Manageability challenges, however, rarely prevent certification. There is a deep circuit split on this issue, with the Third, First, and Fourth Circuits applying a heightened standard for ascertainability that requires a class representative to propose an administratively feasible method of ascertaining class members at the class certification stage. The Eleventh Circuit, however, solidified the split by joining the Second, Sixth, Seventh, and Ninth Circuits in rejecting administrative feasibility as a class certification requirement.
