School Summative Designations

Unit #1 Historical Summative Designation Data

The graphs below illustrate the percentage of students meeting proficiency standards in ELA and math in each school district across Illinois. The distributions of these percentages in 2023 and 2024 are captured under the grey and purple curves respectively. The state median is noted for each year as well. The vertical lines illustrate the percentage of students meeting proficiency each year in Massac Unit 1.

Massac Unit 1 also received a percentile rank report.  Percentiles are calculated by ranking all Illinois school districts on individual indicators.  A percentile rank of 60 would indicate that the district performed the same as or higher than 60% of all school districts in the state of Illinois on a particular indicator.  A percentile rank of 50 is the statewide average for all schools on a particular indicator. Massac Unit 1 received the following percentile rankings for 2024:

Massac Unit 1 schools performed the same or better than 76% of all Illinois schools in ELA Proficiency, 77% of all Illinois schools in Math Proficiency, 68% of all Illinois schools in Science Proficiency, 75% of all Illinois schools in ELA Student Growth, and 55% of all Illinois schools in Math Student Growth.

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.


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.

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.
