## About this program

The **Research Science Institute (RSI)**, run by the **Center for Excellence in Education**, is one of the most academically rigorous and selective free summer science programs in the United States. The **RSI Alumni** program connects past participants who have completed the intensive RSI summer experience, which combines advanced STEM coursework with original, mentored research. Alumni engage with a community of peers who share a strong interest in science, technology, engineering, and mathematics, and who are often pursuing advanced studies and research opportunities.

The alumni network is especially valuable for high school students and recent graduates who are deeply committed to STEM and considering research-focused college and career paths. Through this community, alumni may gain access to:

- Informal mentoring and advice on research, internships, and academic pathways  
- Peer connections with students at top universities and research institutions  
- Opportunities to stay informed about STEM initiatives associated with CEE  

Because RSI is widely recognized for its rigor and selectivity, participation and subsequent involvement as an alumnus can demonstrate sustained commitment to high-level scientific inquiry on college applications. Students who thrive in challenging, research-oriented environments and who are motivated to continue their scientific growth beyond a single summer are best suited to engage with the RSI Alumni community.
