If you are engaged in human subject research, all study personnel who interact with subjects, participate in an intervention with subjects, or who access information about subjects which could reasonably identify the subjects must complete required training. At Purdue, required training is administered through CITI.

The Collaborative Institutional Training Initiative (CITI) Human Research Protections Training Course is a self-paced web-based training program covering core ethical concepts and regulatory requirements. Purdue University requires all individuals engaged in the conduct of human subject research to have current CITI certification, which may be updated by a refresher course after 5 years.

Training for New Users

The CITI Human Subjects Research Basic Course is required for all investigators and study personnel (i.e., Users) who have not previously completed a CITI human subjects research course.

At a minimum, Users must select and complete the curriculum (called Learner Groups) that corresponds with their role in the research. However, we strongly recommend all Users, regardless of their role or type of research conducted, choose to complete on of the following Learner Groups to fulfill their CITI certification requirement.

  • Biomedical Research for Investigators and Key Personnel Learner Group
  • Social Behavioral Research for Investigators and Key Personnel Learner Group

Please see our guidance Research Roles and CITI Learner Groups to learn about each of Purdue’s offered Learner Groups.

Each Learner Group contains up to 16 required modules. Each module may take from 10 – 20 minutes to complete (typically 2-4 hours total), and most modules contain a quiz. The modules do not have to be completed all in one session. A minimum cumulative score of 80% is required to pass the Course.

Before entering the CITI website to begin training:

Investigators need to use either Internet Explorer 8 or later, or use a current version of Chrome, Firefox or Safari to access the CITI Course.

Know which Learner Group curriculum you need to complete. NOTE: Responsible Conduct of Research (RCR) training DOES NOT fulfill Purdue’s human subjects research training requirements.

Remember to record your username and password for future reference. If you forget your username or password, contact CITI. Purdue does not have access to that information.

You do not need to complete the entire Course in one session. Re-enter as often as you like, using your username and password, to complete the training.

You must complete all required modules with a cumulative score of 80% or better to pass the course.

Transferring CITI Certification From Another Institution

If you are a Purdue researcher who completed your CITI training at another institution, you can transfer your certification to Purdue. If you are a researcher who is affiliated with another institution but are collaborating on a Purdue study, we still require human subjects research training certification, but will accept equivalent certification from your home institution.

New Purdue Researcher Who Completed CITI Training at Another Institution

Any researcher who is new to Purdue and who completed his/her CITI training at another institution within the past two (2) years can transfer completion credit for modules shared between the researcher’s prior institution and Purdue.

  1. Log into your CITI account. If you can’t remember your user name and password, contact CITI.
  2. You need to be affiliated with both institutions (your prior institution and Purdue). Your Main Menu page will have a section called “My Learner Tools” similar to the screenshot below, but for your prior institution. Follow the “Click here to affiliate with another institution” link to add an affiliation.
  3. Select “Purdue University” and click “Next”.
  4. Once you have affiliated with both institutions, on the Main Menu page under Purdue University select “Add a Course or Update Learner Groups”. Enroll in the Purdue course that you want to transfer your completion credits to from your previous institution. You will need to enroll in the same stage of the course (Basic/Refresher) for a proper transfer to occur.
  5. Once you are enrolled in the Purdue course, any modules that are shared between the two institutions’ courses will have their credit transferred automatically. The researcher is responsible for completing any Purdue modules that were not completed by the transfer of credits.
  6. You will know you have successfully completed the Purdue course when on the Main Menu screen under “Purdue University Courses” the course status says “Passed” and the date of course completion. You can also print your completion report.

Non-Purdue Researchers Engaged in the Conduct of a Purdue Study

Researchers with completed training

    As mentioned above we will accept completion of equivalent human subjects research training from a researcher’s home institution. That training must be both:

      substantially equivalent to Purdue’s required training, and

      current according to the home institution’s education policy or was completed within the past five (5) years, whichever is most recent.

    The researcher will need to print his/her CITI certification and provide it to the Purdue PI for submission with the study application to the IRB.

Researchers without training

    A researcher who does not have current equivalent training from another institution, can either obtain certification from his/her own institution so long as it is equivalent to Purdue’s required training, or the researcher can complete Purdue’s CITI training by following the instructions above, Training for New Users.
