Caltech’s Summer Research Connection (SRC) is a selective summer research program that places a limited number of Pasadena Unified School District (PUSD) high school students into active Caltech research labs for approximately six weeks. Unlike broad, tuition-based STEM camps, the Caltech Summer Research Connection is designed as an outreach and equity-focused initiative that emphasizes authentic research participation over classroom instruction.
If you are a PUSD student with strong preparation in math or science and are willing to treat your summer like a full-time research commitment, the Caltech Summer Research Connection can provide unusually early exposure to how academic research actually functions.
What is the Caltech Summer Research Connection for High School Students?
SRC is a six‑week summer research program run by Caltech’s Center for Teaching, Learning, and Outreach in partnership with the Pasadena Unified School District for K–12 science teachers and PUSD high school students.
You are embedded in an ongoing research group (e.g., physics, computing, biology, environmental science), work on a defined sub‑project under the supervision of a faculty or postdoctoral mentor, and present what you did at the end (poster, talk, or written report, depending on the lab and year).
Because SRC is limited to one district, it functions less like a national pre-college competition and more like a structured pipeline from PUSD into high‑level STEM research. If you are not enrolled in a PUSD high school, you are not eligible for SRC and should consider other Caltech outreach initiatives or national programs, such as SSP, RSI, or university research camps.
What will you do as a participant?
For eligible students, SRC is often compared with STEM camps or large pre-college programs. Students tend to choose SRC because:
- You engage in domain‑specific, mentor‑guided research rather than pre‑designed classroom labs, which is closer to what undergraduates do in SURF‑style projects at Caltech.
- Your work is embedded in real projects, where mentors and graduate students use the data, code, or analysis you help produce, and your task connects to a larger research question.
- It is designed as an equity‑oriented partnership for a single public district, meaning you are not competing with thousands of national or international applicants. Instead, you compete with peers who have similar local school contexts.
Program Overview: Logistics at a Glance
The following reflects the typical program structure, noting where details may vary by year:
Audience: PUSD high school students and participating K–12 science teachers, working together in research groups on campus
Location: Caltech campus, Pasadena, CA (non-residential; students commute)
Duration: Six continuous weeks in summer | Full‑time weekday commitment
Dates: Typically June through late July or early August | Application generally opens in January and closes by late March, with decisions in early April
Cost/Funding: Implemented as an outreach program with no standard published tuition | Funding flows through Caltech’s outreach and district partnerships
Eligibility: Enrolled in a Pasadena Unified School District high school | Generally rising juniors or seniors with strong STEM preparation and teacher recommendations | Interest in STEM and willingness to commit to full‑time lab work for all six weeks
Application Components: Online application with short essays on your STEM background, interests, and goals (exact prompts vary by year) | Transcript and one or more teacher recommendations, often from science or math teachers.
Note: You should treat the application as you would an early college‑style research application: concrete about courses, projects, and why you want to do research.
What You Actually Do Day to Day
Your project will depend entirely on the lab you join, but typical themes include robotics, computational biology, planetary science, materials science, and data-intensive fields such as astrophysics or environmental modeling. You will usually work as part of a team that includes one or more high school students, a participating science teacher, graduate students or postdoctoral researchers, and a faculty mentor.
Common activities include:
- Lab meetings: discussing experimental design, parsing recent results, and planning next steps.
- Bench or computational work: running experiments, collecting data, troubleshooting code, or iterating on an analysis pipeline.
- End‑of‑program products: a poster or oral presentation, often with an emphasis on explaining methods and limitations.
Caltech outreach reports note that students often find this environment challenging because progress is incremental and uncertainty is common, an intentional feature of authentic research. You can read more about it here.
Skills You’ll Develop
The primary value of SRC lies in the research habits you develop rather than the final output itself.
Research and Analytical Skills
Students typically build experience in:
- Experimental design fundamentals: how to define a precise research question, identify variables, and build a feasible protocol under time and resource constraints.
- Data collection discipline: keeping consistent lab notebooks, logging conditions, and iterating accordingly.
- Literature engagement: searching for, reading, and summarizing scientific papers that match your project, then mapping your work onto existing results.
- Quantitative reasoning: using statistics or simple modeling to interpret noisy data.
Many Caltech Connection participants who work in structurally similar, mentored research setups report increased confidence in “conducting literature searches, critically analyzing scientific articles, and creating effective poster presentations.”
Technical and Computational Tools
Tools vary by lab, but commonly reported skill areas include:
Programming:
- Python or MATLAB for numerical work, data cleaning, and visualization.
- Basic version control (often Git) and working with Jupyter notebooks or similar environments for reproducible analysis.
Lab Instrumentation:
- For experimental physics or engineering: oscilloscopes, microcontrollers, motion stages, or custom apparatus control software.
- For biology/chemistry: micropipettes, spectrophotometers, microscopes, and the associated calibration and safety procedures.
Data Pipelines:
- Importing raw data from instruments, cleaning it, and producing publication‑style figures.
Communication and Professional Skills
SRC also emphasizes communication within a research setting:
- Writing concise abstracts and figure captions that describe what was done.
- Presenting findings to mentors and peers, explaining complex concepts without losing technical accuracy.
- Responding to technical feedback and learning how responsibilities are distributed within a lab.
Caltech reports that students often present their work at program-wide seminars or culminating events.
Student Experiences and Feedback
Student reflections on Caltech’s Summer Research Connection are broadly positive and emphasise how academically substantial the experience feels. Drawing on Caltech’s outreach pages, individual lab write‑ups, outcome reports from Caltech Connection, and public videos, students consistently describe SRC as a “really positive experience” that “helped prepare me for the future” and left them feeling “ahead of the game” in later coursework and research.
They often credit the program with clarifying or even reshaping their long‑term paths, including feeling newly confident about transferring to research‑intensive universities and pursuing graduate study after seeing themselves function in a real lab environment. Participants also repeatedly highlight strong mentorship , describing thoughtful feedback from faculty and graduate students, a supportive environment for growth, and the feeling of being treated as junior collaborators rather than passive observers.
Is This Program the Right Choice for You?
Because SRC is highly context‑specific, “worth it” depends on fit rather than reputation.
SRC is likely worth it if:
- You are a rising junior or senior in a PUSD high school with strong math/science coursework and genuine curiosity about research.
- You can commit to six full‑time weeks and are okay with treating the summer like an unpaid or modestly funded job.
- You want to understand whether you actually enjoy the day‑to‑day of research (debugging experiments, fixing broken code, reading dense papers) before college.
SRC may not be the best fit if:
- You are mainly looking for broad exposure to multiple STEM topics rather than depth in one research problem.
- You are constrained by transportation or other summer obligations that make a full‑time, in‑person commitment difficult.
- You want a program with national name recognition for admissions committees outside of California over skill development.
For a PUSD student serious about STEM, SRC is one of the few opportunities to work in a globally ranked research institution while still in high school, build domain‑specific technical skills, and collect credible evidence (letters, presentations, concrete projects) that you can function in a lab. If that matches your goals and you can realistically commit the time, it is very likely to be worth it.
