Exam outline and official sources

National Board of Public Health Examiners (NBPHE) · Current issuer-linked CPH Exam Content Outline, verified 2026-10-09, and Candidate Handbook dated October 2026. NBPHE's outline webpage states that the outline was updated on August 1, 2024 following its 2022 job task analysis. The currently linked PDF uses Health Outcomes and Population Perspectives for domain 10; it provides no separate effective date for that wording change. The assigned workbook label maps directly to the official CPH examination, and the canonical slug is preserved.

This original 20-question sample covers selected topics across the outline. It does not reproduce official exam questions or cover every tested topic.
