The videos were created and presented by leading experts, including lead developers of the free statistical analysis tools. An online practice exam is provided at the end of the webinar for people to test their learning and get feedback on areas where further review is needed.
  • Free Online Independent Validation of Competency and Performance via the AIHA Exposure Decision Analysis Registry Exam. The AIHA Exposure Decision Analysis (EDA) Registry program assesses competency in the skills and knowledge necessary to make informed decisions about worker exposure and exposure uncertainty. The program is offered at no cost as a service to the OEHS community. The goal of this program is to improve the accuracy and efficiency of exposure assessment decisions that can be made when using statistical analysis tools. The assessment is composed of two parts: 1) a multiple-choice section that focuses on relevant general knowledge areas; and 2) a multiple-choice section based on the interpretation of supplied datasets.
