If you're preparing to apply to a US university for the 2026/2027 academic year, you'll eventually run into the same question: which exams do you actually need — SAT, TOEFL, the Duolingo English Test, or all of them? The confusion gets worse because Common App for the new cycle opened on August 1, 2026, which means essay planning now stacks on top of test planning. This guide breaks down what these exams actually measure, what changed with TOEFL and Duolingo heading into 2026, whether you need the SAT at all, and what's worth knowing about the new Common App cycle right now.
Quick answer: what you need to know in 60 seconds
SAT and TOEFL/Duolingo aren't alternatives to each other — they test different things. The SAT measures general academic readiness (math and reading/writing); TOEFL and the Duolingo English Test (DET) measure English proficiency. Most international applicants need one exam from each category (and sometimes not even the first one).
The SAT isn't required everywhere. Over 90% of ranked US colleges remain test-optional for fall 2026 admission. But the list of schools that have reinstated required SAT/ACT scores keeps growing: MIT, Dartmouth, Brown, Cornell, Harvard, Stanford, Penn, Caltech, and several large public university systems (Florida, Georgia, Tennessee).
TOEFL switched to a new scoring scale in January 2026 — 1 to 6 instead of the familiar 0–120, mapped directly to CEFR levels. Through January 2028, score reports will show all three: the new 1–6 scale, the CEFR level, and an approximate 0–120 equivalent.
The Duolingo English Test is the fastest and cheapest option: $70, fully online, about an hour total, results in 48 hours. It's accepted by more than 5,500 institutions worldwide — but check whether your specific school accepts it before relying on it, since some of the most selective programs still require TOEFL or IELTS.
The new Common App cycle (2026/2027) opened on August 1, 2026. One detail a lot of guides miss: the essay prompts didn't change from last year — same 7 options, 250–650 words.
These aren't the same thing: what you're actually comparing
Before comparing specific exams, it helps to separate the two different jobs universities are using them for:
Academic readiness — how strong your math and analytical/reading skills are. That's what the SAT measures (or the ACT, its widely accepted alternative).
English proficiency — a near-universal requirement for international applicants whose secondary schooling wasn't in English. That's what TOEFL iBT, IELTS, and the Duolingo English Test measure.
So "SAT or TOEFL" is really two separate decisions in disguise: whether you need the SAT at all, and which English proficiency exam to take. Let's go through both.
The SAT: do you actually need it for 2026/2027?
Format and cost
The Digital SAT is computer-based, takes about 2 hours 14 minutes, and has two sections — Reading and Writing, and Math — both adaptive, meaning question difficulty adjusts based on your answers as you go.
Base registration fee: $68.
Testing outside the US adds an international fee of about $43, so the total cost for an applicant testing abroad is usually around $110–115.
Whether you need it depends on your list
If every school on your list is test-optional (and per FairTest data, that's more than 90% of ranked colleges for the 2026 cycle) — you can technically apply without an SAT score. But if your score is strong (in the upper half of a school's admitted-student range), it's usually worth submitting anyway, since it only strengthens your application.
If even one school on your list requires the SAT — you'll need to take it. That currently includes MIT, Dartmouth, Brown, Cornell, Harvard, Stanford, Penn, and Caltech, along with several schools in the Florida, Georgia, and Tennessee public university systems.
If you're applying for merit scholarships — many merit-based scholarship programs still require SAT/ACT scores regardless of the university's general admissions policy.
The practical takeaway: even if your whole list is test-optional, it's often worth taking the SAT as a backup — in case your school list changes closer to deadlines, or as leverage for a scholarship application.
TOEFL or Duolingo: how to choose your English exam
TOEFL iBT: what changed heading into 2026
TOEFL iBT, ETS's test, covers four sections (Reading, Listening, Speaking, Writing), historically scored on a 0–120 scale. As of January 2026, ETS introduced a new 1–6 scale in half-point increments, mapped directly to CEFR levels (a score of 5, for example, corresponds to C1). Through January 2028, score reports will show all three metrics at once — the new 1–6 scale, the CEFR level, and an approximate 0–120 equivalent — specifically so admissions offices have time to adjust to the new system.
Cost: typically $235–255 in the US, but the exact fee varies significantly by testing country — check the official ETS site for your location.
Format: about 2 hours, covering all four skills (reading, listening, speaking, writing).
Recognition: accepted by virtually every US university without restriction, including the most selective programs.
Duolingo English Test: fast and cheap, but not universal
The Duolingo English Test (DET) is a fully online exam you can take from home, any time.
Cost: $70 — notably cheaper than TOEFL or IELTS.
Format: about an hour total, including an adaptive section with varied question types (Read and Select, Fill in the Blanks, Write About a Photo, Listen and Type) and a short video interview plus a writing sample.
