Exposure Decision



The Exposure Decision Analysis Registry program distinguishes OEHS professionals who have acquired the skills and knowledge to effectively manage workplace exposure and monitoring data. Given basic characterization and monitoring data, individuals with the Registered Specialist: Exposure Decision Analysis credential have the knowledge and skills to make informed decisions about worker exposure and exposure uncertainty.​


There are no specific requirements for candidates to be eligible to sit for the competency assessment.  However, training and/or experience in using IH data interpretation tools, and proficiency in the knowledge areas indicated in the Body of Knowledge, will assist in passing the competency assessment.​

The EDA Registry Program is provided at no cost as a service to the IH Community. If you are interested in taking the competency assessment, please contact AIHA Registry Programs staff​.
