Parent & Teacher Resources

Family Portal

The Parent Portal has been renamed the Family Portal. The Illinois Assessment of Readiness Family Portal is for parents/guardians to have online access to their child’s performance on the IAR tests for English Language Arts/Literacy and Mathematics.

The IAR Family Portal is expected to become available for use at the end of October 2025.

Career and College Readiness Resources

The Illinois Assessment of Readiness for English language arts and mathematics for Grades 3-8 has been linked with the Lexile and Quantile Framework to support the development of students and determine if they are on track to graduate college and are career ready. Using the Lexile and Quantile score included on the Individual Student Report, parents and teachers can utilize the enhanced resources, tools, and capabilities through our state partnership with MetaMetrics.  
  • Lexile and Quantile Hub
    This online platform provides you with easy access to more than a dozen new and enhanced reading and mathematics tools.
  • Lexile and Quantile Growth Planner
    This planner helps parents and teachers to identify the reading and math requirements needed for a desired career for students and use them to inform goal-setting.
  • Lexile and Quantile Career Database
    This helps parents and teachers to compare and describe the reading and math requirements of career interests for students.

Test Design

English Language Arts

The ELA/L summative assessment is available in Grades 3 – 8. Students read and analyze passages from real, authentic texts – both fiction and nonfiction – as well as multimedia. Students then draw upon what they’ve learned from these passages and multimedia, using that knowledge to respond in writing. These skills are critically important for students in college and the workplace.

MATHEMATICS

The mathematics summative assessment is available in Grades 3 – 8. Students solve multi-step math problems that require reasoning and address real-world situations. This requires students to reason mathematically, make sense of quantities and their relationships to solve real-world problems, and show their understanding. Many previous assessments focused mostly on rote procedure only.

IAR Performance Levels

Results on assessments are reported for ELA and Mathematics according to five performance levels that delineate the knowledge, skills and practices students are able to demonstrate:
  • Level 1: Did not yet meet expectations
  • Level 2: Partially met expectations
  • Level 3: Approached expectations
  • Level 4: Met expectations
  • Level 5: Exceeded expectations


Notice: Please be aware that ISBE is engaging in a unified standard-setting across all grade levels and content areas of our general education content assessments (ELA, math, and science). As part of that work, educator committees are currently working to draft new PLDs in each content area. More information is available and being updated regularly on the ISBE Better Systems for Better Outcomes webpage.​
