Caltech Undergraduate Admissions: A Complete Guide to Submitting Research Papers and Publications
Caltech is widely recognized as one of the most rigorous and research-intensive institutions in the United States. Because of its strong STEM identity, many families assume that meaningful research experience—or even a published paper—is required for admission. Fortunately, this is not the case.
While Caltech values intellectual curiosity and academic depth, research is not a mandatory component of the application. Still, if your student does have research experience, understanding Caltech’s official submission standards is crucial. This guide provides a clear breakdown of Caltech’s policies, the difference between Research Papers and the STEM Portfolio, the four mandatory components required for formal research submission, and common pitfalls families should avoid.
1. Research Experience Is Not Required
Caltech classifies research submissions as Supplemental Materials, not as core application requirements. Recent data shows that only about 35% of admitted students submitted a research paper or publication.
This means your student can absolutely present a strong, competitive application without formal research. High-level STEM coursework, strong recommendations, academic passion, and self-driven projects remain equally powerful components.
That said, if a student does have legitimate research experience, submitting it correctly can strengthen the application—provided it meets Caltech’s strict criteria.
2. Two Submission Categories: Research Papers vs. STEM Portfolio
Caltech divides research-related submissions into two distinct categories:
A. Research Papers & Publications
To qualify for this category, the student’s work must meet all three of the following conditions:
- The research was conducted in a university lab or an affiliated institutional research setting.
- The student worked under direct supervision of a PI (Principal Investigator), a Ph.D. researcher, or another qualified adult researcher.
- The resulting paper is published, submitted, or in preparation for submission.
If all three criteria are met, Caltech recognizes the work as formal research.
B. STEM Portfolio
If the submission does not meet any one of the three criteria above—or if it is missing any part of Caltech’s mandatory four components (explained later)—it must be submitted as a STEM Portfolio instead.
Examples of activities appropriate for the STEM Portfolio include:
- Summer research program participation
- IB Extended Essay
- Independent projects completed without a mentor
- AP Research course papers
- Personal inventions, designs, or experimental projects
In reality, most high school students fall into the STEM Portfolio category, and this is completely acceptable.
3. The Four Mandatory Components for Research Paper Submission
Students submitting formal Research Papers & Publications must include all four of the following items. Missing even one automatically reclassifies the submission as a STEM Portfolio.
1) Full Research Paper (Preferred) or Abstract/Poster
Caltech strongly prefers the full paper.
If unavailable, an abstract or research poster is acceptable.
For embargoed submissions, the supervising professor must explain the embargo in their recommendation letter.
2) Supervisor Recommendation Letter
This must be written by an adult who directly oversaw the student’s research and can accurately evaluate their work.
Eligible recommenders include:
- PI or faculty researcher
- Ph.D.-level postdoctoral researcher or mentor
- Adult co-author
- Research program administrator
The letter should include:
- The student’s specific research responsibilities
- Technical skills and contribution level
- Collaboration and work ethic
- Connection to the submitted paper
Submission process:
After the student submits the Caltech application, they will access the Beaver Breakroom portal, enter the recommender’s email, and Caltech will send the recommender an upload link.
3) Research Description Form
Every submitted paper must have its own description form.
This form helps Caltech understand the student’s exact role and level of independence.
Common questions include:
- How did the student secure this research opportunity?
- What were their responsibilities and contributions?
- Duration of participation
- Research objectives
- Current paper status (published/submitted/in preparation)
4) Viva Exam
To verify the student’s understanding of the work, Caltech requires a short Viva Exam.
It is accessed through the Beaver Breakroom portal.
The format is straightforward, but students must clearly explain the research they participated in—methodology, purpose, findings, and personal contributions.
Many students struggle with this step, making preparation essential.
4. Additional Important Points Families Should Know
A. Students may submit multiple research activities
If multiple papers exist, Caltech allows all of them.
For work completed under the same mentor or in the same lab, only one recommendation letter is required.
B. No penalty if the research topic does not match the intended major
A student interested in biology can submit a physics research paper with no issue.
Caltech values intellectual depth above perfect alignment.
C. No disadvantage for applicants without research
Caltech openly states that research is optional.
Students are equally evaluated on:
- Advanced STEM coursework
- Olympiads and competitions
- Independent or self-driven STEM projects
- Strength of recommendations
- Intellectual curiosity and analytical thinking
One of the most common misconceptions parents have is:
“You must have research to get into Caltech.”
This is simply untrue.
Caltech prioritizes a student’s potential, passion for STEM, and genuine academic commitment.
5. Final Advice for Families Preparing for Caltech
Because Caltech’s criteria for formal research submissions are strict, most students will be better served by submitting their work as a STEM Portfolio rather than trying to force it into the Research Paper category.
- Short-term camps or brief summer projects rarely meet all four required components.
- Students with true research experience must carefully ensure all required documents are prepared.
- Viva Exam preparation is especially important—students should practice explaining their research in clear, logical terms.
- Above all, Caltech values authentic curiosity, creativity, and intellectual courage.
Encourage your student to highlight their strengths honestly and confidently.
A thoughtful, well-constructed application always carries more weight than a checklist of accomplishments.
