Student Growth Percentiles (SGPs)

Student Growth Percentiles (SGPs) represent one powerful way to quantify the learning of individual students over one or more years. Conceptually, SGPs communicate the degree to which a student has learned in a particular domain, compared to a group of academic peers who had a comparable score on the previous test (or multiple previous tests) in that subject. In order to calculate SGPs, students are grouped with academic peers throughout the state who had comparable score patterns on past tests. Students in each academic peer group are then ordered based on their score on the current year test. Each student then receives a percentile rank, compared to their academic peers. Like other percentile scores, SGPs range from 1-99, where a SGP of 50 indicates that the student demonstrated growth in the content area equal or greater to half of the students with comparable score histories on that subject-matter test.

EVAAS update for Fiscal Year 2025

Since 2018, the State School Aid Act has provided funding for MDE to contract SAS® EVAAS to develop value-added reports to all districts and public school academies. These reports are designed to allow additional insight into student performance on state assessments by including diagnostic information and measures of academic growth made in a selected grade and subject.
 
Additionally, in fiscal years 2023 and 2024, the State School Aid Act funding included requirements that MDE make data publicly available on an external website that provides student growth metrics at the district and school level by grade and subject. The development of the site was provided by the MI-EVAAS value-added reporting platform and the public facing website was launched in March 2024 with state assessment student growth data available through the 2022-23 academic year.

In fiscal year 2025, the State School Aid Act did not allocate funding for MDE to contract SAS® EVAAS to provide value-added reports to all districts and public school academies. Therefore, there will not be reports developed for the state assessments for the 2023-24 academic year.

School district users will find that the login-restricted website will no longer be accessible, however the publicly available external site will continue to display prior reports with state assessment student growth data available through the 2022-23 academic year.

For the most updated state assessment student performance information including the 2023-24 academic year, Michigan districts and public school academies can securely access student growth reports in the dynamic reports section of the MDE Secure Site.  Additionally, publicly accessible student growth reports can be found on MISchoolData.org.
