Idaho does not follow Daubert or Frye. Instead, Idaho applies its own Rules of Evidence 702 and 703 to determine the admissibility of an expert’s opinions. Nield v. Pocatello Health Servs. (2014), 156 Idaho 802, 850, 332 P.3d 714, 762. Under those rules, an expert must be “qualified.” I.R.E. 702. A qualified expert needs “practical experience or special knowledge,” but formal training is not required. Weeks v. E. Idaho Health Servs. (2007), 143 Idaho 834, 837, 153 P.3d 1180, 1183
