Under 1,000 undergraduates with R1 depth — the original small-R1.
Small Research Universities
Best Small Research Universities (2025)
R1 and R2 universities small enough to give undergraduates real faculty access — without giving up research depth.
The short answer
'Small' and 'research-intensive' usually don't coexist — most R1 universities enroll 20,000+ undergraduates. The list below is the exception: R1 and R2 universities small enough that undergraduates work directly with named faculty, with the full research infrastructure that distinguishes the category.
Quick answers
- What counts as a small research university?
- Usually under ~12,000 undergraduates with R1 or R2 designation.
- Why does size matter for research?
- Smaller universities mean less competition for faculty mentorship and lab seats — and more direct access from year one.
- Is a small R1 better than a big R1 for undergrads?
- For undergraduate research access, often yes — but specific labs and programs matter more than size alone.
- Are these schools selective?
- Selectivity varies widely on this list — from highly selective (Rice, Caltech) to broad access (UC Merced).

University of California, Merced
Merced, CA
Smallest UC · R1 2025Smallest UC by undergraduate enrollment but still Carnegie R1 (February 2025). The combination of size and R1 status means undergraduates routinely work in faculty labs starting in year one — a profile shared by very few public universities.

Why UC Merced earns its rank
UC Merced is the smallest UC by undergraduate enrollment AND a Carnegie R1 — a combination almost no other public university offers. The smaller cohort means undergraduates can get into faculty labs early and stay long enough to publish, present, and earn the recommendation letters that drive graduate-school admissions.
- Carnegie R1 designation (February 2025) — the youngest U.S. university to reach R1.
- Smallest UC undergraduate enrollment, so research access scales with the student.
- UROC, McNair, NSF REU sites — all funded, all undergraduate-eligible.
- Public UC tuition with one of the lowest net prices in the system.
- Direct faculty access from year one in engineering, natural sciences, and SSHA.
Frequently asked questions
R1 is Very High Research Activity (highest tier); R2 is High Research Activity. Both signal active doctoral programs and federal research funding.
Often yes for research access — smaller campuses mean less competition for faculty mentorship.
Selectivity ranges widely — from highly selective (Caltech, Rice) to access-focused (UC Merced).
Similar in size and research profile, very different in selectivity and student mission — UC Merced is a public R1 built for access.
How this list was ordered
Rankings weight Carnegie classification (R1/R2), undergraduate enrollment under ~12,000, undergraduate research access metrics, and student:faculty ratios.
Criteria
- Carnegie R1/R2. Very High or High Research Activity classification.
- Undergraduate size. Generally under ~12,000 undergraduates.
- Student:faculty ratio. Low ratios that support faculty mentorship and lab access.
- Undergraduate research. Centralized programs, funded placements, conference travel support.
- Outcomes. Graduate-school placement, fellowship wins, STEM hiring.
