How to Analyze Student Growth Progression (SGP) Data
The SGP metric, which stands for Student Growth Progression, is an indicator of relative academic growth over time. It is calculated by comparing the assessment scores of a student to those of their academic peers. It can be useful in informing instruction, assessing student performance, and identifying areas where additional support may be needed.
SGP scores are reported on a 1-99 scale, with higher numbers indicating greater relative growth than lower ones. The metric can also be used to assess the overall performance of a school or district. For example, a SGP score of 75 indicates that a student has made approximately 75 percent of the progress expected of him or her.
Using SGP data to make predictions is easy, and the results can be analyzed over time. The analysis of this data is based on several factors including the student’s demographic information, grade level, test results, and overall score. It can also include a comparison of student scores by gender, race, and disability status.
The sgpData spreadsheet is a great tool for educators to view SGP data in a very detailed manner. It is available by selecting a specific student in the SGP summary report and choosing the “SGP Data” tab. It displays the SGP scores for a student over the course of five years. The first column, ID, provides the unique student identifier. The next 5 columns, SS_2013, SS_2014, SS_2015, SS_2016, and SS_2017, provide the student’s assessment score for each of the five years they have been tested.
In addition to SGP, sgpData can also be used to calculate other indicators of student achievement such as MAP and ACT composite scores. This makes it possible to compare students across schools and districts, and to identify patterns in a student’s performance over time. These insights can be used to inform instruction, identify areas where further support is needed, and improve student outcomes.
While sgpData is designed to work with LONG formatted data, it is often easier to manage in the WIDE format. For this reason, it is recommended that users of sgpData consult the SGP data analysis vignette for more comprehensive documentation on how to use sgpData and wide formatted data for SGP analyses. In particular, the vignette offers examples of sgpData usage and explains how to use it with a variety of higher level functions.
