What is Data SGP?
Data sgp is a database of growth percentiles and projections produced by Wyoming’s Star Assessment system. It allows educators, parents, students and schools to track a student’s progress relative to other students in the state. The information is calculated by analyzing the growth trajectories of students who took similar Star assessments in different years.
A student’s growth percentile tells them how much more or less they grew in academic skills from one year to the next compared to their “academic peers.” A student’s academic peers are students who have the same MCAS score history as the student, and who belong to similar demographic groups such as race/ethnicity, income, educational programs (e.g., sheltered English immersion) and multilingual learning. A student’s SGP is calculated using up to five years of test score histories. For example, a sixth grader’s SGP will be based on the student’s performance from the Badger Exam and up to two previous tests.
If a student’s SGP is 84, that means the student grew in academic skills more than 85% of their academic peers. If a student’s SGP is 25, this means the student grew in academic skills less than 25% of their academic peers.
Educators can use this data to identify what needs to be improved and how students are doing with their growth. Educators can also use this data to analyze the growth of their school or district, and to help inform decisions about teaching, learning and accountability.
The state’s SGP website provides an interactive data visualization tool that allows stakeholders to view and interpret data sgp for individual students, schools, districts and subgroups. The tool includes a dashboard that displays individual student SGPs, as well as aggregated SGPs for grades, schools, districts and subgroups. Each report has an explanation of the key indicators displayed, as well as links to more detailed information.
SGPs are a useful tool for teachers and administrators, but they must be considered along with scaled scores and achievement levels to gain a more complete picture of student learning. As a result, differences between SGPs from one year to the next should be interpreted with caution. Generally, differences of 10 points or more should be considered significant. Likewise, the average SGP statewide will fluctuate from year to year because the average involves a smaller sample of data. However, the mean SGP for a particular district or school will remain stable because it is based on long-term data. For more information on how to read and interpret SGPs, please see one of our stakeholder-specific guides for administrators, educators or families.
