Data sgp is an important tool for teachers and administrators. It provides information about how students are progressing on state assessments. The information can be used to determine if a student has shown more or less growth than their academic peers. It can also be used to assess whether a student has surpassed their expectations for growth. However, gaining access to this information can be difficult. There are some resources available that make the process much easier. One of these resources is the SGP Pools.
The SGP Pools are a collection of data sets that provide an excellent opportunity to access the latest SGP results for students. This information is compiled from district course roster submissions to SMART that are completed during the summer after each year’s statewide assessment. This information is then used to create the SGP scores that are reported in the fall and spring. The SGP pool data sets contain information about how a student performed on a particular test in a given window.
To calculate a student’s SGP, the test performance of that student is compared to their academic peers. A student’s academic peers are those students in the same grade and subject area that had statistically similar assessment score paths in previous years. The SGP percentile for a student is defined as how many of their academic peers achieved higher or lower test performance than the student.
SGP is a valuable tool for educators because it measures a student’s relative performance in comparison to their academic peers. It can be difficult to assess a student’s growth based on their individual assessment history alone, as each student’s score path is unique. SGP is designed to eliminate this difficulty by comparing the performance of all students in a given academic context.
The SGP Pools allow educators to access this data in two formats. These formats include Window Specific SGP and Current SGP. The difference between the two formats is that Window Specific SGP only reports SGP for students who have taken at least two tests within a given testing window, while Current SGP can be calculated for any student who has participated in at least one test from any testing window in their career.
Ultimately, the goal of SGP is to access and aggregate large amounts of data that would otherwise be difficult to collect and share. While research consortia and full community databases (such as Genbank, EarthChem, etc.) aggregate and make available a great deal of information, they are not meant to replace the need for researchers to collaborate with each other on interesting and relevant questions in Earth science.
There are several considerations when deciding how to format data for use with SGP analyses. The SGP package provides functions, called wrapper functions, that simplify the coding required for these analyses. The lower level functions, studentGrowthPercentiles and studentGrowthProjections, require WIDE formatted data, while the higher level wrapper functions support LONG formatted data. If you plan to run SGP analyses operationally year after year, it is recommended that you format your data in the LONG format as it has numerous preparation and storage advantages over WIDE formatted data.
