What the Course Entails and Exam Details

Preparing for this exam requires a mastery of a diverse array of content domains that represent the daily responsibilities of an environmental health professional.

The course of study focuses heavily on the scientific principles underlying environmental public health and the practical application of regulations.

Core topics covered in the learning objectives generally include:

• Food Protection: Mastery of the FDA Food Code, inspection techniques, risk management, and foodborne illness investigation.
• Wastewater and Potable Water: Understanding treatment processes, sampling protocols, regulations for private and public water systems, and protecting water resources.
• Solid, Hazardous, and Infectious Waste Management: Protocols for proper collection, storage, disposal, and emergency response to spills.
• Vector Control and Pest Management: Identification of public health pests and effective, integrated control strategies.
• Institutional Health and Safety: Inspecting facilities like schools, daycare centers, and hospitals to ensure healthy environments.
• Statutes, Regulations, and Legal Processes: Understanding the legal framework, enforcement procedures, and administrative duties of a sanitarian.
• Epidemiology and Risk Communication: Principles of disease outbreak investigation and communicating public health risks effectively.

What to Expect in the Final Exam

The NEHA General Environmental Health (REHS/RS) final exam is a rigorous, comprehensive assessment that tests both theoretical knowledge and situational judgment.

Candidates should expect the following exam format and structure:

• Question Format: The entire exam consists of multiple-choice questions. These questions are designed to test not only recall but also the ability to apply science-based principles to real-world inspection scenarios.
• Total Questions: There are typically 225 questions included in the exam.
• Scoring Structure: Of the 225 questions, 200 are scored items, and 25 are unscored "pilot" questions used for future test development. You will not know which questions are unscored.
• Time Limit: Candidates are usually allotted four (4) hours to complete the examination, which is often split into two equal sessions of two hours each with a short break.
• Passing Score: NEHA uses a scaled scoring system ranging from 0 to 900. A scaled score of 650 is the required passing standard.
• Rules: The exam is closed-book. No external resources, references, or programmable calculators are permitted.

 How to Study and Exam Centers

Successfully passing this exam requires dedicated, multi-month preparation rather than last-minute cramming.

Here are actionable strategies to build your study plan:

Effective Study Strategies:

Utilize the Official NEHA Study Guide: This is the primary resource. Go through it systematically, highlighting key definitions, regulations, and processes.

Practice with Mock Exams: The use of dedicated NEHA General Environmental Health Practice Tests is essential. They help you get used to the phrasing of the multiple-choice questions and identify your weak areas for targeted review.

Master the FDA Food Code: Food safety often constitutes a large percentage of the exam; having a thorough knowledge of the current FDA Food Code is a must.

Review Mathematics for EH: Practice common calculations used in the field, such as metric conversions, area and volume calculations, pesticide application rates, and basic epidemiological statistics (incidence and prevalence).

Form a Study Group: Collaborating with peers preparing for the same exam allows for discussing difficult concepts and sharing resources.

Exam Centers and Scheduling:

The NEHA REHS/RS exam is administered in two primary ways:

• Pearson VUE Testing Centers: This is the most common method. Once NEHA approves your application, you will receive an "Authorization to Test" email. You can then schedule your computer-based exam at a local Pearson VUE facility at a time of your choice.
• NEHA Annual Educational Conference (AEC): NEHA often hosts a special in-person paper-and-pencil exam session at their annual conference for attendees who have pre-applied and been approved.
