Professional certificates in human resources are offered by colleges, universities, professional development centers, career training centers, and professional organizations. These certificate programs may count towards continuing education requirements or they may be credit-free courses that are for the purposes of professional development only. Some of these certificate programs might also earn the recipient college credit. eCornell, Cornell University's online education system, has several human resources certificates available. Some of the most popular programs include selection and staffing, compensation and benefits, performance management, and employee relations. Post University also offers an online human resources certificate. This program includes core courses in human resource management and electives in occupational safety and health, labor relations, training and development, and compensation and benefits.
