Introduction to the CPH Exam
The Certified in Public Health (CPH) exam is a credentialing examination that validates a public health professional’s knowledge and skills. It is offered by the National Board of Public Health Examiners (NBPHE). For epidemiologists, obtaining the CPH credential signifies a commitment to the field and demonstrates expertise in key public health competencies.Eligibility Criteria
To be eligible for the CPH exam, candidates must meet certain criteria. Generally, this includes having a degree from a Council on Education for Public Health (CEPH)-accredited institution or a minimum of five years of public health work experience. Prospective candidates should review the
eligibility requirements outlined by the NBPHE.
Exam Content and Structure
The CPH exam comprises 200 multiple-choice questions that cover a wide range of public health topics. These are divided into five core areas and seven cross-cutting areas. The core areas include:1. Biostatistics
2. Environmental Health Sciences
3. Epidemiology
4. Health Policy and Management
5. Social and Behavioral Sciences
The cross-cutting areas cover topics such as communication, diversity, and ethics. For an epidemiologist, a deep understanding of the epidemiology section is crucial.
Key Topics in Epidemiology
The epidemiology section of the CPH exam includes several critical topics:-
Study Designs: Understanding the different types of
epidemiological study designs, such as cohort, case-control, and randomized controlled trials, is essential.
-
Measures of Association: Knowledge of risk ratios, odds ratios, and incidence rates are fundamental to analyzing epidemiological data.
-
Disease Surveillance: Familiarity with disease
surveillance systems and outbreak investigation techniques is important.
-
Bias and Confounding: Recognizing and adjusting for bias and confounding factors in epidemiological studies is a key skill.
-
Statistical Methods: Proficiency in statistical methods used in epidemiology, including regression analysis and hypothesis testing, is necessary.
Preparation Tips
Preparing for the CPH exam requires a strategic approach. Here are some tips for success:1.
Study Materials: Utilize textbooks, online courses, and practice exams tailored to the CPH exam. The NBPHE offers a list of recommended resources.
2.
Practice Questions: Regularly practice with sample questions to become familiar with the exam format and timing.
3.
Review Core Competencies: Thoroughly review the
core competencies outlined by the NBPHE, focusing on areas where you feel less confident.
4.
