Working in collaboration with public, private and specialist academic sector organisations, WTACH determines best practice ethical principles and standards in line with the most robust global research available.

A community of like-minded organisations and individuals, WTACH seeks to ensure that the unique attributes, history and cultural values of the world’s communities are celebrated and preserved for generations to come."
