CITI Human Research Training

Current human subjects training is required of anyone interacting/intervening with human subjects or obtaining identifiable data/specimens.  To satisfy this requirement, Harvard University offers human subjects training through CITI (Collaborative IRB Training Initiative). If you do not have an HUID, you will need to have a Harvard affiliate/sponsor request one for you per the Harvard University Person of Interest (POI) Policy. The Office of Regulatory Affairs and Research Compliance does not sponsor researchers or submit this on behalf of POIs.

The HLC IRB accepts the following course:

  • Biomedical Research Investigators
  • Social & Behavioral Research Investigators

The following courses do not satisfy the requirement to complete human research training: Conflicts of Interest, Export Compliance, Good Clinical Practice Course, Information Privacy and Security, Responsible Conduct of Research, IRB Members, or IRB Chairs.

Harvard University’s CITI training includes both basic and refresher training curriculum. Basic training consists of 7 required modules and 3 electives, and is valid for 3 years. Refresher training includes 5 elective modules and is also valid for 3 years.

The HLC IRB will accept any Organization’s CITI curriculum in the accepted modules in lieu of its own to satisfy either basic or refresher training. Refresher training credit may also be obtained by attending three or more Education Series Sessions during the academic calendar year.

IRB approval may not be granted for proposed Human Research where any staff member’s human research training remains incomplete.

New CITI Users

For individuals who do not have a CITI account (either through Harvard or another organization), visit CITI at and click on the “Register” button. Follow these instructions for registering as a new learner.

As part of the registration process, you will be asked to “Select Your Organization Affiliation.” Please select “Harvard University SSO.”  If you need to fulfill training requirements for more than one institution, you may affiliate with multiple institutions.  Once registered, you may indicate your preference for completing either the Biomedical or Social & Behavioral education modules.

Once you select “Continue to SSO Login/Instructions,” the page will direct you to the Harvard Key log in.

Existing CITI Users

If you have previously completed CITI training through another organization, you may continue to log in under this account and complete CITI to satisfy Harvard’s human subjects training requirements, as needed. You will not be required to complete Harvard’s CITI curriculum. You may choose to select “Harvard University” as an affiliate organization under “Select Your Organization Affiliation.”  Doing so will allow the HLC IRB to access your CITI training certificate.
