The aPHR is built on five functional areas, and HRCI publishes an exact weight for each. The exam is 90 questions (65 scored) and tests foundational HR knowledge across the employee lifecycle - no HR experience is required to sit it. Because the weights are published, you can study strategically: the two largest areas together make up nearly half the exam. Confirm the current outline on the HRCI certification page.
The five functional areas (with weights)
These percentages come from HRCI’s official aPHR Exam Content Outline:
- Compliance & Risk Management (25%) - complying with laws, regulations and policies and managing organisational risk. Covers US employment laws (for example EEOC, Title VII, ADA, FLSA, I-9, the WARN Act, NLRA), workplace health, safety, security and privacy (for example OSHA, HIPAA, Sarbanes-Oxley), risk assessment and mitigation, records retention, and the risks of restructuring such as mergers and downsizing.
- Employee Relations (24%) - monitoring and addressing morale, performance and retention. Covers mission, vision and value statements; how HR supports organisational goals through policies and HRIS; engagement, recognition, stay interviews and surveys; workforce and performance management; complaints, investigations, confidentiality and conflict resolution; and diversity and inclusion.
- Talent Acquisition (19%) - the full hiring process. Covers identifying staffing needs (forecasting, job analysis, job descriptions), sourcing (employer branding, job postings, referrals), screening and selection (interviews, assessments, bias), the hiring and onboarding lifecycle, and recruiting technology such as applicant tracking systems and metrics like time-to-fill.
- Compensation & Benefits (17%) - the elements of a total rewards package. Covers compensation strategy and pay structures, health and insurance programmes, supplemental wellness and fringe benefits, retirement plans (for example 401(k), 457(b)), and payroll processing including taxation, deductions and garnishments.
- Learning & Development (15%) - building employee skills. Covers the purpose of orientation, instructional design (for example knowledge, skills and abilities, the ADDIE model, needs analysis), training formats and delivery techniques, change management, and methods to track development and measure training effectiveness (for example a learning management system).
How to read the structure
Because the weights are published, let them guide your hours. Compliance & Risk Management (25%) and Employee Relations (24%) are nearly half the scored questions, so they deserve the most study. The remaining three areas - Talent Acquisition (19%), Compensation & Benefits (17%) and Learning & Development (15%) - are closer together and matter too, but you can scale your time to their weights.
How to study it
Learn each area at a foundational level: you need to recognise and understand HR concepts, not run them as an experienced practitioner would. Pay particular attention to US employment-law vocabulary in the Compliance area, which trips up newcomers. Remember the aPHR is the entry-level, knowledge-based credential; the PHR (which requires HR experience) is the next step. Confirm the current outline and eligibility on the HRCI certification page.
