2021_2022 School Summative Designations Press Release.pdf

School Summative Designations are based on Multiple Measures

Summative Score Thresholds

Number of Schools by Summative Designation

Distribution of K-8 School Summative Index Scores

Distribution of High School Summative Index Scores

Unit #1 Historical Summative Designation Data

Individual Metrics

Chronic Absenteeism: K-8 = 20%, High School = 10% of the final designation score

Chronic Absentee Rate is the percentage of students that are identified as chronically absent. Students are considered chronically absent as defined in Section 26-18 of the School Code. Medically homebound and hospitalized students are excluded from this calculation. A student is “chronically absent” if they missed 10 percent or more of the school year regardless of excuse.

  • The combined total number of “days absent – unexcused” and “days absent – excused” per student is divided by that student’s length of enrollment.

  • If the sum of absences divided by the length of enrollment is greater than or equal to 0.10 then the student is considered chronically absent.

ELA & Math Proficiency: ELA = 7.5%, Math = 7.5% of the final designation score

ELA and math proficiency is the percentage of students who meet proficiency criteria on the state’s ELA and math accountability assessments.

ELA & Math Growth: ELA = 25%, Math = 25% of the final designation score for elementary only

Student growth percentile (SGP) is a measure of student growth that compares a student’s performance over time to that of their academic peers (e.g., students in Illinois who have the same scale score in the prior year). It includes the current year score and up to two prior years’ scores allowing the growth percentile calculation to represent a true growth trend and not just movement up and down from year to year. Individual student growth percentiles range from 1 to 99. A score of 50 represents average or expected growth each year. These scores are averaged to create a school or student group mean student growth percentile (MSGP).

Science Proficiency: 5% of the final designation score

The science proficiency indicator is the percentage of students who meet proficiency criteria on the state’s science accountability assessments.

  • New science proficiency targets are coming soon

4-, 5-, and 6-year Composite Graduation Rate: 50% of the final designation score for high schools only

The 4-, 5-, and 6-year Composite Graduation Rate is a combination of those years’ Adjusted Cohort Graduation Rate. Adjusted Cohort Graduation Rate is the rate of graduates compared to the total number of students in their 4-year, 5-year, and 6-year cohort for schools and student demographic groups. Graduation Rate is calculated based ESSA High School Graduation Rate guidance. Students are reported at the home school of last enrollment. The cohort is based on the number of students who enter Grade 9 for the first time, adjusted by adding into the cohort any student who transfers in later during Grade 9 or during the next three years and subtracting any student from the cohort who transfers out, emigrates to another country, transfers to a prison or juvenile facility, or dies during that same period.

Climate Survey Participation Score: K-8 = 5%, High School = 6.67% of the final designation score

Climate Survey is a survey taken by all Grade PK-12 teachers and all Grade 4-12 students as required by the ESSA State Plan. The State Board of Education shall administer a Climate Survey, identified by and paid for by the State Board of Education, to provide feedback from, at a minimum, students in Grades 4 through 12 and teachers on the instructional environment within a school, according to 105 ILCS 5/2-3.153.

  • Massac Unit #1 administers the 5 Essentials Survey for this indicator
