAT Reading and Writing drills against a few ACT Reading drills; the Verbal Reasoning section of this site’s CLT practice test serves the same purpose for the CLT.

Grammar and writing

All three tests cover similar ground here: punctuation, sentence structure, agreement, transitions, and concision, tested through editing tasks. The presentation differs enough that a student who is strong in English generally can still perform unevenly across the three. ACT English has the fastest nominal pace of any section compared here, at about 42 seconds per question. The SAT presents grammar in short, self-contained questions inside the Reading and Writing modules, and the CLT’s Grammar/Writing section works through longer passages at a middle pace. The underlying rules barely change from test to test, so one review serves all three; the SAT grammar rules guide and ACT grammar rules guide on this site cover the conventions each exam draws from.

Math

The SAT’s Math section leans heavily on algebra and gives you the most support: about 95 seconds per question, with Desmos available throughout. Students who learn which problems Desmos can graph, solve, or check in seconds often pick up points from that skill alone. The ACT generally spreads its questions across a broader slice of the high school math curriculum, from pre-algebra through trigonometry, with your own calculator permitted and less time per question, about 67 seconds. The CLT allows no calculator at all and puts more weight on logical reasoning; its arithmetic stays manageable by design, but students who lean on a calculator for basic computation will feel the absence.

Science

Only the ACT offers a science score, and it’s now optional. The section primarily tests data interpretation, experimental reasoning, and the evaluation of competing scientific viewpoints. Advanced subject knowledge is not required, though some questions draw on basic concepts from introductory biology, chemistry, physics, and Earth and space science. Consider adding Science if you’re applying to colleges or programs that request or recommend it, if you’re a prospective STEM or health-science major who can post a strong score, or if a scholarship you’re chasing considers it. Institutional policies vary, so not every STEM applicant needs it, and students whose target schools don’t ask for it can reasonably skip it. The SAT works some chart and data analysis into its existing sections, and the CLT has no science section, though science passages appear in Verbal Reasoning. If you plan to add ACT Science, the practice drills here cover all three of its question formats.

CLT to SAT and ACT score conversions

CLT publishes a concordance with the SAT, and its ACT comparison is derived from that concordance plus the 2018 joint College Board and ACT study. Converted scores are estimates, not mathematical equivalents; a 100 CLT and a 31 ACT do not mean the student answered the same percentage correctly or faced equivalent questions. Some colleges also maintain their own tables. Selected values:

For students graduating in 2026 or 2027, Florida’s published Bright Futures thresholds align with the CLT concordance: 1330 SAT, 29 ACT, or 95 CLT for Academic Scholars, and 1190 SAT, 24 ACT, or 82 CLT for Medallion Scholars. Bright Futures also permits CLT superscoring across multiple attempts. Superscoring more broadly has no universal answer; colleges decide individually whether and how they superscore each test, so check each school’s policy.

Cost, test dates, and logistics

Older articles describe the CLT as the budget option, but the pricing has flipped. The remotely proctored CLT now costs $112, against $68 for the SAT and $70 for the core ACT ($75 with Science, plus $25 for optional Writing), per each organization’s official fee page as of summer 2026. The CLT fee includes unlimited score sharing. SAT and ACT registration each include four free score reports, subject to each organization’s selection deadlines, and later reports cost extra, though many colleges allow applicants to self-report scores during the application and require an official report only from students who enroll, so reporting fees don’t reach every applicant. Homeschool group members can often get CLT discounts, and all three programs offer fee waivers or financial assistance for students who qualify.

Logistics can matter as much as price. The CLT offers at-home testing on frequent dates, close to monthly, with an open retake policy, a real convenience for homeschool families and for students far from test centers, though the recorded environment and strict room rules suit some students better than others. The SAT requires a test center or school-day administration on a set of national weekend dates through the year. The ACT runs seven national dates a year and is the only one of the three that routinely offers individual registrants a paper option; the CLT can also be administered on paper through participating schools, while the standard SAT is digital. Most national ACT scores post within about two to four weeks, with online testers generally on the faster end and Writing taking longer. SAT scores are typically available within two to four weeks, and remotely proctored CLT scores post on the third Wednesday after the test.

