The American college Testing- ACT is a standardized test for college admissions in the United States. It was administered in 1959 for the first time and has undergone several changes since then. In 2005, ACT has introduced optional writing test, mirroring changes to the SAT

The ACT has seen a gradual increase in the number of test takers in 2011 the ACT surpassed the SAT for the first time in total test takers; that year, 1,666,017 students took the ACT and 1,664,479 students took the SAT. All the colleges and universities in the U.S. accept ACT.

The four components of the test 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.

According to the various universities in the USA, colleges that also require students to take the SAT Subject Tests do so regardless of whether the candidate took the SAT or ACT; however, some colleges accept the ACT in place of the SAT subject tests and some accept the optional ACT Writing section in place of a SAT Subject Test.
