This guide is designed to give the student helpful information about Arizona's Instrument To Measure the Standards (AIMS) for high school. The guide provides examples of the type of questions students see on AIMS and explains how items are scored. It does not teach what the student needs to know to do well on AIMS, but it will help the student know what to expect. AIMS consists of multiple choice, short-answer, and extended writing questions. Some test-taking strategies are outlined, and descriptions are given of the reading, writing, and mathematics tests. Appendixes contain the scoring keys for the sample test items included for each area, the writing rubric, the AIMS mathematics reference sheet, and a review of test taking strategies. (SLD)
