To be a leading force in the development and use of reduction, refinement, and replacement alternatives in research, testing, and education to protect and enhance the health of the public.


  • Promote and support research in the development of in vitro and other alternative techniques.
  • Serve as a forum to foster discussion among diverse groups leading to creative approaches to facilitate acceptance and implementation of alternatives.
  • Provide reliable information on the science, philosophy, and public policy of alternatives to academia, government, industry and the general public.
  • Educate and train in the application of alternatives.

* Alternatives are defined as new methods that refine existing tests by minimizing animal distress, reduce animal usage, or replace whole animal tests.
