Data SGP is an essential component of the SGP package for analyzing student growth data. This package features several functions to generate student aggregates based on assessment results as well as predefined report templates that can be tailored specifically for individual school districts or regional education agencies (R.E.A). Furthermore, sgptData_LONG data set contains eight windows (3 windows annually) of assessment data in LONG format from three content areas, similar to its Wide counterpart except without demographic or teacher categorization variables.
SGP functions work with both WIDE and LONG formatted data; however, for operational analyses that you want to repeat every year it may be more efficient and robust to use higher level wrapper functions (studentGrowthPercentiles/projections) with LONG data formats; this is particularly true if your database uses relational schema.
Working with LONG data requires some extra consideration when importing it into R scripts. First, you will need to understand the differences between WIDE and LONG formats before selecting an ideal format to maximize how many SGP analyses can be run with it – this is particularly relevant if creating individual student growth and achievement plots.
As well as SGP function wrappers, there is also a lower-level wrapper function which can help import and convert LONG data sets to WIDE formatted ones. This function may prove particularly helpful to newcomers who wish to perform advanced analysis with LONG data sets.
SGP is an incredibly effective tool for analyzing student growth data, so much so that many school systems have adopted it as the main student assessment system in their district. SGP provides many features that make creating reports and plots to visualize student performance easy, while offering educators statistical tools for making informed decisions about instruction. SGP provides an excellent cost-cutting alternative to more traditional student assessment systems; annual costs associated with SGP implementation for large districts often fall within 1 percent of annual student assessment costs. SGP provides an attractive option for districts looking to reduce administrative costs by cutting the expense associated with traditional student assessments.
