The SAT Subject Tests are 20 one-hour multiple-choice tests given in individual subjects. A student chooses which ones he or she will take, depending upon individual factors, such as college entrance requirements. Until 1994, the SAT Subject Tests were known as Achievement Tests; until January 2005 they were known as as SAT IIs, the name by which they are still well known. The exception to the one-hour time was the Writing test, which was divided into a 20-minute essay question and a 40-minute multiple choice section; it was discontinued after January 2005. A student may take up to three SAT Subject tests on any given date, which are the same dates as for the administration of the SAT Reasoning Test.
