What is the UCSC SIP?

The University of California, Santa Cruz Science Internship Program (UCSC SIP) is a great opportunity for students who are passionate about science and eager to engage in research.

The program opens on June 22, 2025. From June 23 to August 8, 2025, you’ll participate in online research prep during the first week and work on in-person real projects for the next nine weeks. It all culminates on August 9, 2025, when you’ll present your findings and share everything you’ve learned.

The UCSC SIP got its start in 2009 with just three students from The Harker School, a private high school in Silicon Valley. It all began when UCSC Astronomy Professor Raja GuhaThakurta worked with these students on astronomy projects.

His vision was simple but powerful: by giving bright and motivated high school students the chance to dive into university-level research, he could help them grow and inspire them to pursue careers in research.

Since then, the program has grown tremendously. From its humble beginnings, it has welcomed 816 participants from 155 high schools. By 2019, ten years after it started, the program had expanded to include 180 interns working across 14 different departments, covering science, engineering, and social science topics.

For more insight into Professor GuhaThakurta’s inspiring approach, check out his TED Talk, Youth in Research: An Astronomer’s Perspective.

UCSC SIP research projects

Here are the subjects that research projects fall under:

It’s up to you to select the subject that most interests you!

As an intern, you’ll work on research projects that include assigned readings to help you dive deeper into your topic. Once your project is complete, you’ll present your findings in a final presentation.

Each project is carefully structured, starting with a title and details like your primary mentor, faculty advisor, project location, and the number of interns involved. You’ll also get a clear description of the project, a list of tasks you’ll be tackling, and any skills you’ll need before getting started. Plus, you’ll see what new skills you’ll pick up along the way.

UCSC SIP Acceptance Rate

The UCSC SIP is known for its competitiveness. While the exact acceptance rate isn’t publicly disclosed, it’s understood that the program receives a large number of applications each year, making admission quite selective.

Moreover, at the program, the ratio of girls to boys is 3:2, and about 60% of the students in high school who have participated in the program are female. Women are underrepresented in STEM, so it’s impressive that SIP’s ratio is 3:2.

When the UCSC SIP began, there were a few kids in private school, no public schools, and in 2014, it grew to 40% of students who attended public schools. Out of the 155 schools that students have attended while in SIP, two-thirds are public schools, and SIP is looking to increase that number.

UCSC SIP Application Deadline

How to Get into the UCSC SIP

If you’re a high school student dreaming of joining the UCSC SIP, here’s a step-by-step guide to help you stand out and boost your chances of getting in:

1. Do your research.

Take some time to explore the research projects conducted by past UCSC SIP participants. This will give you a better idea of the types of projects offered and help you decide which areas of science excite you the most. Understanding the program’s focus will also help you craft a stronger, more tailored application.

2. Show your passion for learning.

When filling out your application, make sure your essays and personal statement highlight your interest in the research area you want to pursue. Share specific examples of what drew you to the subject and how you’ve explored it on your own. The selection team looks for students who are genuinely motivated to learn and take on new challenges.

3. Sharpen your analytical thinking skills.

The program values students who can think critically and solve problems, so it’s a good idea to demonstrate these abilities. Reflect on experiences where you’ve applied analytical thinking—this could be in school projects, independent studies, or even real-life situations where you had to think things through logically.

4. Learn basic programming skills.

Many SIP research projects are computational, so having some experience with computer programming can give you an edge. If you’re new to programming, consider taking an introductory course online or at school to get a head start. Even a basic understanding of coding concepts will show your readiness to contribute to computational research.

5. Commit to the program’s timeline.

SIP prefers students who can commit to all nine weeks of the program. Make sure your summer schedule is clear, and mention your availability in your application to show that you’re ready to dedicate yourself fully to the experience.

6. Craft a standout application.

Your application should reflect who you are and what makes you a strong candidate. Double-check that you’ve included all the required materials—like your research area preferences, personal statement, transcript, and recommendation letters. Put effort into every part of the application to make sure it’s polished and professional.

Bonus tip: If you’re a returning SIP student, highlight your previous experience and what you gained from it. This can set you apart and show your dedication to continuing your learning journey.
