Ariz. Rev. Stat. § 15-755
In order to ensure that the educational progress of all Arizona students in academic subjects and in learning English is properly monitored, a standardized, nationally-normed written test of academic subject matter given in English shall be administered at least once each year to all Arizona public schoolchildren in grades two through twelve. All students with disabilities shall be included in all general state and district assessments, with appropriate accommodations and alternate assessments where necessary and as indicated in their respective individual education program, in accordance with 20 United States Code section 1412. The particular test to be used shall be selected by the office of the state superintendent of public instruction, and it is intended that the test shall generally remain the same from year to year. The national percentile scores of students shall be confidentially provided to individual parents, and the aggregated percentile scores and distributional data for individual schools and school districts shall be made publicly available on an internet web site, and the scores for students classified as "limited-English" shall be separately subaggregated and made publicly available there as well. Although administration of this test is required solely for monitoring educational progress, Arizona public officials and administrators may utilize these test scores for other purposes as well if they so choose.
