Purdue Supplemental Essays 2026–27: Prompts & Tips

Purdue University requires two supplemental essays of every applicant, totaling roughly 500 words. This guide covers the prompts every applicant answers. Purdue University may ask additional essays of applicants to particular programs or colleges, and your exact workload will depend on your chosen field of study.

How will opportunities at Purdue support your interests, both in and out of the classroom? (Respond in 250 words or fewer.)

What this prompt is really asking: This is Purdue’s version of the classic “Why Us” essay, but it specifically demands balance. You need to connect your academic ambitions to campus resources while showing how you will engage with the student body outside the lecture hall.

A strong approach:

• Split the focus: Aim to dedicate roughly equal space to academic opportunities and extracurricular involvement. The phrase "both in and out" is a strict structural requirement.
• Identify specific academic resources: Look beyond the general prestige of the university. Name the exact undergraduate research labs, specific courses, or academic centers that align with your intellectual interests.
• Find your social fit: Whether it is a professional society, an intramural sport, or a cultural club, show how you will contribute to campus life. Purdue wants to see that you will be an active member of their community.
• Connect past to future: Briefly mention what you already do, then show how a specific Purdue opportunity is the natural next step for that interest.

Most common mistakes:

• Listing without explaining: Dropping five club names without explaining why you want to join them wastes word count and fails to show genuine interest.
• Ignoring the outside half: Focusing entirely on your major and research will make your response feel incomplete to an admissions reader looking for community contributors.

Briefly discuss your reasons for choosing your major and your interest in studying at this campus location (Indianapolis or West Lafayette). (Respond in 250 words or fewer.)

What this prompt is really asking: Purdue wants to know the origin story of your academic focus and why their specific campus environment suits your goals. It is a combined major-choice and location-preference question testing your academic maturity.

A strong approach:

• Pinpoint the spark: Share a concrete anecdote about solving a problem, volunteering, or discovering a passion. This is much stronger than a general statement about liking math or science.
• Address the campus location: Clearly state whether you are aiming for West Lafayette or Indianapolis and explain why. Highlight factors like the campus culture, proximity to specific industries, or the scale of the university environment.
• Connect major to location: If possible, show how your chosen location enhances your study of the major. An applicant wanting to study motorsport engineering will find clear advantages at the Indianapolis location.

Most common mistakes:

• Skipping the location question: Many applicants get so wrapped up in explaining their major that they forget to discuss their campus preference entirely.
• Relying on childhood clichés: Tracing an engineering major back to playing with building blocks is a worn path. Focus on recent high school experiences that solidified your choice.

Alternate major essay

If you indicate on your application that you want to be considered for an alternative major, you will be asked to explain that choice.

Briefly discuss your reasons for pursuing the alternate major and campus location (Indianapolis or West Lafayette) you have selected. (Respond in 250 words or fewer.)

What this prompt is really asking: This is your chance to show that your secondary choice is a genuine academic interest rather than a random backup option.

A strong approach:

• Find the thematic link: Connect your alternate major to your primary interest. If your first choice is mechanical engineering and your second is physics, explain how both satisfy your curiosity about physical systems.
• Justify the location: Briefly reiterate or introduce why the campus location for this alternate major makes sense for your goals.
• Keep it positive: Treat this major with the same enthusiasm as your primary choice. Avoid framing it as a disappointment or a fallback plan.

Most common mistakes:

• Copy-pasting your first essay: Do not just reuse your primary essay with a few words swapped out. The admissions reader will read them back to back.
• Choosing an unrelated alternate: Picking a completely disconnected major without explanation can make your academic goals look unfocused.
