This display shows the growth of students relative to other students in the state with a similar scale score in the preceding school year(s). Learn More
If the data is available, the SGP takes up to two prior scores. The school, district and state measure is the sum of the students’ SGP/the number of students with an SGP.
Illinois uses student growth percentiles (SGP) to calculate growth. Proficiency shows whether or not students have mastered a common, high standard; whereas growth recognizes progress toward and beyond the standard, no matter where each student started. Data show that students of all races, income levels, languages, and disability statutes demonstrate growth across the full range. Our rigorous assessments ensure there is more than enough room to measure the growth of even Illinois’ highest achievers.
