Deciding whether to apply to the UCSC SIP usually comes down to more than curiosity about research. Families want to know what a seat actually costs, how selective admission really is, and whether the time and money are worth it before an application goes in.
UC Santa Cruz’s own selection guidance offers a useful clue about what the program rewards. According to SIP, reviewers weigh a student’s interest in the subject area they may be matched to, their motivation to learn new material, and their capacity for analytical thinking, and many available projects are computational in nature. The program itself is built around authentic, open-ended research in which results and methods may change as the project develops.
UCSC SIP recently rebranded its acronym to the the Scholar Immersion Program, so students searching for information about the program may find guides that reference it’s previous name, the Science Internship Program. This guide walks through what SIP costs, how competitive admission is, what the application requires, and whether it’s worth pursuing for summer 2027.
The UCSC Scholar Immersion Program places high school students directly into active research groups at the University of California, Santa Cruz, working with faculty-supervised teams that commonly include graduate students, PhD students, and postdoctoral researchers. Rather than following a pre-set research curriculum, students contribute to active, open-ended UCSC research projects that were not created solely for high school participants.
In August 2026, UCSC renamed the program from the Science Internship Program to the Scholar Immersion Program. The university kept the familiar SIP acronym, and many prospective applicants still know the program by its original name, which is why this guide uses both.
SIP itself was founded in 2009 by UC Santa Cruz astronomy professor Raja GuhaThakurta. As of 2025, SIP had served roughly 2,400 interns from around the world.
Students join active UCSC research groups and work on open-ended projects rather than assignments built solely for high school students. Recent cohorts have spanned a wide range of disciplines, from astronomy and biomolecular engineering to computer science, economics, environmental studies, anthropology, linguistics, literature, philosophy, and other social sciences, with some projects also examining data governance, according to SIP’s published project listings.
The eight-week program begins with one week of online research preparation, followed by seven weeks of in-person research at UC Santa Cruz. The program culminates in a Final Presentation Day where interns present their work. The specific projects offered change from year to year depending on each mentor’s ongoing research.
Interns gain practical experience with research methods, research design, data collection, and data analysis as they work alongside university research teams. Depending on the project, that can include archival research, reviewing academic literature and scientific literature, or reading academic papers.
Many SIP projects are computational, and UCSC notes that prior programming experience is desirable for those placements, although it is not a general requirement for admission. For example, a 2026 astronomy project had interns use Python and Jupyter notebooks to analyze James Webb Space Telescope data from the JADES survey, while a genomics project examined how repetitive regions of the genome affect mapping and variant calling. Students interested in data-heavy research may also want to explore our roundup of computer science research programs for additional options.
UCSC does not publish an official acceptance rate for the Science Internship Program, so any specific percentage circulating online should be read with caution. Rather than a number, UCSC points to what it’s actually judging: how genuinely a student wants to dig into the subject they’d be placed in, how eager they are to pick up new material, and how well they reason through open-ended problems. Students who’ve done SIP before, or who can be there for the whole eight weeks, may get a slight edge.
SIP says it receives a few thousand applications and cannot accept every qualified applicant. Without an official rate, applicants are better served treating SIP as a competitive program than anchoring to an unverified statistic.
SIP is university-driven: students are placed into active UCSC research projects led by university researchers, giving them hands on research experience rather than a research exercise created specifically for high school students. Our guide to summer research opportunities breaks down what to look for when comparing research structure, mentorship, academic oversight, and student responsibilities across different summer programs.
That structure is valuable, but the university name is only part of the experience. How much a student gets from SIP also depends on how seriously they engage with the project, collaborate with their research group, and respond when the work takes an unexpected direction.
Applicants apply directly through UCSC’s own portal. SIP has no general prerequisite-course requirement, although individual projects may require specific coursework, and the program considers strong high school grades as part of the application. The table below outlines what a complete SIP application includes.
SIP has a firm policy against unauthorized middlemen: outside organizations or individuals may not charge unauthorized application or placement fees on behalf of UCSC SIP. UCSC strongly encourages students to apply directly through its own application portal. A missing academic reference by the reference deadline makes the application incomplete, so it’s worth confirming that the reference is on file before the deadline.
