Iowa Algebra Aptitude Test™

Iowa Algebra Aptitude Test™ (IAAT™), Fifth Edition, assesses students’ readiness for Algebra I, including any additional support and intervention they may need to become successful in the algebra classroom. IAAT™ is a group-administered, 50-minute algebra placement exam designed for grades 7 and 8 but is suitable for accelerated students in lower grades and high school and junior college students.

The assessment contains questions in four general areas:

  • Pre-Algebraic Number Skills and Concepts – How well students understand the mathematical skills and concepts necessary for success in an algebra course
  • Interpreting Mathematical Information – How well students can learn new materials presented in graphs or text
  • Representing Relationships – Students’ abilities to find formulas for numerical relationships
  • Using Symbols – How well students understand important symbols of algebra and how they are used

The highest achievable standard score (SS) is 200 which equates to the 99th percentile. The chart below will assist you in converting the standard score to a percentile rank. A percentile rank of 75 means that the student scored nationally better than 75% of the students who took the assessment.

Please remember that the IAAT is a readiness assessment. Student scores are reflective of how your child compares to other students of his/her age and grade, and do not reflect a mastery of algebra concepts.
