American Chemical Society
From Academic Kids
The American Chemical Society (ACS) is a learned society (professional association) based in the United States that supports scientific inquiry in the field of chemistry. The ACS was founded in 1876. It currently has 163,000 members at all degree levels and in all fields of chemistry. The ACS holds bi-annual national meetings covering the whole of chemistry, plus dozens of smaller conferences in specific fields. Its publications division produces some two dozen first-rate scholarly journals (the oldest of them, Journal of the American Chemical Society, was established 125 years ago) and several book series. The ACS' primary source of income is the Chemical Abstracts Service.
The American Chemical Society also sponsors the United States National Chemistry Olympiad (USNCO), a contest used to select the four-member team that represents the United States at the International Chemistry Olympiad (IChO).
They also have a Division of Chemical Education (http://www3.uwm.edu/dept/chemexams/) that provides standardized tests for various subfields of chemistry. The two most commonly used tests are the undergraduate level tests for inorganic and organic chemistry. Each of these tests consists of 70 multiple-choice questions, and students are given exactly two hours to complete the exam.
