The TAAS, or Texas Assessment of Academic Skills, was a primary education standardized test used in Texas between 1991 and 1999, when it was replaced by the TAKS test. Prior to 1990, the test was known as the Texas Educational Assessment of Minimum Skills, or TEAMS. It was used from grades 3 to 10, at which point if the student passed he or she no longer needed to take the exam. A pass at the 10th grade level was required for graduation, but many opportunities for retesting (on different test versions) were available. In 1994, the final exam was raised to the 11th grade level.
