When the Council convened for its 1946 annual meeting, it included 50 boards representing all states and U.S. territories that had laws governing the practice of engineering. By 1950, Alaska, Hawaii, the District of Columbia, and Puerto Rico had joined that group.
In 1948, Secretary Legaré remarked that “the functions of the Council now seem to have the wholehearted support of most of the member boards, engineering societies, engineering colleges, and others concerned.”
The Council’s Subcommittee on Written Examinations reported that a syllabus of exams was essential for equivalent exams to be established among boards. In 1953, it proposed such a syllabus, and delegates accepted it at the annual
meeting. It ensured distribution of questions covering the entire subject matter during 
a two-day exam
period: fundamentals on the first day and professional applications on the second.
In 1955, the Northeast Zone pioneered the way for uniform exams when 277 engineering seniors were examined in eight states in the zone at one time using the same exam.
In 1958, the Council saw the first woman appear as a discussant at its annual meeting. Mrs. Clemmie Wall of the Missouri Board participated in the presentation of the State Board Secretaries Conference.
By 1959, the Council was generally recognized as the national agency of all engineering registration boards and as a bureau of information regarding registration.
