To comply with a mandatory continuing professional development (CPD) program, practicing professionals must annually report CPD-related activities and their admissible hours according to well-defined regulator guidelines (Option B). This requirement is common across many regulatory bodies as it ensures that professionals are maintaining their skills and knowledge in line with current industry standards. The goal of CPD programs is to keep professionals up-to-date, competent, and capable in their respective fields, thus ensuring public safety and trust in the professions.
