Let's be real. Applying to college used to be a lot more predictable before the world flipped upside down in 2020. For a minute there, almost every major university in the country went "test-optional," and we all thought maybe the era of sweating over a Scantron was finally over. But then things shifted back. Purdue University, specifically, made a pretty loud statement by being one of the first big-name public institutions to bring back the hammer.
If you’re looking at West Lafayette for your future, you need to understand that Purdue SAT and ACT requirements aren't just a suggestion anymore. They are a hard reality.
I’ve spent years watching admissions trends, and Purdue is unique. They aren't like some liberal arts colleges that might look at your "vibes" or your extracurriculars to excuse a low score. They’re a STEM powerhouse. They like data. They like numbers. And honestly? They really like seeing high math scores.
The Return of Required Testing
It’s official. Purdue University requires either the SAT or the ACT for all undergraduate applicants. This isn't brand new for 2026, but the way they're weighing these scores against a massive surge in applications is changing the game for high schoolers.
Why did they do it?
Admissions officers, including Purdue’s own leadership like President Mung Chiang, have pointed to the fact that standardized test scores—when paired with high school GPA—are simply the best predictor of whether a student will actually pass their freshman year. It sounds harsh. It kind of is. But when you’re applying to a school where the engineering and computer science programs are notoriously "weeder" heavy, the university wants to know you can handle the rigor.
Don't think of it as a barrier. Think of it as a benchmark.
If you're applying for the Fall 2026 or Spring 2027 terms, you basically have to submit a score. There are very few exceptions, mostly involving international students in specific regions or adult learners who have been out of school for a long time. For the average 17-year-old in Indiana or California, there is no way around it.
Cracking the Code on Purdue SAT and ACT Requirements
What's a "good" score? That's the question everyone asks, and the answer is annoying: it depends.
If you are looking at the College of Agriculture, your score needs are going to look a lot different than if you're trying to get into the College of Engineering. Let's look at the middle 50% ranges. This is the "sweet spot" where half of the admitted students fall.
For the SAT, the middle 50% generally hovers between 1210 and 1450.
On the ACT, you're looking at a composite range of 27 to 34.
But wait. If you see those numbers and think, "Oh, I have a 1250, I’m safe for Engineering," you are unfortunately mistaken. Those are university-wide averages. Purdue is a collection of smaller "colleges," and they admit by major. This is a critical distinction.
The Engineering and CS Reality Check
If you want to be a Boiler in the College of Engineering, you should probably ignore the lower end of those averages. Most successful applicants to the top-tier programs are bringing SAT Math scores of 720-800 to the table.
I’ve seen students with a 1350 get rejected because their math subscore was a 610. Purdue looks at the breakdown. They want to see that you can handle calculus, physics, and the heavy lifting. For the ACT, a math subscore below 28 is going to make an engineering application look very shaky, even if your English score is a perfect 36.
Superscoring: The Silver Lining
Here is some actually good news. Purdue superscores.
What does that mean for you? Basically, if you took the SAT in March and got a great reading score but a "meh" math score, and then took it again in June and flipped those results, Purdue will take the highest from each. They create a new, "super" composite score for you.
They do the same for the ACT.
This means you should absolutely take the test more than once. There is zero penalty for sending multiple scores. In fact, it shows persistence. Most students see a jump in their score the second time they sit for the exam just because the "fear of the unknown" is gone.
When "Good" Isn't Enough: Holistic Review
It would be a mistake to think that Purdue SAT and ACT requirements are the only thing that matters. Purdue uses something called "Holistic Review."
It’s a fancy term for "we look at the whole human."

They look at:
- The rigor of your high school curriculum (Did you take the hardest classes available?).
- Your GPA (specifically in core subjects).
- Your personal essay (don't make it boring).
- Your extracurricular involvement.
- Your "Major-Specific" readiness.
If you have a 1550 SAT but you have a 2.5 GPA, you aren't getting in. Conversely, if you have a 4.0 GPA but your SAT is a 1050, Purdue is going to worry that your high school was "easy" and that you aren't prepared for the speed of college-level courses. They want the scores to validate the grades.
