It is the standard practice in colleges and universities to administer to all entering students a battery of tests which are designed to measure the aptitude and ability of students. Each institution uses in its test battery those tests which are best suited to its particular needs, but in the main they consist of measures of general mental ability, the ability to understand and use the English language and the ability to understand and to use mathematical symbols. These tests are available to the institution through companies which construct and standardize tests of all kinds. In addition to these tests, others may be constructed by the departments of an institution and validated for use in that department or school. The test battery or the Utah State Agricultural College consists or a combination of these two types. The English examination is the Educational Testing Service Cooperative English test Battery, the Mathematics test is a department constructed test, originally designed and constructed by Dr. Arden N. Frandsen.
