Arizona’s Instrument to Measure Standards (AIMS) tested the old standards.
Spring 2014 was the last time AIMS was administered for reading, writing, and mathematics. AzMERIT, based on the new standards, will tell teachers, students, and parents if students are on track to be college and career ready upon graduation from high school. The Arizona Science Standards did not change, so students in Grades 4, 8, and high school will still take the AIMS Science test. High school students graduating after December 31, 2016 will no longer be required to pass the AIMS test to graduate high school.
