Data Sgp is a statistical package used to compute student growth percentiles and projections/trajectories from large scale longitudinal education assessment data such as standardized tests, portfolios or grading scales. It is an open source package which is useful in many evaluations such as tracking student performance over time; assessing educator effectiveness; or evaluating education policies.
The SGP package supports wide-format datasets, which are easier to manage than traditional narrow-format data sets. When working with such data sets however, some important considerations need to be kept in mind when using the package; the SGP vignette page offers further instructions.
SGP also facilitates analysis of student growth over time, making it especially helpful for teacher and leader key effectiveness systems such as TKES/LKES. Such systems require educators to understand their own growth and development as compared with that of other teachers within their district and state.
To perform these analyses, the SGP package employs a student growth model which enables users to estimate Student Growth Percentiles (SGPs) for every individual in their sample and compare these SGPs against population averages to help teachers and administrators identify which individuals are making progress and those who need additional support.
Making the choice between WIDE or LONG format data formats is often a complex one with major consequences on what types of analyses can be performed. For most applications, it is advised that higher level SGP wrapper functions like studentGrowthPercentiles and studentGrowthProjections be utilized with LONG data format as they offer many preparation and storage advantages over WIDE data formats. This recommendation holds especially true if conducting such analyses year after year – the LONG data format offers numerous preparation and storage advantages over its WIDE counterpart.
