There were several groups that had an impact in the expansion of the TWI programs around the world - US State Department, US Army, British Ministry of Labour, International Labor Organization (ILO) and Standard Oil.[5] In 1944, the British Ministry of Labour sent Frank Perkins to the US to evaluate the TWI programs.[6] In the summer of 1944, Perkins returned to England to establish a similar program. The British Ministry of Labour actively promoted the TWI programs, listing 65 countries in addition to the US and England where TWI was known to be in use as of 1959.[7] Expansion into Europe was led by Standard Oil, which led the translation efforts of the manuals into native languages. Some European TWI activity was done under the Marshall Plan by "Visiting Experts" (VE), with limited success.
