IAR is the current ISBE grades 3-8 ELA/Literacy and mathematics assessment, not the retired Illinois Standards Achievement Test (ISAT). ELA uses two timed units built around literary analysis or narrative writing plus research simulation; mathematics uses three 60-minute units with Type 1, Type 2, and Type 3 item reasoning. Scores are reported in four levels from Below Proficient to Above Proficient, with Proficient cut scores varying by grade and subject. Effective prep should combine text evidence, vocabulary, source-based writing, standard English, multi-step math, proportional reasoning, geometry, data, and modeling practice.

About the IAR Exam
The Illinois Assessment of Readiness (IAR) is the current Illinois statewide assessment for English language arts/literacy and mathematics in grades 3-8. ISBE states that IAR assesses the Illinois Learning Standards incorporating the Common Core. ELA/Literacy asks students to read literary and informational texts, analyze evidence, and respond in writing. Mathematics asks students to solve multi-step problems, reason quantitatively, model real-world situations, and explain mathematical thinking.
Assessment
IAR is Illinois's grades 3-8 English language arts/literacy and mathematics statewide assessment. Official question counts vary by grade, subject, form, and embedded field-test items. The 2026 ELA blueprint uses two sections: a literary analysis or narrative writing task and a research simulation task. The mathematics high-level blueprint lists Type 1, Type 2, and Type 3 items, with 33 scored items per grade form plus embedded field-test items. This practice bank contains 100 original multiple-choice questions aligned to the same ELA and mathematics skills.
Time Limit
ELA/Literacy has two units: 75 minutes each in grade 3 and 90 minutes each in grades 4-8. Mathematics has three 60-minute units in grades 3-8, with non-calculator and calculator sections depending on grade and unit. Schools administer IAR during ISBE's spring assessment window.
Passing Score
No single pass/fail score applies across IAR. ISBE reports four performance levels: Above Proficient, Proficient, Approaching Proficient, and Below Proficient. Proficient cut scores vary by grade and subject; for example, 2025-26 grade 3 Proficient begins at 735 in ELA and 732 in math, while grade 8 Proficient begins at 745 in both ELA and math.
Exam Fee
No direct student fee is listed by ISBE for IAR; the assessment is administered through Illinois public school districts as part of the statewide assessment program. (Illinois State Board of Education (ISBE))

What grades take IAR?
ISBE describes IAR as the state ELA/Literacy and mathematics assessment for Illinois students in grades 3-8.
How long is IAR?
IAR ELA/Literacy has two units: 75 minutes each in grade 3 and 90 minutes each in grades 4-8. IAR mathematics has three 60-minute units in grades 3-8.
What score is passing on IAR?
IAR is not a single pass/fail exam. ISBE reports Above Proficient, Proficient, Approaching Proficient, and Below Proficient. Proficient cut scores vary by grade and subject.
Does IAR include science?
No. IAR covers ELA/Literacy and mathematics in grades 3-8. Illinois science accountability testing is handled separately through the Illinois Science Assessment (ISA).
Are official IAR practice items available?
Yes. ISBE links to official practice test items, released items, the Digital Library, and the Illinois Student Readiness Tool from the IAR page. This bank contains original practice and does not copy secure operational items.
