Purdue does not publish a separate acceptance rate for its Computer Science major — a fact that surprises a lot of applicants searching for one specific number. What Purdue does publish is its overall university acceptance rate (43.4% for the Fall 2025 entering class) and, more usefully for gauging CS specifically, hard GPA and coursework standards for students trying to enter the major after starting elsewhere at Purdue. Those internal standards are the closest real substitute for a "CS acceptance rate" that exists.

Does Purdue Publish a Computer Science-Specific Acceptance Rate?
No. Purdue's own admissions pages don't break out a per-major acceptance rate for first-year applicants, and its Computer Science department confirms freshman-specific admission statistics for CS aren't published separately from the university's overall numbers. If you see a specific "Purdue CS acceptance rate" percentage cited elsewhere online, treat it skeptically — it's very likely an estimate or guess, not a figure Purdue has actually released.
Purdue University's Overall Acceptance Rate
Purdue admitted 43.4% of applicants for its Fall 2025 entering class (Class of 2029), from roughly 86,953 total applicants. That blended figure splits sharply by residency: approximately 71% for Indiana residents versus approximately 39% for out-of-state applicants. The enrolled class averaged a 3.81 GPA and 1,337 SAT, with the admitted middle 50% ranging from 1220–1480 SAT and 28–34 ACT, and a GPA range of 3.70–4.00; 97% of admits submitted test scores despite Purdue's test-optional policy. Since CS applicants aren't broken out separately, this university-wide profile is the most concrete benchmark available for a first-year CS applicant — a similar pattern to how public flagships like the University of Michigan report admissions data, where overall figures likewise stand in for major-specific ones that aren't officially released.
How Selective Is Purdue CS Really? Three Proxy Data Points
Purdue's Computer Science major sits in the College of Science and is applied to directly as a first-year major choice, but the department is explicit that admission review for later category — changing into CS after starting in a different major — is genuinely competitive, and this is where Purdue actually publishes hard numbers:
External transfer applicants (students transferring in from another college) need a minimum 3.5 GPA plus specific coursework completed with a B or higher — Purdue's own language describes the process as "selective," admitting "the most qualified students... from the pool of applicants."
Internal CODO (Change of Major) applicants — Purdue students in a different major who want to switch into CS — need a minimum 3.00 cumulative GPA for the strongest consideration, must have completed CS 18000 (ideally with an A-) and an approved Calculus course with a B or better, and are evaluated purely on these academic metrics — Purdue explicitly does not consider personal projects, essays, or recommendation letters for this switch. Students on academic probation aren't considered at all, and every CODO decision is made "on a space-available basis," meaning your odds depend partly on how much capacity the department has that semester, not just your GPA alone.
Taken together, these two published, hard thresholds are a far more reliable signal of how competitive Purdue CS actually is than any unofficial "acceptance rate" estimate circulating online.
Getting Into Purdue CS as a Freshman vs. Transferring In Later
If you know you want CS, apply to it directly as your intended major on your first-year application — Purdue's admissions page lists Computer Science as a major you select during that initial application, housed in the College of Science, rather than something you apply to separately after enrollment. If you're admitted to Purdue in a different major and decide on CS later, expect the CODO path above: a real, published GPA bar, specific gateway coursework, and a space-available cap that adds genuine uncertainty even for students who clear the GPA threshold. Starting outside CS and switching in later is a meaningfully harder path than being admitted directly as a CS-intended freshman.
What Actually Matters for Your Purdue CS Application
Since Purdue doesn't isolate CS-specific criteria for freshman applicants, your best strategy is to exceed the university-wide admitted profile (3.70–4.00 GPA range, 1220–1480 SAT) rather than aim for some unpublished lower CS-specific bar — there's no evidence one exists for direct freshman admission. If there's any chance you'll apply to Purdue in a different major and try to switch into CS later, start planning for the CODO requirements from day one: CS 18000 and your required Calculus course are the two courses your entire internal-transfer chance rests on, so treat them as the highest-stakes courses of your first year, not just prerequisites to get through.

Purdue CS Acceptance Rate: FAQs
What is Purdue's Computer Science acceptance rate?
Purdue doesn't publish one. The university's overall acceptance rate was 43.4% for Fall 2025, but Computer Science isn't broken out separately for first-year applicants — the department's own FAQ confirms this.
How hard is it to get into Purdue CS?
Hard to quantify directly since there's no published CS-specific rate, but the university-wide admitted profile (3.70–4.00 GPA, 1220–1480 SAT middle 50%) is a reasonable proxy, and Purdue's published internal-transfer standards (3.00–3.5 GPA plus specific coursework) confirm real selectivity for students entering CS after their first year.
Can I switch into Computer Science after starting at Purdue in a different major?
Yes, through Purdue's CODO (Change of Major) process, which requires a minimum 3.00 cumulative GPA, completion of CS 18000 and an approved Calculus course with a B or higher, and is granted on a space-available basis — meaning even qualified applicants aren't guaranteed a spot if the department is at capacity.
What GPA do I need for Purdue CS?
For a direct freshman application, aim for Purdue's overall admitted middle-50% GPA range of 3.70–4.00, since no separate CS minimum is published. For switching into CS later via CODO, you need a minimum 3.00 cumulative GPA plus an A- or better in CS 18000, specifically.
Key Takeaway
There's no verified "Purdue CS acceptance rate" to find, no matter how specific the number some other site quotes you — Purdue simply doesn't publish one for first-year applicants. The real, published data points worth planning around are Purdue's overall 43.4% acceptance rate and admitted-student profile for your freshman application, and the hard 3.00–3.5 GPA thresholds plus specific coursework Purdue does publish for students trying to move into CS after starting elsewhere. If you're weighing Purdue CS against a program with a fundamentally different entry structure, see how UW-Madison handles Computer Science admission — a useful contrast, since it declares CS through a post-enrollment GPA gate rather than a direct freshman application.
