Stanford Achievement Test

The Stanford Achievement Test is a standardized test used to measure academic knowledge of elementary and secondary school students in the United States. The test is available in 13 levels that roughly correspond to the year in school. Each level of the test is broken into sub tests or strands covering various subjects such as Reading Comprehension, Mathematical Problem Solving, and Science. Formerly known as the SAT, it was often confused with the Scholastic Aptitude Test. It is now more commonly referred to as either the Stanford or the SAT followed by the edition number, for example Stanford 10 or SAT 10, referring to the 10th Edition. The Stanford Achievement Test was formerly published by the Psychological Corporation (PsychCorp) and is now published by Harcourt Assessment, Inc.
