In the United States, engineers and surveyors are licensed at the state and territory level. U.S. licensure began in 1891 when California passed legislation to regulate surveyors. Engineering followed in 1907 when Wyoming began requiring licensure for both engineers and surveyors. As more states enacted similar legislation over the next decade, U.S. licensing boards began to see a need for a national council to help improve uniformity of laws and to promote mobility of licensure.
