"The ACT (... American College Testing) college readiness assessment is a standardized test for high school achievement and college admissions in the United States produced by ACT, Inc. It was first administered in November 1959 by Everett Franklin Lindquist as a competitor to the College Board's Scholastic Aptitude Test, now the SAT Reasoning Test. The ACT originally consisted of four tests: English, Mathematics, Social Studies, and Natural Sciences. In 1989, the Social Studies test was changed into a Reading section (which included a Social Studies subsection) and the Natural Sciences test was renamed the Science Reasoning test, with more emphasis on problem solving skills. In February 2005, an optional Writing test was added to the ACT... In the Spring of 2015, the ACT will start to be offered as a computer-based test that will incorporate some optional Constructed Response Questions; the test content, composite score and multiple choice format will not be affected by these changes. ...
All four-year colleges and universities in the U.S. accept the ACT, but different institutions place different emphases on standardized tests such as the ACT, compared to other factors of evaluation such as class rank, GPA, and extracurricular activities. The main four tests are scored individually on a scale of 1–36, and a Composite score is provided which is the whole number average of the four scores." [ACT (test). Wikipedia]
