A Brief Introduction to Student Growth Analyses in Indiana Dr. Damian Betebenner Center for Assessment Indiana State Board of Education Meeting Gary, Indiana October 2nd, 2019

History • Indiana has been at the forefront nationally in the use of student growth measures. • The Center for Assessment has been working with Indiana for 10 year in the development and support of the Indiana Growth Model. • Indiana has supported student growth analyses in ELA and Mathematics across 2 assessment transitions. • The most recent transition from ISTEP to ILEARN occurred from 2018 to 2019 4/30/19 SGP SEM for 2018 EOG/EOC Testing 2

Growth Model Approach • The current growth model used by Indiana calculated an individual student growth percentile (SGP) for each student, which is then associated with a point value that is averaged across all students for a given school. • An SGP ranges from 1-99 and is uncorrelated with the starting point of a student so that each student, regardless of where they start has the same chances of demonstrating the entire range of student growth. 4/30/19 SGP SEM for 2018 EOG/EOC Testing 3

Growth Model Approach • Based upon work of the Accountability System Review Panel, a growth-to-proficiency approach was recommended. • Target ranges are a key component for establishing points within the growth to proficiency table because these ranges create the thresholds for which points are to be assigned. • The target ranges summarize the observed growth associated with low, standard or high movement relative to Indiana’s achievement levels. 4/30/19 SGP SEM for 2018 EOG/EOC Testing 4

Growth Model Approach • The point values associated with the target ranges allows IN to establish policy priorities related to student growth at different levels of student achievement. • For example, low achieving students can be assigned higher weights for exemplary growth in an effort to reward student growth for that population. • Based upon Indiana’s new performance standards, the growth-to-proficiency table recommended for use is as follows 4/30/19 SGP SEM for 2018 EOG/EOC Testing 5
