Horses were domesticating by humans thousands of years ago.

In 1929, E.F. Lindquist, a professor in the University of Iowa College of Education, began designing tests for the Iowa Academic Meet. The purpose of the meet was to identify exemplary high school students. Test-takers began with a first round of testing. This round occurred during the school day and covered ten core academic subjects. Students who scored well in the first round participated in district-level tests that were more difficult. High-scorers from the second round participated in a third round of testing. The top ten students in each subject area were rewarded with medals at a banquet. Although the test was a success, Lindquist wanted to reduce the competitive aspect of the test. To achieve this goal, Lindquist renamed the test the Iowa Every-Pupil Achievement Testing Program.

The tests popularity provided Lindquist with the opportunity to study how to best write, administer, and score a standardized test. However, Lindquist was not yet satisfied. He grew concerned that the test focused too much on rote memorization of content rather than on skill development. Lindquist began to work on a test for middle school students that would test skills. This test which was first administered in 1935 became known as the Iowa Test of Basic Skills. In 1942, the Every-Pupil test is discontinued and replaced with the Iowa Tests of Educational Development. As Lindquist had hoped, this test focused on testing skills rather than pure content memorization.

By the late 1950s, Lindquist had gained significant renown in the world of standardized testing, so he became involved in the process of developing a college admissions testing program. Although the SAT had been a commonly used admissions test since 1926, it was primarily marketed in the northeast and used as an admissions test for universities in that region. Schools outside this area used a variety of different tests that covered different content and was administered at different times. This led to unreliable results.

In 1958, that a standardized, national test be developed was proposed by Lindquist. He also hoped that, unlike the SAT, the new test would measure academic achievement so that it could be used to gauge each student’s level of preparation for college-level work.

Lindquist and a man named Ted McCarrel began developing the new test. One of McCarrel's main jobs was contacting admissions officers and convincing schools to use the new test. However, like the SAT, the ACT began as a regional test. Unlike the SAT, however, it was primarily used in the Midwest. With time and effort, the test became more popular in other parts of the country.

In 1959, the ACT was administered for the first time. The test was similar to the Iowa Tests of Educational Development. It consisted of four parts; English, math, social studies, and natural science. The social studies and natural science portions required students to interpret readings from each field; thus, Lindquist was able to maintain his goal of testing skills rather than memorized facts. Students had forty-five minutes to complete each section of the test. The ACT quickly became a staple of the college admissions process. In the first year, 132,963 students took the test, and that number grew in subsequent years.

Today, many colleges and universities in the U.S. accept ACT results from students applying for admission. So, don't worry! I'm sure your college will accept it too!

Adapted from The Origin of Species by Charles Darwin (ed. 1896)

Look at a plant in the midst of it’s range. Why does it not double or quadruple its numbers? We know that it can perfectly well withstand a little more heat or cold, dampness or dryness, for elsewhere it ranges into slightly hotter or colder, damper or drier districts. In this case, we can clearly see that if we wish in imagination to give the plant the power of increasing in number, we should have to give it some advantage over its competitors, or over the animals of the wild that prey on it. On the confines of its geographical range, a change of constitution with respect to climate would clearly be an advantage to our plant; but we have reason to believe that only a few plants or animals range so far, that they are destroyed exclusively by the rigor of the climate. Not until we reach the extreme confines of life, in the Arctic regions or on the borders of an utter desert, will competition cease. The land may be extremely cold or dry, yet their will be competition between some few species, or between the individuals of the same species, for the warmest or dampest spots.

Hence we can see that when a plant or animal is placed in a new country amongst new competitors, the conditions of its life will generally be changed in an essential manner, although the climate may be exactly the same as in its former home. If it’s average numbers are to increase in its new home, we should have to modify it in a different way to what we should have had to do in its native country; for we should have to give it some advantage over a different set of competitors or enemies.

It is good thus to try in imagination to give to any one species an advantage over another. Probably in no single instance should we know what to do. This ought to convince us of our ignorance on the mutual relations of all organic beings; a conviction as necessary, as it is difficult to acquire. All that we can do is to keep steadily in mind that each organic being is striving to increase in a geometrical ratio; that each at some period of its life, during some season of the year, during each generation or at intervals, has to struggle for life and to suffer great destruction. When we reflect on this struggle, we may console ourselves with the full belief that the war of nature is not incessant, that no fear is felt, that death is generally prompt, and that the vigorous, the healthy, and the happy survive and multiply.
