ISAT Science Grade 5 case studies
ISAT Science Grade 5 · Put your knowledge to work in context.
The ISAT Science assessment for Grade 5 is Idaho's standards-based science test for elementary students, given as part of the state's assessment and accountability system. It is intended for fifth-grade students in Idaho public schools and is usually taken near the end of the school year, after students have had sustained instruction in the grade-level Idaho Content Standards for science. The test is multiple choice and samples the four strands that organize elementary science in Idaho: physical sciences, life sciences, Earth and space sciences, and engineering design. Items ask students to recall core ideas, read simple data tables and diagrams described in the item text, and apply reasoning to familiar situations rather than recite isolated definitions. The ISAT Science Grade 5 case studies are 5 cases and about 3,068 words.
