TECHNICAL REPORTS

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.

IAR ELA Evidence Statements
Evidence Tables and Evidence Statements describe the knowledge and skills that an assessment items or task elicits from students. These are aligned directly to the Common Core State Standards.
Performance Level Descriptors - ELA

Literacy Task Models

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

IAR Performance Level Cut Scores

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.