Results: delivered within 48 hours — much faster than TOEFL or IELTS.
Recognition: currently accepted by more than 5,500 institutions worldwide, including many US universities. But not every top program accepts DET on equal footing with TOEFL yet — always confirm the specific policy on your target school's admissions website before betting on this exam alone.
Comparison table: SAT, TOEFL, and Duolingo English Test
Factor | SAT | TOEFL iBT | Duolingo English Test |
What it measures | Academic readiness (math, reading/writing) | English proficiency | English proficiency |
Cost | ~$68 (+ ~$43 testing outside the US) | ~$235–255 (varies by country) | $70 |
Duration | ~2 hours 14 minutes | ~2 hours | ~1 hour |
Format | Computer-based, adaptive, test center | Computer-based, test center | Online, from home, any time |
Time to results | Usually up to 2 weeks | About 4–8 days | Up to 48 hours |
Required? | Not at 90%+ of schools, but required at some top schools (MIT, Harvard, Stanford, etc.) | One of the standard ways to prove English proficiency | Growing but not yet universal acceptance |
Best for | Applicants to test-required schools, or those applying for scholarships | Applicants who want maximum, no-risk recognition | Applicants who value speed, cost, and convenience — if the school accepts DET |
How to decide: a few diagnostic questions
Does even one school on your list require test scores? If yes, you need the SAT — regardless of the policy at your other schools.
Are you applying for a merit-based scholarship? If so, check its requirements separately: many scholarship programs require SAT/ACT scores even when the university itself is test-optional.
Have you confirmed each school's official DET policy? Admissions offices update their accepted language test lists periodically — check the current policy on the school's own site rather than relying on general "how many schools accept DET" rankings.
What matters more — speed and cost, or maximum universal acceptance? If you're on a tight timeline or budget and your schools accept DET, it's a reasonable choice. If any school on your list only accepts TOEFL/IELTS, or you're not 100% certain of your final list yet, TOEFL is the safer default.
Common App 2026/2027: what changed on August 1
The new Common App cycle — the platform most US university applications go through — opened on August 1, 2026. A few facts worth knowing right now:
The essay prompts didn't change. Contrary to what a lot of early-cycle articles assume, all 7 essay prompts for 2026/2027 are the same as last cycle's — including the familiar "Topic of Your Choice" option. If you started drafting an essay last year, that draft is still usable.
The main essay's word count runs from 250 to 650 words, with 500–650 generally considered the ideal target.
Plan your exams and your essay in parallel, not one after the other. While you're preparing for the SAT, TOEFL, or DET, it's worth picking an essay topic and starting a first draft now — that way, once test results come in, you're not scrambling to do everything else in the final month before Early Decision/Early Action deadlines (typically early November).
What to do: an August 2026 checklist
Draft a preliminary school list and check each school's official SAT/ACT policy and accepted language exams (test-optional, test-required, which language tests are accepted).
If even one school on your list is test-required, schedule your SAT with room for a possible retake.
Choose between TOEFL and Duolingo based on the actual requirements of the schools on your list — not general test reputation.
Create your Common App account and look through all 7 essay prompts — pick a topic and start a draft alongside your exam prep.
Cross-check every exam registration deadline against your application deadlines (especially Early Decision/Early Action) — TOEFL and SAT scores need to be received by the university before the deadline, not just taken by then.
Frequently asked questions about SAT, TOEFL, Duolingo, and Common App
Are the SAT and TOEFL the same kind of exam? No. The SAT measures academic readiness (math and reading/writing skills), while TOEFL measures English proficiency. International applicants typically need at least the language exam, and the SAT depending on the specific requirements of the schools they're applying to.
Do I need to take the SAT if every school on my list is test-optional? Not formally, but if your score is strong, it's usually worth submitting anyway — it can strengthen your application. Also check whether any scholarships you're applying for require SAT/ACT scores.
What changed with TOEFL heading into 2026? As of January 2026, TOEFL iBT switched to a new 1–6 scoring scale mapped to CEFR levels. Through January 2028, score reports show the new scale, the CEFR level, and an approximate 0–120 equivalent all at once.
Do all US universities accept the Duolingo English Test? No. DET is currently accepted by more than 5,500 institutions worldwide, including many US universities, but not all — particularly among the most selective programs. Always confirm the specific policy at each school on your list before relying on DET alone.
Did the Common App essay prompts change for the 2026/2027 cycle? No — all 7 essay prompts are the same as last cycle. The new Common App cycle opened on August 1, 2026.
Which is faster and cheaper — TOEFL or Duolingo? The Duolingo English Test is cheaper ($70 vs. roughly $235–255 for TOEFL) and results arrive faster (48 hours vs. 4–8 days), but it currently has more limited acceptance among the most selective programs.
