From the outset of their time at Princeton, students are encouraged and challenged to develop their scholarly interests and to evolve as independent thinkers.

The culmination of this process is the senior thesis, which provides a unique opportunity for students to pursue original research and scholarship in a field of their choosing. At Princeton, every senior writes a thesis or, in the case of some engineering departments, undertakes a substantial independent project.

Integral to the senior thesis process is the opportunity to work one-on-one with a faculty member who guides the development of the project. Thesis writers and advisers agree that the most valuable outcome of the senior thesis is the chance for students to enhance skills that are the foundation of future success, including creativity, intellectual engagement, mental discipline and the ability to meet new challenges.

Many students develop projects from ideas sparked in the classes they’ve taken; others fashion their topics on the basis of long-standing personal passions. Most thesis writers encounter the intellectual twists and turns of any good research project, where the questions emerge as they proceed, often taking them in unexpected directions.

Planning for the senior thesis starts in earnest in the junior year, when students complete a significant research project known as the junior paper. Students who plan ahead can make good use of the University's considerable resources, such as receiving University funds to do research in the United States or abroad. Other students use summer internships as a launching pad for their thesis. For some science and engineering projects, students stay on campus the summer before their senior year to get a head start on lab work.

Writing a thesis encourages the self-confidence and high ambitions that come from mastering a difficult challenge. It fosters the development of specific skills and habits of mind that augur well for future success. No wonder generations of graduates look back on the senior thesis as the most valuable academic component of their Princeton experience.
