I am going to tell you what official United States government data allow us to see about Purdue University-Main Campus, in West Lafayette, Indiana. I am not going to tell you whether it is "good" or "bad"—no file can answer that question. But I will help you understand its size, its real cost, who gets in, who stays, and who finishes. With that, you and your son will be able to put this piece together with the other two that only you know: what he wants to study and what your family can afford.
What kind of school Purdue is, in a few words
Let's start with the basics, because the basics here are not small.
Purdue is a public, four-year university located in West Lafayette, within Tippecanoe County, in the Lafayette-West Lafayette metropolitan area. Keep in mind: being classified as part of a metropolitan area does not mean the campus is right in the center of a large city. If your son plans to live at home and drive every day, do not trust the map: drive the route yourself on a weekday, at the time he would have class. The actual travel time is almost never what Google Maps promises.
The system that classifies universities in this country—Carnegie—places Purdue among the doctoral institutions with the highest level of research activity. It also describes it as a large, primarily residential four-year school: at the time of that classification, between 25 and 49 out of every 100 undergraduate students lived in institution-provided housing, and at least half studied full-time. In its undergraduate admissions profile, Carnegie places it in its "selective" selectivity group.
It is worth saying something here that you will not read in any brochure: Carnegie describes what a school does, using the same rules for everyone. It does not accredit, recommend, or grade anyone. It helps you understand which schools Purdue resembles. The decision is still yours and your son's.
Purdue is also marked in the official government file as a Land Grant Institution, a historic designation shared by only 80 of the 3,012 institutions in this census. It is a real label, but do not use it to measure the support your son will receive. That shows up in things with names: which student center exists, which scholarship applies, who answers the phone in April. Ask directly.
Purdue's size: a city, not a classroom
Here comes the first number that changes how you should picture this place.
In the official fall count, Purdue reported 52,905 enrolled students. It is one of the largest schools among the 519 selective, four-year public universities in this census: at most one in ten has more students than Purdue.
But that large number contains something that should be separated immediately: of those 52,905, 39,864 are undergraduates and 13,041 are graduate students. If your son is entering a bachelor's degree program, the number that matters to him is not the total population of the university community—it is 39,864. Much of what makes Purdue large is made up of people who have already completed a degree and are pursuing a master's degree or doctorate.
Within that undergraduate population, who is sitting in the classroom next to your son? The data say this: out of every 100 students, 42 are women—there are more men than women. There are almost no adult students: only 3 out of every 100 are between 25 and 64 years old. And among first-time students, fewer than half—46 out of every 100—were permanent residents of Indiana. The rest come from other states or other countries.
And here is a fact I cannot soften: 7 out of every 100 undergraduate students are Hispanic or Latino. It is a small minority, and compared with similar schools, Purdue ranks below the midpoint of that group. This does not take Purdue off your son's list. But if he is going to be one of the few, the question he should ask during the visit is not rhetorical: what student group exists for Latino students? Is there a cultural center? Is there someone in the office who speaks Spanish? Having few Latino students does not make the school bad, nor does having many make it good. It is simply a fact about who is enrolled—and his individual experience may look very different from the average.
How the academic year works
Purdue organizes its year into semesters: two long terms of about 15 weeks each. It accepts credit from AP exams, but does not indicate that it accepts credit for "life experience." It also reports accepting credit for military training, and it enrolls high school students in formal dual-enrollment college courses.
A warning that is worth real money: saying that they "accept AP" does not mean they award credit for every exam. This data point does not tell us how many points they require, how many credits they award, or whether those credits count toward your son's specific degree program. Ask for the equivalency evaluation in writing before enrolling. Do not budget for the savings until you have it in hand.
What is studied there, and in what proportions
In a single year, Purdue awarded 8,433 bachelor's degrees, distributed across 26 different fields-of-study families. The family awarding the most degrees was engineering, with 27 out of every 100 degrees awarded that year—no other area comes close, but engineering does not account for the entire school either. Compared with other selective universities, Purdue ranks in the quarter with the greatest variety of fields-of-study families represented in its offerings.
This matters for a specific conversation: if your son has a clear calling outside engineering, Purdue is not just "the engineering school" that someone may have told you it was. But 26 families represented in the report do not mean 26 complete degree programs or guarantee that the exact program your son wants exists—some of those rows may report only a few degrees. Verify the exact program by name before building expectations.
The student-to-instructional-staff ratio is 14 to 1—a low ratio, below the midpoint of its comparable schools. That sounds good, and it is a real data point. But do not confuse it with the size of your son's classes: it is an institutional average and does not show how many students are in a first-year classroom.
