Announcement

  • New Ventilation Equation Sheet here.

Starting with the Spring 2025 Board for the Global EHS Credentialing/ABIH CIH Exam,
all ventilation equations will be based on the following manual:

“Industrial Ventilation: A Manual of Recommended Practice for Design, 31st Edition © ACGIH 2023.”
These equations and conversions, as well as an embedded scientific calculator, will be available during the examination. The pre-test tutorial will explain how to access both.

  • The new, single CPEA certification exam—available in the first quarter of 2025 — combines EHS best practices used by Certified Professional Environmental Auditors (CPEA) and Certified Professional Safety Auditor (CPSA) professionals.
  • More information on the new CPEA Exam is here.
  • Find the CPEA blueprint here.

The Board for Global EHS Credentialing is pleased to announce two new EHS Credentials:
Certified Associate in Environment, Safety, and Health™ (CAESH™) and Certified Professional in Environment, Safety, and Health™ (CPESH™).

As of January 2024, the former GES and QEP test forms were retired and replaced by the new GES and QEP Comprehensive Exams. All approved candidates must take the updated exams. New blueprints are available for the Qualified Environmental Professional (QEP) and General Environmental Science (GES) written exams. For More Information.
