IRB Access

Before you have access to Cayuse, you must complete the following steps:

Go to and click the ‘R�𲵾����ٱ��’ button (upper right corner).   Under ‘Select Your Organization Affiliation,’ type in 'Texas Tech University Health Sciences Center.'   Continue setting up your account by following the Registration steps #1-7 below.

Steps 1-6:  Answer the questions regarding ‘Personal Information’.  NOTE: Register with your �㽶ֱ�� or TTU email address unless you do not have either (i.e., you are an Outside Collaborator).  NOTE:  If you are interested in CEU credit, answer the questions in Step 5 accordingly.

Step 7:  You must answer these questions correctly as they determine which course(s) you will receive access to.  Please answer as instructed below:

• Question #1 – Select ‘Biomedical Investigator Course: Research Investigators, Research Personnel, and IRB members’.
• Question #2 – Answer this question based on whether or not you have previously completed the Biomedical Investigator Course (whether at �㽶ֱ�� or another institution).
• Question #3 – Select ‘Not at this time.’
• All other questions can be skipped.
• COVID-19 Question—The very last question on the list must be answered (by CITI). It concerns information about COVID-19 and remote contact tracing. Please note that �㽶ֱ�� does not require it.
• When you are done adding courses, click ‘Complete Registration’.

The ‘Biomedical Investigator Course’ (and any others you have selected) will now show in your CITI account under the ‘My Courses’ tab.  Click on the ‘Start Now’ button for the course.  You must complete each module before moving on to the next one.

�㽶ֱ�� requires an overall score of at least 90% to complete the course successfully.  Once you have completed the course, you can access the ‘My Records’ tab in your CITI account to access the completion report/certificate.

Conflict of Interest/Commitment (in Research) Disclosure

�㽶ֱ�� policy requires that all research study personnel disclose any actual (or potential) conflict of interest and have a current financial disclosure on file.  This is done by completing the Conflict of Interest and Commitment (COIC) Training and Disclosure module at least annually AND updating within thirty (30) days of significant financial interest changes.  You will need to complete the COIC module if you are:

• Research PERSONNEL involved in the design, conduct, or reporting of human subject research - both Non-Exempt and Exempt studies
  (this applies to all �㽶ֱ�� Faculty/Staff/Residents/students)
• Research STAFF involved in designing, conducting, or reporting human subject research (i.e., RIO, CRI, etc.)
• Listed as study personnel on any grant administered through the �㽶ֱ�� OSP (including educational and public service grants)
