Professional HR certifications are impactful on an HR practitioner’s career. The Professional in Human Resources® (PHR®) and Senior Professional in Human Resources® (SPHR®) are some of the most widely held certifications among HR professionals in North America. Eligibility for the PHR and SPHR are both based on a professional level and educational requirements. In essence the PHR is operational and the SPHR is strategic. Each certification supports your career in a different—but equally vital—way. The book fee is non-refundable.
