As an additional study tool for the CBA and CBF designation exams, NACM offers practice exams. The practice exams use sample questions on relevant topics to simulate the level and types of questions found on the actual exam. Please note that the practice exams are intended to provide a sampling of the CBA and CBF examsâ€™ questions and scope. The questions on the practice exam are not necessarily the same questions that will appear on the actual exams. For more detail on the certification exams, please refer to the Exam Study Guides.
