at the beginning of world war ii, utah state was one of six colleges selected by the united states navy to give a primary school in the highly unusual electronics training program (etp). starting march 23, 1942, and each month thereafter, a new group of 100 navy students arrived for three months of 14-hour days in concentrated electrical engineering study. smart gymnasium was converted to a dormitory, and old main was fitted out for classrooms and laboratories. larry s. cole was named program director and waldo g. hobson was the director of instruction. etp admission required passing the eddy test, one of the most selective qualifying exams given during the war years. at a given time, some 300 navy students were on the campus, greatly augmenting the war-years regular enrollment of 1000. sidney r. stock had earlier developed the radio and aviation department, and entered the navy as a lieutenant commander to assist in organizing electronics training. he was a member of the committee in washington that planned the etp, and shortly returned to utah state as the officer-in-charge. the etp primary school continued at utah state until august 1944, graduating about 2,750 students in 30 classes.
