Summer Internship Program (SIP)

We are not welcoming summer interns or special volunteers in 2025. We look forward to welcoming applications for Summer 2026.

About SIP 

The National Cancer Institute offers a summer research internship for students interested in exploring careers in all areas of cancer research, including basic, clinical, and translational research, epidemiology, biostatistics, genetics/genomics, and behavioral research. The program is open to high school, college, postbaccalaureate masters-level students, and graduate students, including medical and dental students. Successful applicants join the NCI for at least eight weeks between May and September and work under the supervision of an NCI researcher. This program is part of the NIH Summer Internship Program (SIP) in Biomedical Research. 

The 2025 NIH Summer Internship Program will be IN-PERSON (i.e., on-campus). If you are a college student and interested in completing a virtual internship, you must apply to the Virtual Summer Opportunities to Advance Research (V-SOAR) program. No other virtual internships will be considered

Summer internships at the NCI and NIH are paid internships; summer interns are paid based on their academic level.

Interns are encouraged to attend lectures offered under the NIH Summer Seminar Series, participate in group meetings and seminars, attend formal NIH lectures and symposia, and participate in the NIH Summer Research Program Poster Day. 

NCI also offers a curriculum available for all summer interns that represents the diverse research areas within the Institute.

How to Apply

Eligibility

To apply to the NIH Summer Internship, you must be a U.S. citizen or permanent resident and at least 18 years of age by the start of the summer. Additionally, you must be:

  • enrolled at least half-time in high school (seniors only) OR
  • enrolled at least half time in an accredited community college, college or university as an undergraduate, graduate, or professional school student OR
  • accepted into an accredited graduate program for the fall semester with the expectation of attending at least full-time. 

Students with disabilities; students from racial and ethnic groups that have been shown by the NSF to be underrepresented in health-related sciences on a national basis (Blacks or African Americans, Hispanics or Latinos, American Indians or Native Americans, and Native Hawaiians and other Pacific Islanders); students who identify as LGBTQ; students who are Pell-grant eligible; and others disadvantaged by circumstances that have negatively impacted their educational opportunities, including recent natural disasters, are encouraged to apply.

Applicants with a family member working at the NCI should know the strict nepotism policy, which may limit their ability to work within specific research groups.

There are additional eligibility requirements that vary by program. Please be sure to check the requirements for the program you are interested in. Applicants can find additional information on the NIH Summer Internship Program website.

Applications are reviewed on a rolling basis and are completed by April 1st. Please note that there is no centralized selection process. Individual scientists select their own summer interns and provide their own funding. Successful candidates will be informed by their PI and on-boarding paperwork will be done by the individual research group. Additional paperwork for selected interns includes:

  • Official high-school, college, or graduate/professional school transcripts 
  • Proof of U.S. citizenship or permanent resident status 
  • Proof of health insurance

Note: There will be a lot of paperwork, so please be sure to check your email regularly.

All research training offers are contingent on your ability to successfully pass a federal background check. You must pass to be granted access to NIH facilities and systems.
