The Performance Evaluation for Alaska's Schools (PEAKS) assessment is administered annually statewide to students in grades 3 through 9 in ELA and mathematics. It provides students the opportunity to show their understanding of "Alaska's English Language Arts (ELA) and Mathematics Standards." The assessments provide information to parents, educators, policy makers, communities, and businesses about how Alaska's schools and districts are performing. They also provide information to help schools improve and to meet the State Board of Education's Mission, "An excellent education for every student every day." The PEAKS assessments were administered from March 29 to May 14, 2021. The Department of Education and Early Development (DEED) recognizes that the 2020-2021 instruction and assessment environments were very different and provided unique challenges. The Performance Evaluation for Alaska's Schools (PEAKS) reporting for this year will not provide direct comparisons from previous years of assessment.
