Assess students' recall of eligibility criteria, exam structures, and recertification requirements for major HR credentials (SHRM‑CP/SHRM‑SCP, HRCI PHR/SPHR, and CIPD levels). Test knowledge of education and experience thresholds, exam domain outlines, question formats and timing, and ongoing maintenance pathways (e.g., professional development credits, re‑examination options, and CPD/reporting cycles), with emphasis on clear comparison across the three credential families.
