The PHR covers five HRCI domains, dominated by Employee and Labor Relations at 39%. It is an operational, US-centric exam that tests how the HR function runs day to day, with a strong base in US employment law. Confirm the current outline on the HRCI certification page.
| Domain | Weight | What it covers |
|---|---|---|
| Employee and Labor Relations | 39% | Employee relations and engagement, performance and discipline, US labor relations and law |
| Business Management | 20% | HR’s role in the organisation, compliance and risk, ethics, HR metrics |
| Talent Planning and Acquisition | 16% | Workforce planning, sourcing, recruiting, onboarding |
| Total Rewards | 15% | Compensation structures, benefits programs, pay compliance |
| Learning and Development | 10% | Training delivery, employee development, performance support |
How to read the weights
Employee and Labor Relations alone is more than a third of the exam, so it deserves the most study time. Business Management is the next largest and frames HR within the wider business. The remaining three domains - Talent Planning and Acquisition, Total Rewards and Learning and Development - are smaller but still add up to 41% together, so do not skip them.
How to study it
Study US HR operations and employment law, and focus on applying rules to realistic workplace situations rather than memorising definitions. Note that the PHR differs from the SHRM-CP: it is technical and operational, not behavioural, and it requires HR experience to qualify.
