The NC3Rs: Pioneering better science

If you are a scientist, animal technician, veterinarian, regulator, funder or policy maker, the NC3Rs can help you to:

Drive scientific and technological developments that replace, reduce or refine the use of animals in research (the 3Rs)
Ensure your animal experiments are as robust and reproducible as possible
Provide the best welfare for laboratory animals

Science-led and evidence-based, we fund research and early careers, foster collaborations between universities and industry to develop and commercialise 3Rs technologies, and provide information on the latest advances to put the 3Rs into practice.
