Data SGP

Data SGP is an analysis tool for the statistical software R, an open source program. It is designed specifically for educational assessment data, but has the flexibility and power to be used with any type of statistical or data analysis. It can be run from a command line or as a Python script. It can be used by individuals or a team.

Data sgp provides the ability to analyze and visualize student growth data. It can also be used to predict future performance by comparing students with similar baseline profiles. The tool can be used to identify students who are likely to fail and to provide targeted interventions for these students. Data sgp can also help districts articulate and measure achievement targets/goals by showing how much students must grow to achieve them.

It is important to note that SGP analyses are only as good as the data they are based on. As such, a great deal of time is spent on data preparation for SGP analyses. Any errors that occur during an SGP analysis usually revert back to problems with the data or data preparation. As such, we highly recommend following the recommended steps for preparing your data for SGP analyses.

The sgpData data set is an anonymized, structured data file that contains the student assessment records in the formats required for SGP analyses. It includes a number of fields that are required for SGP analyses, including the unique student identifier and the scale scores associated with each assessment in each year (SS_2013, SS_2014, SS_2015, and SS_2016). It also contains the student-instructor lookup table sgpData_INSTRUCTOR_NUMBER, which allows for the association of students with instructors through their unique identifiers and for the assignment of students to a single instructor for a particular content area in a given year.

As mentioned, the sgpData data set is an invaluable resource for districts interested in analyzing their own students’ data with SGP. The sgpData_INSTRUCTOR_NUMBER field, in particular, is an extremely useful feature that allows districts to connect students with their instructors by matching the unique student identifier with the instructor of the individual’s test record. As such, it is essential that the sgpData_INSTRUCTOR_NUMBER table be provided to students and teachers in formats compatible with SGP analyses.

Please refer to the SGP data analysis vignette for more detailed information on how to use the sgpData data set. Also, please consult the SGP data analysis documentation if you have questions about any of the functionality in the SGP package. It is important to remember that the lower level SGP functions, such as studentGrowthPercentiles and studentGrowthProjections, require WIDE formatted data. The higher level wrapper functions, however, utilize the LONG data format, which offers numerous preparation and storage benefits. If you are planning on running any other analyses than the simplest, one-off SGP analyses, we strongly recommend formatting your data in the LONG format.
