What is Data SGP?

Data SGP is a database that contains information about student assessment results. Teachers and administrators use this information to determine how well students are progressing academically and help them pinpoint areas for improvement. This database also helps them identify the best methods for evaluating their students’ performance.

SGP analyses use two steps to compensate for estimation errors: 1) an estimate of a student’s prior test score, and 2) comparison between a student’s current performance and their estimated previous performance. To facilitate these calculations, SGPdata packages contain lower level functions and wrapper functions that simplify operational SGP analysis source code.

The sgptData_LONG data set contains assessment data in LONG format for 8 windows (3 windows annually). It includes a variety of variables including VALID_CASE, YEAR, CONTENT_AREA, ID, SCALE_SCORE, GRADE and ACHIEVEMENT_LEVEL (required if running student growth projections) and demographic/student categorization variables.

In addition to these variable, the sgptData_INSTRUCTOR_NUMBER data set contains an anonymized, student-instructor lookup table that allows for a single teacher to be associated with multiple students. This is useful when comparing student-by-student growth trends over time for the same instructor. The sgpData_INSTRUCTOR_NUMBER table is available to all students with a teacher assigned to them in a given window.

In order to calculate a current SGP for a student, it is necessary to have at least two tests from different windows. SGP utilizes the historical growth trajectories of the Star examinee to map out what range of potential growth a student’s current trajectories will lead to, including the minimum amount of growth required to reach/maintain proficiency. This information is used to predict what the student’s score will be on their next assessment.

SGP is a powerful tool that can be used to provide accurate predictions about students’ future performances. However, it is important to remember that this tool does not replace the need for a high quality classroom environment and instructional practices. The sgptData_LONG and sgpData_INSTRUCTOR_NUMBER sets of data are helpful resources for a variety of educational purposes, including identifying the most effective instructional practices for each student. The sgpData_INSTRUCTOR_NUMBER dataset can be especially beneficial for teacher training, as it can be used to analyze teacher performance and evaluate the effectiveness of their instruction. This will in turn help them to improve their classroom practices. In the long run, this can help to maximize the impact of the SGP tool. This is an important goal for all educators. By utilizing the tools provided by SGP, teachers can make better decisions about their students’ needs and provide them with the support they deserve.
