AK STAR Math Grade 9 · Put your knowledge to work in context.

AK STAR - the Alaska System of Academic Readiness - is Alaska's statewide assessment system for students in grades 3–9 in English language arts and mathematics. For a Grade 9 mathematics student, it is the final grade level in that 3–9 span. The Alaska Department of Education and Early Development (DEED) partnered with NWEA to build a balanced system that connects fall and winter MAP Growth interim assessments with the Alaska spring summative assessment. The stated goals are to streamline testing, increase coherence between interim and end-of-year tests, and give educators, students, and families meaningful information about strengths and areas of need. The AK STAR Math Grade 9 case studies are 5 cases and about 2,353 words.
