IRB 101

What is an IRB?

IRB is an acronym for Institutional Review Board. The IRB is responsible for the review and approval of all research involving human subjects, as well as scientific validity and ethical review.

What is Research?

In general, research is defined by the Department of Health and Human Services as a "systematic investigation, including research development, testing and evaluation, designed to develop or contribute to generalizable knowledge" (45 CFR 46.102(d)).

What is a human subject?

Per Federal regulations (45CFR46.102(f)), a human subject is defined as:  A living individual about whom an investigator (whether professional or student) conducting research obtains: 1.) Data through intervention or interaction with the individual, or 2.) Identifiable private information.

IRB Policies and Procedures, Manuals, and Other Regulations/Guidance

Information regarding the IRB's policies and procedures, manuals, regulations, and guidance can be found at and throughout the website.

Where can I find information related to a specific committee?

Each IRB committee has a page with its general description, information, and resources related to the committee which can be found at  The current board member roster for each committee can be found through these pages or at  A detailed listing of meeting deadlines and dates for each committee can be found through the committee page or at

How do I submit a study?

Studies are submitted through our electronic IRB submission system, eRIC. The link to eRIC as well as information about eRIC, quick guides, FAQs, and log-in troubleshooting information can be found at or by clicking on "ERIC (ELECTRONIC IRB SUBMISSION SYSTEM)" which is the third item down under the IRB in the menu on the left.

Is any training required?

Below is a brief overview of the different training requirements.  For more detailed information and instructions, please see our Training webpage at

What are the different review options?

Research applications are reviewed at one of three levels, depending on the level of risk to the human participants and on the federal regulations that define the categories of review. The levels of review are exempt, expedited, and full board review. The determination of what level of review is required is determined by the IRB staff, NOT the researcher.  Categories of research that can be reviewed via exempt or expedited review can be found at the following links:

To help evaluate the needs for IRB review, please refer to the OHRP decision charts:

What are the timelines for review?

IRB approval timeline for minimal risk studies/study submissions:

  • Review time for IRB members: 5 business days
  • Processing time for IRB Staff: 5 business days

Review timeline for greater than minimal risk studies/study submissions (full board review):

  • The study must be submitted before or on the deadline; the study will be reviewed at the meeting associated with the deadline.
  • Processing time for IRB staff, after the IRB meeting: 5 business days.

What are the meeting deadlines and dates for submissions to full board?

The IRB meeting deadlines and dates can be found at  Users can access both the google calendar for the IRB and/or the detailed listing of deadlines and meeting dates for each committee.  Users are able to subscribe to the IRB google calendar.  A feed of upcoming events including meeting deadlines and dates can also be viewed on the Main IRB webpage.

Do classroom projects require IRB review?

Before referring to the material below, please make sure you understand the basic definition of research on human subjects (described above).

International Research

International human research refers to research conducted outside the United States using participants from the local community. Such research involving Georgetown University researchers requires review and approval from the GU IRB. Human subjects outside of the United States who participate in research projects conducted or funded by HHS receive the same level of protections as research participants inside the United States.

The approval requirements can be time-consuming, such as translating consent forms, obtaining approval from the international research site, obtaining review and approval by a local ethics review board equivalent to an IRB, etc. Given the additional documentation and review requirements for international research, investigators are strongly encouraged to plan ahead to allow greater time for submitting the protocol application and obtaining IRB approval.

International research applications should identify whether there is a local IRB, Ethics Committee (EC), or government entity that will perform review in the host country. If local review has been conducted, a copy of the approval letter/notice should be included in the application. Please consult the International Compilation of Human Research Standards.
