College Board launched the SAT in 1900. Since then, the standardized test has gone through numerous changes from the scoring system to subject sections and everything else in between.
In 2005, SAT underwent significant changes in question formats, the addition of a compulsory written essay, and the shift from 1600 score scale to 2400.
In March 2016, another update to the SATs was made. This time, the maximum total composite score was brought back to 1600. The SAT total score system remains this way as of November 2020.
