Update: TERA's History and Mission


Toxicology Excellence for Risk Assessment (TERA) has provided clients with independent, transparent science since 1995.


TERA solves human health risk challenges for diverse government and private sponsors through collaboration that emphasizes partnership building across scientific expertise and multiple perspectives to ensure the use of the best science. These strengths are the basis for TERA’s development of independent and science-driven analyses for risk assessment.


A world leader in independent scientific peer review, TERA provides in-person panel meetings, letter reviews, webcasts and webinars, in-house technical reviews, and workshops.




Example of Collaborative Work in Environmental Risk Assessment by TERA


The following text was prepared as part of EPA’s response to the US Senate hearing on the nomination of Michael Dourson to be Assistant Adminstrator of EPA’s Office of Chemical Safety and Pollution Prevention.  This text, not widely shared at the time, demonstrates the extensive mischaracterization of TERA’ long and successful history of independent, nonprofit science.  Any and all parts of this text can now be cited or quoted as needed.