Purdue also reports structured academic pathways worth keeping on your radar: study abroad, a complete program that can be taken entirely in the evenings or on weekends, and teacher-certification preparation pathways with state approval.
Getting into Purdue: what they require and what really happens
This is where many families look at only one number and stop. Let's look at the three that truly matter, in order.
First, what the application requires. Purdue does not have open admission. Of nine possible considerations, it marks three as required: the high school record, the personal essay, and an English proficiency exam for applicants to whom it applies. It also considers, though does not require, class rank, the curriculum completed, letters of recommendation, a portfolio or competency exam, and work experience. The published application fee is $60.
Put simply: at Purdue, gathering documents is not enough. The essay is required, so your son has to write—and write well. Have him start in the summer, not the week of the deadline. The first draft is never the one that gets submitted.
The test—SAT or ACT—is also required. Among enrolled first-time students, 73 out of every 100 submitted SAT scores, and among them, the middle half scored between 590 and 710 in reading and writing, and between 600 and 750 in mathematics. If your son's scores are below those numbers, it does not mean he is out—but it is a sign to work on them well in advance, not the week before applying.
Second, who receives an acceptance letter. In the most recent cycle, Purdue received 73,083 first-time applications and offered admission to 36,763 applicants. That is 50 out of every 100. Compared with other selective schools of its type, Purdue is among those that accept the fewest applicants: nine out of ten similar schools accepted a higher percentage of their applicants. The count is split almost in half. Admission is not guaranteed, but it is not a lottery either—the application is reviewed closely.
Third—and this is the number almost no one looks at, but it says something real. Out of every 100 students Purdue admitted, only 26 ultimately enrolled. The other 74 had the letter in hand and did not use it. That places Purdue right in the middle of its comparable schools. This does not measure quality or prestige: it counts decisions made by families who, with the letter already in hand, chose another path—perhaps because of price, distance, or another offer. When your son's admission arrives, this number is a useful reminder: the letter is not the decision. Put the letters from all the schools next to one another and compare net price, degree program, and distance before the deposit deadline.
Regarding transfers: in the most recent fall, 1,084 students arrived at Purdue for the first time after studying at another institution. That is a high number of people compared with similar schools. What this data point does not say is what proportion of those who started at Purdue left for another institution—that departure rate simply was not reported. This does not prove that no one transfers out; it only means that row is blank.
The price: two numbers, and a gap you need to know
At Purdue University-Main Campus, among 340 first-time, full-time, credential-seeking students who received federal Title IV aid, paid the in-state or in-district rate, and whose EFC records showed family income below $30,000, the average net price was $4,927. Among 302 students in the same population with EFC family income from $48,001 to $75,000, it was $8,948; among 689 students with EFC family income above $110,000, it was $21,130. For dependent students, the band combines their parents' income with their own.
There is a difference of $16,203 between the average for the lowest-income band (340 students) and the average for the highest-income band (689 students). These are group averages, not a prediction of your family's price. Among first-year students who received any grant or scholarship aid, the average was $12,421.
Among the 519 schools of the same type and control included in this census that reported this data point with the same time coverage, Purdue falls in the least expensive quarter for the lowest-income families after grants and scholarships are subtracted. That does not mean it will be inexpensive for your family. It is a data point that matters when you build the list of schools to apply to.
Because the price varies so much from one income band to another, correctly identifying yours comes first. The income bands in this profile describe first-time, full-time, credential-seeking students who received federal Title IV aid; at public institutions, they use the in-state or in-district rate. The overall average with grant or scholarship aid, when shown, describes first-time, full-time, credential-seeking students who received federal, state, local, or institutional grants or scholarships. The aid letter you receive is what matters.
Grants, Pell, and loans: who receives what
Out of every 100 degree-seeking students at Purdue, 44 received some grant or scholarship aid that does not have to be repaid. The other 56 did not. Compared with similar schools, Purdue falls in the quarter where grant or scholarship aid reaches fewer students. Among those who did receive it, the annual average was $10,029.
Only 13 out of every 100 received federal Pell Grants—reserved for low-income families. Do not assume one will arrive. Before applying, ask for the complete list of available scholarships, who qualifies for each one, and the deadlines.
Regarding loans: in the most recent academic year, only 23 out of every 100 undergraduate students received a federal loan—the majority did not borrow that year. Among those who did borrow, the average amount was $5,999. This is on the low side compared with similar schools.
