Purdue's School of Aeronautics and Astronautics has a claim few engineering programs anywhere can match: Purdue has graduated more astronauts than any university other than the US service academies, including Neil Armstrong, the first person to walk on the Moon, who earned his BS in Aeronautical Engineering here. That legacy sits inside one of the largest and most highly ranked engineering schools in the US, with deep, decades-long recruiting relationships across aerospace, defense, and automotive employers. This guide covers what it takes to get into Purdue's Aeronautical and Astronautical Engineering program, what it costs, English-test rules, and where graduates go.
Acceptance Rate
Purdue does not publish a major-specific acceptance rate for Aeronautical and Astronautical Engineering:
- Purdue's overall undergraduate acceptance rate is approximately 43.4%, notably higher than most other selective US universities.
- Purdue's own admissions guidance flags its most selective majors, including Aerospace Engineering and Computer Science, as drawing "disproportionately high application volume relative to available seats" even though there is no separate admit-rate figure published for the major itself.
- Applicants should treat the university-wide 43.4% as a starting reference point only, not as their actual odds into this specific, highly sought-after program.
Bottom line: treat 43.4% as the honest, university-wide figure since Purdue does not release a program-specific acceptance rate for Aeronautical and Astronautical Engineering. Given the program's astronaut pedigree and strong industry ties, applicants should build a file that would stand out even at a meaningfully more selective admit rate than the university-wide average.
Fees and Cost of Attendance
Purdue is notable for holding tuition largely flat for well over a decade, making it one of the more cost-effective top-ranked US engineering destinations for international students:
| Cost Item | Amount (USD/year) |
|---|---|
| International tuition | $30,500 |
| Living expenses | $12,500 |
| Total estimated cost of attendance | $43,000 |
For a four-year BS, that's roughly $170,000-$175,000 total before financial aid, meaningfully lower than many comparably ranked private engineering programs. Purdue's application fee is $60. Purdue also offers an MS in Aeronautics and Astronautics at the graduate level, priced at the same representative international estimate of roughly $30,500/year, since Purdue's tuition is comparatively uniform across levels relative to peer schools; graduate applicants pursuing a funded teaching or research assistantship can have this tuition substantially or fully covered along with a stipend.
Admission Requirements
Based on Purdue's published undergraduate international-applicant requirements:
- Common Application or Purdue's own application portal
- Official high school transcript
- SAT or ACT scores (test-optional policy in effect; confirm current cycle status)
- English proficiency test scores (IELTS/TOEFL/Duolingo/PTE) for applicants not schooled primarily in English
- Application fee or fee waiver request
Purdue does not publish a minimum GPA, but the middle-50% SAT range for admitted students is 1220-1480, with the middle-50% ACT range at 28-34; competitive Aerospace applicants typically present scores toward the higher end of these ranges given the major's popularity. Early Action closes November 1 (decisions late January); Regular Decision closes January 15 (rolling decisions through spring; note that some competitive majors close earlier).
How to Get Into Purdue's Aeronautical and Astronautical Engineering Program
-
Don't treat Purdue's university-wide acceptance rate as your odds. Purdue's own admissions guidance explicitly flags Aerospace Engineering as one of its most oversubscribed majors; build your application as if targeting a considerably more selective program than the 43.4% headline figure suggests.
-
Show demonstrated interest in aerospace specifically. Robotics, rocketry clubs, flight simulation, competitive physics or engineering competitions, or substantial personal projects all signal genuine fit with a program whose culture is built around "Cradle of Astronauts" branding and student rocketry teams.
-
Don't underweight English-test prep just because the bar looks accessible. Purdue's undergraduate IELTS/TOEFL minimum (6.5/79) is comparatively low for a top-ranked engineering school, but the real risk shows up later, in first-year technical writing and lab-report coursework, not at the admissions stage.
-
Apply early relative to the November 1 or January 15 deadlines. Some competitive majors, which Aerospace Engineering is one of, can effectively fill consideration slots ahead of the general regular-decision deadline.
-
If considering the graduate MS route, plan for a possible funded assistantship early. Purdue's departments award Graduate Teaching and Research Assistantships that typically cover full tuition plus a stipend, awarded competitively and often on a rolling basis ahead of general admission decisions.
English Proficiency Requirement (IELTS/TOEFL)
Purdue's undergraduate English-proficiency requirement is comparatively moderate relative to peer top-100 engineering schools:
- IELTS: minimum 6.5 overall, recommended 6.5
- TOEFL: minimum 79 overall, recommended 79
- Waiver: applicants who completed secondary education taught primarily in English, including at an accredited US high school, are generally exempt
- Purdue does not offer conditional or pathway admission for undergraduate applicants below these thresholds
At the graduate level, requirements are set departmentally rather than as one university-wide number: the general graduate minimum is IELTS 6.5/TOEFL 77, but the College of Engineering's own guidance (which Aeronautics and Astronautics falls under) runs up to TOEFL 88. Applicants seeking a funded Teaching Assistantship should also expect a separate spoken English proficiency assessment (for example, a TOEFL Speaking sub-score of 26+ or an internal Purdue speaking test) beyond the standard admissions requirement. For general context on applying to Purdue, see the Purdue University guide.
Career Outcomes
Purdue does not publish a program-specific employment rate or average starting salary for Aeronautical and Astronautical Engineering, but the university's undergraduate top recruiters list is unusually well matched to this program specifically:
- Top recruiters (Purdue undergraduate, university-wide): Boeing, Rolls-Royce, Cummins, Microsoft, General Motors, NASA
- Purdue's aerospace heritage runs deep: alongside Neil Armstrong, Eugene Cernan (the last person to walk on the Moon) earned his BS in Electrical Engineering here, and Gus Grissom, one of NASA's original Mercury Seven astronauts, earned his BS in Mechanical Engineering here
- Purdue's growing investment in semiconductor and microelectronics programs, alongside new chip-manufacturing investment in Indiana, is creating additional adjacent opportunity for aerospace-adjacent engineering graduates in avionics and systems roles
Given the direct presence of Boeing, Rolls-Royce, and NASA on Purdue's own recruiter list, Aeronautical and Astronautical Engineering graduates are especially well positioned relative to Purdue's broader engineering cohort.
