The Certified Payroll Professional (CPP) designation is an exam-based payroll certification attained by individuals who have achieved a certain level of professional competency through both the acquisition of knowledge and direct payroll experience. According to Payroll.org's online copy of the CPP Examination Candidate Handbook "A payroll professional must be proficient in all aspects of taxation and tax reporting, MIS, human resources (including benefits), and accounting as each of these relate to the payroll environment.Upon successful completion of the CPP Examination, CPPs may be eligible to receive up to fifteen (15) undergraduate college credits as recommended by the American Council on Education’s Credit by Examination Program."