But be careful not to read this as an automatic victory. The fact that most students did not borrow does not say how they managed—there may have been grant or scholarship aid, work, family savings, or another type of debt that this report does not record. And the fact that a student received a loan does not mean it covered the entire year; it only says that the student borrowed. That average also does not include the Parent PLUS loans that parents sometimes end up signing for, credit card debt, or the accumulated debt with which a student actually graduates—for that, you would have to add up four or more years, and that number does not exist in this report.
Purdue also reports two specific mechanisms for organizing payment: a tuition installment plan and participation in a Promise-type program.
Life outside the classroom: housing, ROTC, athletics, and support
Purdue does have institution-controlled housing, and it does not require all first-time, full-time students to live there—although that does not rule out the possibility that a specific program may require it. The reported maximum capacity is 16,270 students. It also offers meal plans, with a fixed number of meals per week in the largest plan. Having housing does not guarantee that a bed will be available when you request one: ask for the exact rate, the application deadline, and whether a place is guaranteed or applicants are put on a waiting list.
Purdue indicates ROTC opportunities in all three branches: Army, Navy, and Air Force. That is uncommon—only 135 of the 3,012 universities in this census indicate all three. But that designation does not confirm that the program is offered on this specific campus, that space is available, or that there is a scholarship. Ask about each branch separately, with the full name of the contact person.
It competes in intercollegiate athletics and is affiliated with the NCAA, reporting membership for football, basketball, baseball, and cross-country or track. The affiliation belongs to the school, not to your son: if he is interested in a sport, he needs to write directly to the coach and ask in writing whether there is a place on the team and whether that sport offers scholarships.
Regarding instructional mode: 2 out of every 100 undergraduate students take all their classes remotely—the vast majority, 98 out of every 100, take at least one class in person. Purdue does offer at least one complete distance program, although the data do not confirm its exact level; confirm the degree program and level before assuming anything.
The library operates with paid staff and annual spending above the $100,000 threshold recorded by the government, and it has physical and digital materials and participates in interlibrary lending. That is a baseline, not a guarantee that the specific databases for your son's degree program are available—ask using the program's name.
Purdue also reports academic and career counseling services, employment for current students, job placement for graduates, on-campus child care, participation in the Yellow Ribbon program for veterans, a dedicated point of contact for military families, a student veterans' organization, and a published services page for people with disabilities.
Who stays, and who finishes the degree
This may be the section where a family's peace of mind is most at stake.
Among students who entered a full-time bachelor's degree program in the fall of 2022, 92 out of every 100 were still enrolled one year later or had already completed the degree. It is one of the highest retention rates among its comparable schools. But keep in mind: this number combines two groups—those who are still studying and those who have already graduated—and it does not tell you which is which or what happened to the remaining 8 percent.
As for graduation itself: among the cohort that started in 2017, 83 out of every 100 had earned their degree six years later. At four years—the timeframe most families have budgeted for—the figure drops to 64 out of every 100. Those 19 percentage points of difference between the four-year and six-year marks are not a minor detail: for many families, they represent a fifth year that must be paid for. Before signing anything, ask in writing how long the program your son is interested in usually takes, how its required courses are scheduled, and how the total cost changes if the plan takes longer.
Compared with similar schools, Purdue is among those that graduate the most students: nine out of ten of its peers report an equal or lower proportion.
There is also a third measurement at eight years, following a broader cohort that includes students with prior college experience. Of those students, 78 out of every 100 completed a Purdue degree or certificate. Among those who received a Pell Grant, the figure was 74 out of every 100—five points below the group without Pell Grants. Compared with similar schools, Purdue also ranks in the top quarter on this measure.
None of these numbers predicts what will happen to your son. They describe earlier cohorts under circumstances that have already passed. The value of having them is not to predict the future—it is to use that information to ask the right questions about the program's current support and the outcomes of the most recent cohorts.
What this article cannot tell you
Nothing above tells you what will happen to your son after graduation—not his salary, whether he will be employed, or how much debt he will carry on the day he receives his diploma. That part of the story simply is not in these official data, and anyone who promises it based on these figures is making it up.
It also does not tell you whether Purdue is the right university for your family. That depends on two pieces no government file knows: what your son wants to study and has built so far, and what your family can and is willing to pay.
What I can tell you is this: you now know, from real numbers rather than scattered impressions, what kind of university Purdue is—its size, its actual selectivity, its cost structure, who receives aid and who does not, and what happens to the students who enroll there. Put that together with what your son wants and what you can afford, and you will have not a promise, but a plan.
Your son's job is to write the essay, earn the score, and choose the degree program. Your job is to understand the money, compare the letters when they arrive, and ask the questions these data do not answer. It is not your life being decided here. But you do not have to remain outside the process because you do not know the numbers. Now you know them.
