- 9 - The above table represents the total number of different students registered. It is interesting to note the result when registration is compiled on the basis used by the State colleges for determining equivalent full—time enrollment. The figure used by the state colleges is to count one full-time student for each 15 units of registration. On this basis, we find the California Polytechnic School enrollment would be 580.9 or 581 students. The study on this basis shows that the average unit load of students in the agricultural curricula is 17% and those in the industrial division 19 units. The table follows: Actual Average Equivalent Enrollment Units on 15-Unit Basis Agriculture 263 17 1/2 306.1 Industry 217 19 274.8 Total 480 580.9 Difference in the average number of units between the agricultural and the industrial curricula is found in two conditions. First, agriculture students spend considerable laboratory time in the conduct of their own projects. Only one unit of credit is given for this laboratory time, since the projects are in the main those of commercial type which return the student an actual profit; therefore, only credit is given for that time involved in the actual laboratory exercises of record-keeping, and project seminar. Industrial unit registration average is kept at a high level through requirements in the aeronautics division, where students must fulfill pupil- hour requirements of the United States Department of Commerce for license examinations, as well as cover a great amount of ground in technical courses and laboratory practice. On the basis of agricultural student project work, the agricultural students put in an equal number of hours, some longer hours, but receive less formal credit.
