Illinois Assessment of Readiness (IAR
District Performance Measures
District data show evidence of Barrington 220 being a high performing district. The below section reviews performance measures related to academic progress, students (dropout rates and low income), as well as teachers (retention).
Illinois Assessment of Readiness (IAR)
The state assessment and accountability measure administered to students in grades three through eight enrolled in public school districts Illinois students in is the Illinois Assessment of Readiness (IAR). The IAR is used to evaluate student performance relative to the Illinois Learning Standards incorporating Common Core Standards. The IAR is administered in English Language Arts and Mathematics. Scores on the IAR are divided into five broad categorical levels used to report overall student performance that are used to describe how well students met the expectations for their grade level. Students who obtain scores at levels 4 and 5 met or exceeded expectations, demonstrating readiness for the next grade level and are likely to be on track for college and careers. The figure below represents snapshots of performance on the Illinois Assessment of Readiness over time for Barrington School District 220 and the state of Illinois over the last two testing cycles in English Language Arts (ELA) and Mathematics.
The data represented in the figure above demonstrate that a substantially greater proportion of students in Barrington Meet and Exceed Standards than across the State of Illinois, are ready for the next level and are on track for college and careers. Despite the effects of the pandemic, the percentage of students obtaining scores in Levels 4 (Meeting) and 5 (Exceeding) in 2021 in Barrington remains higher than the pre-pandemic achievement of students across the state of Illinois in both English Language Arts and Mathematics.
