Data SGP gives insight into student achievement and growth with longitudinal test score data, making this metric invaluable for informing instruction, evaluating teacher/student performance assessment and supporting educator evaluation systems. Calculated using latent achievement trait models with historical assessments data in order to establish growth standards that reduce estimation error, this metric is extremely valuable in making instructional decisions and supporting educator evaluation systems.
Students with higher data sgp values typically demonstrate greater academic improvement than students with lower data sgp values, which suggests they are learning more than their counterparts. Teachers can use data sgp to identify areas for classroom improvements and offer extra assistance so their students are making strides towards meeting their state and district goals.
Michigan Department of Education (MDE) strongly suggests that districts begin using data sgp for educational purposes prior to adopting it for high-stakes educator evaluations in 2015/16. This will give districts three years to familiarize themselves with this new metric and work with it before using it in high-stakes evaluations of educators.
To gain a clearer picture of data sgp’s operation, consider this hypothetical example: If a student’s scale score on an M-STEP test rose by 70 points this year compared with last year, their data sgp would indicate they are now scoring within the 75th percentile among similar students who took last year’s exam.
Teachers will now have access to SGP results from grades 4th through 11th in the BAA Secure Site on student profile pages and growth dashboards for individual students from grades 4th to 11th. Educators and parents alike will find it easier than ever before to compare student progress across years and tests.
Additionally, SGP percentages for each student have been displayed as relative percentiles rather than absolute numbers per MDE’s recommendation in order to distinguish more clearly between high and low relative performance. Percentiles range from one to 99 and should be read similarly to percentile ranks on standard achievement tests; lower numbers signifying lower relative performance while higher numbers signifying greater performance.
Macomb and Clare-Gladwin ISDs have developed interactive data tools to allow educators to easily access growth data for their students. Educators will be able to use these interactive data tools to generate personalized graphs that depict student progress over time for every assessment report, compare data between assessments in an entire testing window, as well as gather growth information for the Badger test.
These tools were designed to work with the new sgpData_LONG files, which have been optimized to provide efficient access to each student’s embedded SGPstateData meta-data. More information and available resources for these tools can be found here.