The "Pur-doers" Mentality
There is a specific vibe Purdue looks for. They call their students "Boilermakers," and they take that "maker" part seriously. They want people who do stuff. If your test scores are on the lower end of the middle 50%, your "extra" stuff needs to be incredible.
Did you build a robot? Did you lead a 4-H project? Did you work 20 hours a week at a local diner while keeping your grades up? Tell them that. Purdue values grit.
Self-Reporting: Save Your Money (For Now)
One of the best things Purdue does for your wallet is allowing self-reported scores.
You do not need to pay the College Board or ACT to send official reports when you first apply. You just type your scores into the Common App or the Purdue application portal. You only have to pay for the official "verified" reports if you are actually admitted and choose to enroll.
This is a huge win. It allows you to apply to multiple schools without racking up hundreds of dollars in "sending fees" before you even know if you’re accepted. Just... don't lie. If your self-reported score says 1500 and your official report comes in at 1300, they will rescind your admission faster than you can say "Hail Purdue."
International and Out-of-State Perspectives
If you’re an international student, the Purdue SAT and ACT requirements still apply, but you also have to deal with English proficiency.
Purdue accepts the TOEFL, IELTS, or Duolingo English Test. However, if you score high enough on the SAT Evidence-Based Reading and Writing section (usually a 33 or higher), they might waive the extra English test. It's worth checking the specific requirements for your country, as they can get a bit granular.
For out-of-state American students, the bar is often slightly higher than for Indiana residents. Purdue is a land-grant university, meaning they have a mission to serve the people of Indiana first. If you’re coming from New Jersey or Texas, your scores generally need to be in the upper half of those middle 50% ranges to be competitive, especially for the high-demand majors.
The Deadline Trap
You cannot talk about scores without talking about the November 1 Early Action deadline.
If you want to be considered for:
- The Honors College.
- Merit scholarships.
- High-demand majors (CS, Flight, Engineering, Nursing).
You must apply by November 1.
This means you need to have your SAT or ACT taken by October at the very latest. If you wait for the December test date, your scores won't arrive in time for Early Action. You’ll be moved to Regular Decision, and for programs like Computer Science, the seats might already be gone.
Honestly, aim to have your testing finished by the end of your Junior year. It makes your Senior year autumn so much less stressful.
What if you can't get a test date?
In very rare cases, if there is a massive disruption (like a natural disaster), Purdue might offer flexibility. But generally? They expect you to find a way. If you live in an area where testing centers are full, start looking at centers two hours away. It's a hassle, but for a school like Purdue, it’s a necessary one.
A Note on the "Digital SAT"
Since the SAT went digital, the format has changed. It's shorter. It's adaptive.
Purdue doesn't care if you took the "old" paper version or the "new" digital version. They treat the scores the same. Some students find the digital version easier because of the built-in graphing calculator and shorter reading passages. Others hate it. Regardless of your preference, the score is what lands on the admissions officer's desk.
Actionable Steps for Your Purdue Application
Don't just read this and stress out. Do something about it. Here is the path forward if you’re serious about becoming a Boilermaker.
First, take a diagnostic test. Download a free practice SAT and a free practice ACT. Take them under timed conditions. See which one you naturally perform better on. Most people have a "better" test. Purdue doesn't prefer one over the other, so play to your strengths.
Second, target your math. Because Purdue is so STEM-heavy, a high math score carries a lot of weight across almost all majors. Even for Liberal Arts or Business, a strong math score shows "quantitative readiness." Spend 70% of your study time on the math sections.
Third, document your "Why Purdue." When you fill out the application, you'll have to answer why you want to go there. Don't just say "it's a good school." Reference specific labs, the "Cradle of Astronauts," or the specific curriculum of your major. They want to see that your test scores are going to a student who actually wants to be there.

Fourth, watch the calendar. If you’re a junior, register for the spring sittings now. If you’re a senior and it’s already September, get that October registration in immediately.
Finally, keep your grades up. A 1600 SAT won't save a plummeting GPA. Consistency is what gets you through the door at West Lafayette.
Purdue is getting harder to get into every single year. The application volume is record-breaking. By handling the Purdue SAT and ACT requirements early and aggressively, you give yourself the best possible shot at wearing the old gold and black.
