The SAT Subject Test in Chemistry was a one-hour multiple choice test given on chemistry by The College Board. A student chose whether to take the test depending upon college entrance requirements for the schools in which the student was planning to apply. Until 1994, the SAT Subject Tests were known as Achievement Tests; until January 2005, they were known as SAT 2s; they are still well known by the latter name. On January 19 2021, the College Board discontinued all SAT Subject tests, including the SAT Subject Test in Chemistry. This was effective immediately in the United States, and the tests were to be phased out by the following summer for international students. This was done as a response to changes in college admissions due to the impact of the COVID-19 pandemic on education.
