National Institutes of Health Summer Internship Program (SIP)
Research & internships · National Institutes of Health · Bethesda, MD and other NIH campuses
Summer research internships in NIH labs. High school seniors can apply if they meet the age rule.
Our take
Paid research in an NIH lab. The separate high school track (HS-SIP) was folded into the main program, so it is now for graduating seniors who are 18 by the start, with a narrow exception for 17-year-olds who live near a campus. Check the age rule before you apply.
“Helps an application” is our read on how much an admissions reader is likely to weigh it: Strong means getting in or placing is a real achievement, Solid means it shows real interest and effort, and Light usually means most students who apply and pay can attend. It’s our opinion, not a ranking from any college, and a light one can still be a great summer.
