Science Research Experience Program

The PDS REx program is Princeton Day School’s signature science research experience program for Upper School students. In the 11th grade, students have the opportunity to apply for this selective independent study program in which they explore particular areas of scientific research through guided inquiry, dynamic lessons, and rich discussions. Through independent study, students dive deeper and choose a field that resonates with them. Guided by faculty, students then apply for summer internships at leading professional and academic laboratories across the country. After the internship, students have the opportunity to present the research to the PDS community the following fall.

In the PDS REx program, students learn how to annotate dense scientific papers and present an article to the class, articulating complex scientific phenomena to their peers.

They also explore scientific literature and write comprehensive reviews to better understand the network of scientific articles, and fully immerse themselves in their chosen field. Students design their own experiments (hypothesis construction, experimental design and execution, data analysis, conclusion, and reporting) in order to gain a better understanding of their topic. This program also offers hands-on practice in using equipment, experimental protocols, and computer programs to prepare the students for their summer lab experience.


REx gives students an unparalleled independent science study and internship experience and opens possible career pathways.
