One reform that I believe would represent a significant improvement over the current grading system would be to replace the grading curve with a standards-based system, where an "A" corresponds to "x level of achievement" rather than "x percentile of the class." This is quite a large change, however, and would probably require implementing some smaller reforms first (like as I mentioned above, an upfront assessment policy with outcomes and details of assessments and a post-exam analysis of student performance and the exam itself) to familiarize staff with the new tools necessary to make the switch. So building on the division-of-labor/distinguishing roles within reform advocates idea, perhaps one individual or group can argue for this, taking the long-view, while others can present the more achievable short-term incremental reforms.
