A CPA (Certified Public Accountant) is a professional accountant who has met state-level certification and work experience requirements and has passed the CPA examination. It is not equivalent to a graduate-level degree or master’s degree in accounting. In order to sit for the CPA exam, professionals need at least 150 credit hours. Since a typical bachelor’s degree is 120 credit hours, many CPA candidates enroll in a master’s degree in order to fulfill the full credit hours needed to sit for the exam.
