Outstanding Student Performance


The Illinois Standards Achievement Test (ISAT) is one of several assessments District 27 uses to monitor student learning and overall progress. The ISAT is a large-scale measure that demonstrates how our students meet the No Child Left Behind (NCLB) federal law. It is also used to compare out students’ performance against the Illinois Learning Standards.

In 2012, ISAT performance was measured at six grade levels and in three key subject areas. In the spring, students in grades 3-8 took the ISAT in reading and math. Students in grades 4 and 7 also took the ISAT in science.


NWEA assessments are national, adaptive assessments used to measure students’ progress or growth in school. In addition to using the data at the individual student and classroom level, the District monitors the grade level mean score (RIT score) and national percentile standing for each subject and grade level.
