In the 1940s, when Taylor was an international director of Rotary, he offered the Four Way Test to the organization, and it was adopted by Rotary for its internal and promotional use. Never changed, the twenty four word test remains today a central part of the permanent Rotary structure throughout the world, and is held as the standard by which all behaviour should be measured. The test has been promoted around the world and is used in myriad forms to encourage personal and business ethical practices. Taylor gave Rotary International the right to use the test in the 1940s and the copyright in 1954. He retained the rights to use the test for himself, his Club Aluminum Company and the Christian Workers Foundation.
