OBJECTIVE:
Over the past decade, interest has grown in understanding the public health workforce through both the competencies used to prepare professionals and the tasks they perform in practice. This study examines whether competencies and tasks are organized into similar fundamental domains, and the degree of similarity across datasets.

METHODS:
Four datasets developed by three US-based public health organizations were analyzed: the Council on Education for Public Health’s (CEPH) 22 foundational competencies, the Council on Linkages Between Academia and Public Health Practice’s (CoL) 56 sub-competencies, and two task datasets developed by the National Board of Public Health Examiners (NBPHE) representing the entire workforce (95 tasks) and governmental public health practice (54 tasks). The analysis began with a high-level comparison of organizational domains, followed by detailed cross-walks,

RESULTS:
At the domain level, the majority of structures were highly consistent across all datasets, with only minor differences. Using the CPH task framework as the reference, 69% of its tasks aligned with governmental public health tasks; using the governmental framework as reference, 52% aligned with CPH tasks, reflecting the broader scope of the CPH set. Competency alignment was similarly strong: 73% of CoL sub-competencies matched CEPH competencies, and 91% of CEPH competencies aligned when CEPH was used as the reference set. Cross-walks between task and competency datasets revealed that 97% of CPH tasks aligned with CoL competencies (81% with CEPH), and 93% of governmental tasks aligned with CoL (83% with CEPH).

CONCLUSIONS:
The high degree of alignment across leading competency and task frameworks indicates broad consensus on the essential domains of public health practice. This consistency provides confidence that public health professionals, regardless of training pathway, are guided by coherent expectations and can reliably demonstrate expertise and commitment to high standards.
