Georgia Student Growth Model

Georgia educators, parents and students
are hearing a new term in their schools: student growth percentiles. SGPs are
being used in connection with many initiatives such as school
accountability, educator effectiveness and instructional
improvement. So, what are they? In a basic sense, student growth percentiles describe how much
academic progress a student has made relative to other students
across Georgia with a similar achievement history. While
test scores provide a snapshot look at whether or not a student is meeting or exceeding academic expectations at a single point in time, SGPs illustrate how much a student is growing from year to year. Let’s take a closer look. Here is Miss Smith’s fifth-grade class. All of these students participated in state assessments last year in the fourth
grade. Some earned high scores. Others scored lower. Near the middle is Danielle. When
measuring Danielle’s individual growth, it wouldn’t make sense to compare her with
her classmates who had a variety of different prior
scores. So, we’ll look outside this classroom for other students in Georgia
with similar fourth grade scores. These are the academic peers against
which Danielle’s fifth-grade progress will be measured. When Danielle earns a new score at the end the
fifth grade she receives a student growth percentile of 65
which means she grew more than 65 percent of her academic peers. Her academic peers earn different fifth
grade scores which resulted in different SGPs. Some of them demonstrated low growth Some demonstrated typical growth and others demonstrated high growth. Each of the students in Miss Smith’s class has an
academic peer group drawn from students across the state to ensure their growth is being compared to
academically similar students Hannah scored high on this year’s test, but she demonstrated low growth. Even though she is high achieving, she’ll need to be
challenged to keep pace with other high achieving students. John didn’t meet expectations on this
year’s test; however, he demonstrated high growth compared to
his academic peers, and if he continues to grow at this level he is on the path to meeting
expectations in the future. With SGP, all students, low and high achieving, have
the opportunity to demonstrate all levels of growth. That’s the great
thing about SGP. They give us an indication of how much
students are progressing and whether or not they are on the path
to meeting or exceeding expectations in the future. SGPs provide a new insightful way understanding students
academic progress. Used in conjunction with other measures
of student achievement, SGPs are a powerful tool for understanding and improving student performance in
Georgia. For more information about student growth
