Scholastic Math Inventory is a computer-adaptive test.
In a computer-adaptive test, students are dynamically presented with questions. When a student answers a question correctly, the next question will be harder; if the student answers a question incorrectly, the next question will be easier. The item selection process continues until a strong level of certainty of the test taker’s ability has been established; the test ends and a scale score is provided.
Computer-adaptive tests tend to be shorter and more accurate than fixed-form tests because a student’s ability is discovered with fewer and more-targeted items. A computer-adaptive test saves time for the test taker who is not presented with questions that are far below or above his or her ability. A computer-adaptive test yields, with greater accuracy than a print test, a student’s true ability in the skill assessed.
