ENGINEERING educators have recently been discussing the advisability of extending the undergraduate curricula to five or six years, and a plan has also been proposed requiring a preliminary period of study in the liberal arts college before admission to the engineering college. Extension of the undergraduate curricula has been suggested as a means of more fully covering the subject matter in the major field of study. Interest in this proposed plan of requiring a preliminary period of study in the liberal arts college has been heightened through a bill recently introduced in the legislature of the State of New York. This plan intends to give a more professional status to engineering, and credit for these additional years of study would be allowed to those engineers applying for professional licensure. As a result of the interest in engineering curricula and due to the impetus given by these proposed plans a general reexamination of curricula has been conducted by a large number of schools with the stated purpose of determining if the present curricula are meeting the aims and scopes of engineering education.
