Data‐model validation of ground magnetic perturbation forecasts, specifically of the time rate of change of surface magnetic field, d B /d t , is a critical task for model development and for mitigation of geomagnetically induced current effects. While a current, community‐accepted standard for d B /d t validation exists (Pulkkinen et al., 2013), it has several limitations that prevent more complete understanding of model capability. This work presents recommendations from the International Forum for Space Weather Capabilities Assessment Ground Magnetic Perturbation Working Team for creating a next‐generation validation suite. Four recommendations are made to address the existing suite: greatly expand the number of ground observatories used, expand the number of events included in the suite from six to eight, generate metrics as a function of magnetic local time, and generate metrics as a function of activity type. For each of these, implementation details are explored. Limitations and future considerations are also discussed.
