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.

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.
