The Iowa Tests of Basic Skills (ITBS) are for students in kindergarten - 8th grade. Levels 9-14 are for students from 3rd grade through 12th grade. Sections for levels 9-14 include: Math Concepts and Estimation, Math Problem Solving and Data Interpretation, Math Computation, Vocabulary, Reading Comprehension, Punctuation, Spelling, Capitalization, Usage and Expression, Social Studies, Maps and Diagrams, Reference Materials, Word Analysis (Level 9 only), and Listening (Level 9 only).
The Iowa Assessments test results are used to measure many areas of student growth in local, state, and national performance benchmarks. These assessments are used to support school achievement reporting requirements; they are a predictor of future assessment results, help to create intervention plans and placement decisions, and may be used to evaluate a student's mastery of Common Core State Standards. All of this data, collected, compiled, and reviewed from the Iowa Assessments is useful in measuring current and future performance.
