Mission

Since our founding in 1883, the mission of aavs has been to unequivocally oppose and work to end the use of animals in science and to oppose all forms of cruelty to animals. We achieve our mission by monitoring and investigating scientific uses of animals, exposing the inherent cruelty in animal experimentation. We then present reliable information and an informed viewpoint for advocating public policy changes. We provide resources to students, parents, educators, other nonprofit organizations, the media, policy makers, and members of the scientific community to advance the use of alternative, non-animal methods in schools and laboratories worldwide.
