An achievement test is a measure of developed skill or knowledge. The most common type of achievement test is a
standardized test developed to measure skills and knowledge learned in a given grade level, usually through planned instruction, such as training or classroom instruction. Achievement tests are often contrasted with ability tests, which measure more general and stable
cognitive traits. Achievement test scores are often used to determine what level of instruction a student is ready for. High achievement scores usually indicate a mastery of grade-level material, and the readiness for advanced instruction. Low achievement scores can indicate the need for remediation or repeating a course grade.
