Professional in Human Resource (PHR) certification is the next step for human resource specialists interested in obtaining a higher-level human resource (HR) position. Successful candidates have between two and four years of professional HR work experience, and approach problems using logic and organization, but have not yet had the opportunity to delve deeply into a range of professional experiences or work on projects of increasing complexity. 
PHR certification can be earned by taking the PHR exam. The exam concentrates on six areas.

Candidates with a bachelor's degree must demonstrate two years. Candidates with less than a bachelor's degree must have four years of professional experience in order to qualify to take the PHR Certification exam.
