Admissions FAQ

When is the application deadline?

December 1, for enrollment the following fall. The program admits for fall entry only — there is no spring or summer entry. Your file needs to be complete by that date, so give your recommenders and your testing services enough runway.

How do I apply, and is there a separate department application?

You apply through the Purdue Graduate School's online application system, SLATE. That is the only application needed; the Department of Psychological Sciences does not have a separate form of its own. You may apply to up to three of the department's doctoral programs.

Start from the program's page in the College of Health and Human Sciences, which links through to the application.

What does the application have to include?

Transcripts, letters of recommendation, an academic statement of purpose, a personal history statement, GRE scores, and a resume or curriculum vitae.

You can upload student copies of your transcripts to the application to begin with — they need to be institutional copies rather than screenshots of a student portal. Official transcripts are not required until after you have been admitted. Your recommenders are emailed a link automatically once you complete the recommendation section of the application.

We pay close attention to the statement of interest, looking for alignment between your research interests and a faculty member's. That is the part of the application most worth your time.

Is the GRE required?

Yes. The GRE General Test is required for admission to the I-O psychology program. (It is optional or not required for some of the department's other programs, so advice you read about Purdue psychology generally may not apply here.) The Psychology subject test is not required.

When you send scores, Purdue's institution code is 1631 and Psychological Sciences' general psychology code is 2016. You do not have to wait until your application is submitted to have scores sent.

We look for strong verbal and quantitative scores, and we pay attention to analytic writing, because research writing matters a great deal in this program.

Can I apply for a master's degree?

No. We offer a Ph.D. only and do not offer a terminal master's degree, so on the application you must choose Doctoral Degree as your enrollment objective. Students do earn a master's along the way by completing a thesis, but it is a milestone within the doctorate rather than a program you can apply to.

Most students enter with a bachelor's degree; some enter with a master's. Students arriving with a thesis-based master's from another institution can ask to have the Purdue thesis requirement waived — see the curriculum page.

Do I have to name a faculty member?

Yes — you must list one or more program faculty on your application. Students are admitted to work with a specific major professor, so this is not a formality. Which faculty are admitting changes from cycle to cycle, and the current list is on our people page.

Should I email faculty before I apply?

Yes. Prospective applicants are encouraged to contact the faculty member whose research interests match their own, and their email addresses are on the people page. A short, specific message about your interests and why they align with theirs is worth more than a long one.

There is more on this in our faculty advice section, including what our own faculty suggest reading and how they think about fit.

Do I need to apply separately for funding?

No. If you are admitted you are automatically considered for assistantship funding, and automatically considered for any Graduate School fellowships you qualify for. There is nothing extra to fill in.

Every admitted student is admitted with funding. Students typically work as a graduate teaching assistant for 20 hours per week during the academic year, receiving a nine-month stipend and a tuition waiver, and all graduate students have guaranteed funding for five years provided they are making good progress toward the Ph.D. Summer funding may be available through a teaching or research assistantship. See admissions and funding for the other sources of support.

How much is the application fee, and can it be waived?

The application fee is $60 for domestic applicants and $75 for international applicants. Waivers are available through certain recruitment programs, and can also be requested from the Graduate School on grounds of financial hardship by writing to gradinfo@purdue.edu. If the fee is a barrier, ask — do not let it stop you applying.

What are the English proficiency requirements?

Applicants whose native language is not English must demonstrate English proficiency. For the TOEFL internet-based test taken before 21 January 2026, the minimum overall score is 80, with section minimums of 19 reading, 14 listening, 14 speaking, and 18 writing. For tests taken on or after 21 January 2026, under the revised scale, the minimum overall score is 4, with 4 reading, 3.5 listening, 3.5 speaking, and 4 writing.

Requirements are set by the Graduate School rather than by this program, and other tests are accepted; check the Graduate School's requirements page for this program for the authoritative current list.

What GPA do I need?

The Graduate School's recommended minimum is a 3.0/4.0 undergraduate cumulative GPA. In practice, admitted students usually have GPAs between 3.5 and 4.0, and the average undergraduate GPA of our current students is 3.64.

A lower overall GPA is not automatically disqualifying — a change of major or other circumstances can explain it, and we read applications as a whole. Research experience carries real weight: we are particularly interested in applicants with undergraduate or post-undergraduate research experience, and we view an MA or MS in I-O psychology or an allied field favorably.

How long does the Ph.D. take?

Four to six years. The curriculum page sets out the coursework and the milestones — the master's thesis, the preliminary examination, and the dissertation — that fill them.

Is this the same as Purdue Global's I-O program?

No, and this catches people out. This program is part of Purdue University's Department of Psychological Sciences in West Lafayette, Indiana. It is not affiliated with the Purdue Global I-O psychology program, which is a separate institution with separate admissions.

Who do I ask if my question is not here?

For questions about the application itself, the Department of Psychological Sciences graduate program coordinator is khaskett@purdue.edu. For questions about a faculty member's research or whether they are taking students, write to them directly — addresses are on the people page. For anything about student life in the program, PAGSIP can be reached at PAGSIP@purdue.edu. Our contact page lists all of these together, along with the department's address and main line.

Deadlines, fees and test requirements are set by the Purdue Graduate School and the Department of Psychological Sciences, and they do change. The Graduate School's requirements page and the department's graduate FAQs are authoritative; this page summarizes them for convenience.