Practice materials for each test

The SAT has the most official free material of the three: multiple full-length adaptive practice tests inside Bluebook, a large official question bank, and structured prep through Khan Academy. ACT posts free practice resources, including full-length practice tests, section quizzes, and sample questions, and offers additional free prep through a partnership with Kaplan; its paid Official ACT Prep Guide 2026-2027 contains four full-length tests in the current format. CLT provides three full-length official practice tests at no charge through a student account, timed like the real exam and with explanations, plus a test simulation that walks through the remote-proctoring setup before test day.

This site adds original practice to supplement those official materials. The SAT section contains hundreds of drills across Math and Reading and Writing, along with vocabulary flashcards and a Hard series for students targeting the upper score ranges. There is also practice for all four ACT sections, ACT Math flashcards, and a full-length, 120-question CLT practice test with an explanation for every answer.

Which test fits you?

A practice score matters more than any general profile, but these patterns hold up often enough to be useful.

Consider the CLT when:

• Every college you’re seriously considering accepts it, or you’ll pair it with an SAT or ACT score
• You’re comfortable reading classic and historically styled texts
• Careful reading, grammar, and logical reasoning are strengths
• You can handle math without a calculator
• At-home testing on frequent dates is a real advantage for your family
• A partner college ties meaningful scholarships to CLT scores

Consider the ACT when:

• You work quickly and decisively under time pressure
• You prefer longer passages with several related questions
• Your math is solid across the full high school curriculum
• You want a science score for STEM-leaning applications
• You prefer paper testing, or want the choice of paper or online where available

Consider the SAT when:

• You prefer short reading selections over long passages
• You benefit from having the most time per question
• Algebra and data analysis are strengths
• You’re fluent with Desmos, or willing to become fluent
• You want the largest supply of official free practice material

A five-step way to decide

1. Identify which colleges and scholarships will use each test. Do not make the CLT your only test if any serious option on your list will not accept it.
2. Take one timed official practice test in each remaining format; when official material runs short, use a full-length test built to the current blueprint.
3. Compare properly scaled scores against the ranges of your prospective colleges, using the CLT concordance as a rough guide rather than an exact conversion.
4. Weigh comfort alongside scores: pacing stress, fatigue, and how each format felt.
5. Commit your prep time to the strongest option instead of splitting it three ways indefinitely.

Start with the college list, then take a timed practice test in each eligible format. Treat the score conversions as rough comparisons rather than exact equivalents. Once one test produces the strongest usable result, concentrate your preparation there.

Frequently asked questions

Is the CLT easier than the SAT or ACT?

No test is universally easier. Concordance tables help compare score ranges, but they do not prove that the exams are equally difficult. The CLT emphasizes older prose and no-calculator reasoning. The ACT has the fastest overall pace, while the SAT uses short passages, adaptive modules, and calculator-permitted math. The easiest test for a particular student depends on that student’s strengths.

Do you need to know classic literature to do well on the CLT?

No. The questions are designed to be answerable from the passage in front of you, so prior knowledge of the specific works is not required. Comfort with older sentence structures and vocabulary does help with speed, and reading older prose alongside full-length practice tests can build that familiarity.

Do Ivy League colleges accept the CLT instead of the SAT or ACT?

No. Every Ivy League college has now reinstated standardized testing: six of the eight require SAT or ACT scores for the 2026-27 application cycle, and Princeton and Columbia, the last two holdouts, require them beginning with the 2027-28 cycle. None lists the CLT among the accepted exams, so students aiming at these schools should plan on the SAT or ACT.

What does a CLT score convert to on the SAT or ACT?

Per the CLT-published concordance, a 95 CLT is about a 1330 SAT or 29 ACT, a 100 is about a 1390 or 31, and a 105 is about a 1460 or 33. The full table above covers the range from 60 to 120, and converted scores are estimates rather than exact equivalents.

Does the CLT have a science section?

No. The CLT tests verbal reasoning, grammar and writing, and quantitative reasoning only, though science passages do appear in its Verbal Reasoning section as reading material. The ACT is the only one of the three exams with a science score, and that section is now an optional add-on.

Can I take more than one of these tests?

Yes, and many students do. Many colleges allow applicants to choose which scores to report, though score-choice, superscoring, and all-scores policies vary by institution, so check each school before deciding what to send. The CLT has an open retake policy with frequent test dates.

Which test is cheapest?

The SAT, at $68, with the core ACT close behind at $70. The remotely proctored CLT costs $112, though that includes unlimited score sends, and discounts are available through many homeschool networks. Fees change by testing year, so confirm on each organization’s official site before registering.
