Data Stewardship Plan (DSgp) is an umbrella term that encompasses managing data as an enterprise asset and using it securely, efficiently, and cost-effectively prior to disposal. This encompasses every stage from collection through storage usage oversight – as well as informing and empowering relevant personnel for use of the data collected – before its disposal. DSgp may be difficult to implement but essential for data-driven organizations.
SGP uses longitudinal student assessment data to generate statistical growth plots (SGPs). An SGP measures relative student progress relative to academic peers using an established growth standard derived from prior test scores and covariates, providing insight into both progress as well as teacher effectiveness.
SGPs were developed with educators in mind; unlike Michigan’s current educator evaluation system, SGPs are designed to be transparent and accessible. Teachers can download the “Student Data File” on the BAA Secure Site under “Reports,” import it into one of Macomb or Clare-Gladwin ISD’s data tools to explore data more easily while creating reports that can be shared with parents. While using tools for learning about SGPs may be beneficial, we strongly advise districts only use them for that purpose versus using them for educator evaluation purposes.
The sgpData vignette presents an example of a longitudinal panel data set in WIDE format suitable for SGP analyses. This dataset contains five years’ worth of vertically scaled assessment scores with ID as an identifier, GRADE_2013 through GRADE_2016 being grade levels and scale scores respectively for every assessment conducted; finally SS_2013 through SS_2016 provide scale scores related to these assessments.
An SGP for any student can be determined by comparing their most recent assessment score with the average scale score for students at their same grade level and content area in five previous assessments. It can then be compared with an appropriate growth target, such as percentage of academic peers or percentile rank; higher SGPs indicate better student performance while lower ones suggest greater fall behind academic peers; this information allows educators to target areas for improvement and ultimately promote student achievement and success.
