The REHS/RS Online Study Course is a self-paced learning experience designed to support entry- to mid-level environmental health professionals as they move from foundational knowledge toward practical application and credential readiness.
Grounded in the validated REHS/RS job task analysis and aligned with the REHS/RS body of knowledge, this course helps learners organize, connect, and apply core environmental health concepts in ways that reflect real-world practice. It is ideal for professionals who have gained foundational knowledge through education or field experience and are ready to deepen their understanding as responsibilities expand.
Course topics include:
- Food safety
- Onsite wastewater
- Drinking water
- Recreational water
- Housing and institutions
- Inspections
- Investigations
- Compliance review
- Risk assessment
Content is delivered in a modular format, allowing learners to progress sequentially or revisit specific topics as needed. The self-paced structure supports flexible learning without travel, fixed schedules, or time away from essential duties.
This course is one component of NEHA’s intentionally designed REHS/RS learning portfolio.
The REHS/RS Study Guide establishes foundational scientific and regulatory knowledge.
The REHS/RS Online Study Course builds on that foundation by reframing knowledge for applied professional use.
Finally, the REHS/RS Practice Exam allows learners to assess readiness and build confidence prior to sitting for the REHS/RS credential examination.
Agencies may use this course as part of onboarding, mentoring, or professional development pathways. Individuals may use it to consolidate experience, refresh knowledge, or prepare for credentialing as a professional milestone.
This course does not replace instructor-led training or the credential exam. Instead, it provides a structured, accessible bridge between learning, practice, and professional advancement.
