Benefits, in their own words...

[The EDA Registry Program] allowed for a total reassessment of our respiratory protection program to align with exposure data and analysis.

~ John Nelson, MS, CSP

Benefits, in their own words...

EDA fills the critical locus of determining when monitoring data resulting in discrete measurements of exposure are sufficiently characterized. There is very little discussion of the formal methodology to determine completeness of characterization otherwise. This is very important to understand when making decisions about the perpetuity of monitoring.

~ Spencer Pizzani, CIH

I use the statistical knowledge that I gained in preparing for the EDA Registry Exam on a weekly basis and have recommended the Making Accurate Exposure Risk Decisions online course and the EDA Registry to all of my coworkers and OEHS staff of contractors performing work at our campus.

~ Andrew Bryson, CIH, CSP, MPH

Benefits, in their own words...

Many of our clients are now requesting statistical analysis of historical exposure data, and ongoing exposure data that is routinely collected. This course has helped me define and use statistical models to outline data confidence to identify a negative exposure assessment.

The EDA Registry Exam {Registered Specialist: EDA credential} helps me stand out within the field of industrial hygiene as a professional able to use tools to improve the accuracy of my risk and exposure judgments.

~ Rustin Reed, PhD, CIH, CSP

Benefits, in their own words...

This registry process provides the tools necessary to deliver an extremely robust data analysis and conclusions for exposure data. It dramatically lowers the possibility of making false negative judgments and conveys the conclusions in an understandable and transparent fashion.

~ J. Barry Graffeo, CIH, FAIHA

Benefits, in their own words...

In my office, we have a lot of new graduates and early career professionals who have not had much experience in applying statistical analysis to the career field. The EDA Registry Exam is now one of our recommended onboarding tasks to help get newcomers up to speed. Items taught within the exam have also completely shaped how our organization analyzes data.

~ Alex Cardone, CIH, MPH