The dates below reflect the 2027 schedule currently listed for SIP. The program calendar for the in-person weeks has not been finalized yet, so those rows are estimated from SIP’s typical schedule and will be firmed up when UCSC posts full 2027 details.
Applicants who receive an offer must accept it and submit a non-refundable deposit within a week. The remaining balance is due by a separate registration and payment deadline established by SIP, rather than necessarily one week after the offer.
UCSC has not yet released 2027 tuition or housing costs for the Scholar Immersion Program. The university has said full 2027 pricing will be posted on the program’s website by December 2026, so any specific dollar figures published elsewhere before then reflect an earlier cycle and shouldn’t be treated as current.
What is confirmed for 2027 is the $68 application fee, separate from program tuition. Once tuition is announced, costs are typically broken into a base program fee, an on-campus housing charge for the seven in-person weeks, and an optional weekly shuttle for students who choose to commute rather than stay on campus. Admitted students also generally pay a non-refundable deposit to hold their place, due within a week of an offer. In the most recent published cycle, that initial deposit was waived for students requesting need-based scholarships.
Yes. SIP sets aside partial and full need-based aid for families who need it. In the most recent published cycle, qualifying students received packages covering 25%, 50%, 75%, or 100% of program fees, with aid also available for transportation, room, and board expenses associated with attending SIP.
Admission decisions come first, and scholarship requests are considered afterward, so financial need has no bearing on admission. Families seeking aid submit their scholarship request and supporting information after receiving an offer, as part of the acceptance process.
SIP isn’t the only university-driven research option for high schoolers, and it’s worth comparing it against other STEM programs in California and other college-based research programs for high school students before committing to one application.
The program runs about eight weeks total, typically mid-June to early August. The first week happens remotely, as students complete online research-preparation work, and the remaining seven weeks are spent working in person at UC Santa Cruz. SIP may give preference to applicants who can commit full-time for all eight weeks, although individual research schedules are arranged between interns and mentors.
Yes. On-campus housing is offered for the in-person program. General campus housing covers Sunday through Thursday nights during the seven research weeks, while students from outside the Bay Area may have access to a special seven-day housing option that also covers weekends. Students who commute don’t have to live on campus at all. SIP offers a shuttle option for weekly commuters, or students can arrange their own transportation to campus.
Yes, out-of-state students can apply. International eligibility is more complicated and depends on citizenship, immigration status, and current U.S. entry restrictions. Recent SIP applicant materials have listed U.S. citizens, green card holders and other U.S. residents, Canadian citizens, certain F-1 or J-1 visa holders, citizens or nationals of Visa Waiver Program countries, and certain B-1/B-2 visa holders as potentially eligible. Because U.S. travel restrictions can change, international applicants should check SIP’s current guidance for their application year rather than relying on an older country list.
Students who meet the eligibility requirements and live outside the area can use SIP’s campus housing options or stay with a local guardian rather than having to arrange independent off-campus housing.
No prior research experience is required. SIP’s own guidance points to interest in the subject area, motivation to learn, and analytical thinking as what it looks for in applicants, and separately notes that some prior programming experience is desirable for students placed in computational projects. UCSC also says there are no general prerequisite-course requirements, although individual projects may require specific coursework.
Offers are made on a rolling basis starting April 9, 2027. Students who receive an offer have within one week to accept it and generally submit a non-refundable deposit to hold their place, so it’s worth deciding in advance how quickly a family can respond. In the most recent published cycle, the initial deposit was waived for students requesting need-based scholarships.
SIP asks a lot of the students it admits: a full eight-week commitment, a willingness to work through an open ended research project, and the patience to work within an existing UCSC research group rather than on a project designed around the student. That structure, not a headline acceptance rate, is what makes the program worth taking seriously.
Students weighing SIP against other options have a reasonable amount of research to do before applying, from comparing costs once UCSC releases them to reviewing the available research areas and, once published, that summer’s project list for genuine fit. Families exploring the broader landscape of research programs for California high school students will find SIP is one option among several worth comparing closely.
