This study explores the state of undergraduate human resource management (HRM) curricula worldwide in an effort to understand the extent to which there is an agreed-upon body of knowledge underpinning the field of HRM. We reviewed the undergraduate curricula for all business schools that were accredited by either the Association to Advance Collegiate Schools of Business or European Quality Improvement System in 2014-2015. Of the 281 HR programs that we identified, programs require an average of 3.4 HR classes. The most common required courses were Human Resource Management (239 schools), Compensation (or Compensation & Benefits; 123 schools), and Staffing (or Recruitment & Selection; 113 schools). Although we did find similarities between programs, we also find that there are significant differences in the required courses of HRM programs worldwide. We additionally examine institutional pressures from major professional HRM associations, and find evidence that these organizations do influence HRM curricula toward greater similarity. In particular, schools in regions with a major professional HRM organization are more similar than schools in other regions. Additionally, schools in the United States that are aligned with Society for Human Resource Management curriculum guidelines are more similar than schools that are not Society for Human Resource Management aligned.
