About Princeton LLP

The Laboratory Learning Program (LLP) is a free, full-time research program run by Princeton University’s Science Outreach office for local New Jersey high school students. Students join ongoing projects in Princeton science or engineering labs under faculty and research staff, usually for five to six weeks during office hours, commuting from home. Projects change each year depending on which faculty participate, each department sets the weeks and dates, and students submit a two-page research summary at the end.

The website says the program received over 3,000 applications in 2026 and that not all applicants are accepted; the number admitted and the acceptance rate are not published. LLP is free, pays no stipend, and provides no housing or transportation. Applicants must be US citizens in the United States attending a New Jersey high school in a district near Princeton; green cards and work permits are not accepted. The website also notes that admission to LLP implies no commitment regarding admission to Princeton.

LLP is not open to Irvine students. Irvine students who want commuter research in a university lab can look at UC Irvine’s Cancer Research Institute YSFP in this library.

How to Apply to Princeton LLP

  • LLP accepts only US citizens from local New Jersey school districts, so Irvine students are not eligible. For commuter research in a university lab, look at UC Irvine YSFP in this library, which takes Orange County high school students.
  • The application asks you to choose specific projects, and only those whose requirements you fully meet. The website repeatedly asks applicants not to contact faculty or departments directly.
  • The application window is about a month (February 15 to March 15 in 2026), and applications cannot be edited after submission. The website suggests drafting the short answers in a separate document first.
