The ARC 3.5m Users' Committee plays an important role in representing the interests of the broad user community. Each institutional member of ARC (including leasing partners) has a Users' Committee (UC) representative who participates in monthly teleconferences. The UC representatives serve as a conduit of information - both from the users to the management team as well as from the management to the users. The current (2025) UC representatives are as follows:
| Institution | Users' Committee Representative | ||
| University of Washington | Eric Bellm | ||
| University of Colorado | Adam Kowalski (Zach Berta-Thompson for Jan-Apr 2025) | ||
| New Mexico State University | Moire Prescott | ||
| Johns Hopkins University | Kevin Schlaufman | ||
| University of Wyoming | Chip Kobulnicky | ||
| Georgia State University | Misty Bentz | ||
| University of Virginia | Anne Verbiscer | ||
| University of Oklahoma | Michael Hayden | ||
| Brigham Young University | Aleksandr Mosenkov | ||
| Seattle University | Joanne Hughes Clark | ||
| Northeastern Astronomy Participation Group | Jeff Bary |
