Other reports from schools, colleges, and universities indicate the widespread adoption of intelligence tests in determining the probable measure of success which a student will attain in his studies, or whether he is fitted, mentally, for the career he contemplates. The group tests of intelligence have demonstrated their value in educational work to such an extent that, following the lead of Columbia University, a large number of prominent American universities and colleges are employing tests of intellectual ability as at least partial substitutes for the time-honoured college entrance examinations. Instead of requiring each prospective student to take an examination in which he would be required to demonstrate that he remembered the facts learned in high school, the present scheme is to examine the men who desire to enter college by means of the psychological tests designed to measure general fitness and intelligence. The theory behind this movement is that men should be allowed to enter college provided their intelligence and mental capacity is such as would enable them to profit by the instruction, regardless of whether such men could recall the required percentage of the facts taught them by their high school teachers. This same philosophy will undoubtedly spread very widely through the high schools and elementary schools as well as through the colleges. A child should be allowed to undertake that work for which he is fitted by nature and intellectual capacity, regardless of what his past academic training may have been. It is unreasonable to require young men who, because of some accident, left school early in life and have continued their education through their own efforts, to go back and begin with younger pupils a course of study, which will have very little practical value to them, before they are allowed to undertake the professional courses they desire and are capable of undertaking at once. The group-examination method, which is employed by the majority of the Mentimeter tests, has been the greatest possible stimulus to the employment of intelligence examinations, because of the great saving of time which it affects over the method of individual examinations. CHAPTER VIII MENTAL TESTS IN INDUSTRY The case for scientific mental tests as a prerequisite to the employment of beginners in business and industry has been well put by Dr. Henry C. Link. In addressing a convention of California railroad men, Doctor Link said:
