The IO500 Committee, as of May 2019, consists of the three founding members (in alphabetical order), John Bent,Julian Kunkel, and Jay Lofstead, as well as a fourth member, George Markomanolis, who was a very active early community participant and joined the committee subsequently.

The committee governs itself with the following rules:

1. All changes to the benchmarking scripts or methodology require all committee members to review and approve.
2. All changes to the website require all committee members to review and approve.
   1. Exception: additions to the News page require only 2 members to approve but must email edits out to the full committee.
   2. Exception: removing accidentally revealed internal information requires only 2 members to approve but must email edits out to the full committee.
   3. Exception: updating the webpage with new lists requires only the members attending the particular BoF.
3. By default, all submissions marked VALID by the io500.sh script are accepted. However, any committee member can raise an objection if they think a submission violates any of the IO500 rules. In typical situations, the committee will discuss the concerns with the submitter. After this discussion, the committee will vote. If 50% or more think the submission should be rejected, it will be rejected.
4. All requests for media interviews are discussed by the full committee who most unanimously decide how to respond.
