The SAT Subject Tests is the collective name for 20 multiple choice stanardized tests given on individual subjects. A student typically chooses which tests to take depending upon college entrance requirements for the schools in which he or she is planning to apply. Until 1994, the SAT Subject Tests were known as Achievement Tests, and until January 2005, they were known as SAT IIs; they are still commonly known by these names. Every test is now a one-hour timed test. Historically, 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.
