ADE's mission is to assess all students and to collect, analyze and distribute reliable test data and public K-12 school accountability information. The information program provides for the collection and reporting of statewide student achievement data through administration of both a nationally standardized, norm-referenced achievement test and a test of the Arizona Academic Standards, developed in conjunction with Arizona educators. Information on student achievement and other measures of school accountability are collected, analyzed and disseminated to educators, policy makers and the public.
