Idaho Standards Achievement Tests (ISATs)

The ISAT summative assessment is an important component of the statewide student assessment system as stated in the board rule 08.02.03-Rules Governing Thoroughness. The ISAT tests are administered to students in grades 3-11 to provide ongoing monitoring of individual, school, district, and state progress. One component of the ISAT required for high school graduation is the 10th grade assessment in English Language Arts / Literacy and Mathematics. Proficiency on the 10th grade ISATs verifies that an Idaho student has met Idaho Core Standards in these content areas.

Academic proficiency is more than test scores. Competency in all academic areas is the goal for every child.

Components of the ISATs

The ISAT is composed of English Language Arts/Literacy and Mathematics tests for grades 3-11 that address the Idaho Core Standards and Science tests for grades 5, 7, and 10, which address the Idaho Science Standards. A variety of item types are used to assess what a student knows and what they can do with that knowledge. The items address a variety of skill levels, from short-term recall of facts to skills and problem solving.

The ISAT summative assessment is administered during the last 8 weeks of the school year. It consists of two parts: a computer adaptive test and performance tasks taken on a computer. The assessment:

  • Accurately describes both student achievement and growth of student learning as part of program evaluation and school, district, and the state accountability system;
  • Provides valid, reliable, and fair measures of students' progress toward, and attainment of the knowledge and skills required to be college- and career-ready; and
  • Capitalizes on the strengths of computer adaptive testing-efficient and precise measurement across the full range of achievement with quick turnaround of results.
