CUSD 4

All public schools that received a summative designation have that designation listed. If an entity does not have a summative designation listed, it is either an entity that does not receive a summative designation, or the school has insufficient size or data to meet the n-size rules for summative designation calculations. The suppression rule for summative designation calculations is a count of at least 20 students per indicator. This suppression rule differs from the reporting suppression rule because they serve different purposes.

Reasons for the Summative Designation are indicated on the following screen. Multiple measures determine which one of four Summative Designations is appropriate for each school.

Exemplary – Schools performing in the top 10 percent of schools statewide with no underperforming student groups.

Commendable – A school that has no underperforming student groups, a graduation rate greater than 67 percent, and whose performance is not in the top 10 percent of schools statewide.

Targeted – A school in which one or more student groups is performing at or below the level of the “all students” group in the lowest performing 5 percent of schools.

Comprehensive – A school that is in the lowest-performing 5 percent of schools in Illinois and any high school with a graduation rate of 67 percent or less.

Student groups used in the calculations include major racial and ethnic identities, students with Individual Education Plans (special education), English language learners, and students from low-income families. In order to protect students’ privacy, a group must include at least 10 students in order to be counted in the calculation of Summative Designations.
