Would you like to become a Certified Indoor Environmentalist (CIE)? This designation demonstrates that you understand how to create healthy homes and buildings by preventing, diagnosing, and resolving indoor environmental problems. This online course prepares you to pass the CIE examination through a series of video lectures on exam topics such as contaminants, health effects, building science, HVAC, equipment, assessments, mold remediation, and industry standards and guidelines. The course also covers practice questions in detail and provides a practice examination to ensure you succeed at becoming a Certified Indoor Environmentalist.

Your clients want to be confident that they are hiring a trustworthy and competent consultant. One of the best ways to demonstrate your competency is to obtain a third-party accredited certification, such as the Certified Indoor Environmentalist (CIE). The CIE certification is sponsored by the American Council for Accredited Certification (ACAC). The CIE Prep Course will prepare you to pass the CIE examination. The examination is offered at computerized testing centers throughout the US and beyond. Certain experience requirements and fees apply to students obtaining certification; however, no experience is required to participate in the CIE Prep course.
