What is Data Sgp?
Data sgp is a set of anonymized assessment data in long format for 3 content areas. The data set includes assessment data from 5 years for each student. The first column, ID, provides the student unique identifier and the next five columns (GRADE_2013, GRADE_2014, GRADE_2015, GRADE_2016, and GRADE_2017) provide the grade level for each assessment score. The scale scores are associated with each assessment. These values are standardized and aggregated to generate student growth reports for each student.
Using wide-format data like sgpData with the SGP package is, in general, straight forward. However, it is important to read the SGP data analysis vignette for more comprehensive documentation on how to use sgpData (and WIDE data formats in general) for SGP analyses.
A key feature of the sgpData set is that it includes lookup tables for teacher/student associations. This makes it possible to analyze student growth by teacher, class, school, and district. The sgpData_INSTRUCTOR_NUMBER table is an anonymized lookup table that provides instructor numbers associated with each student’s test record. A student could be taught by multiple instructors in a single content area for a given year, so the sgpData_INSTRUCTOR_NUMBER variable allows us to identify those teachers by using the student identifier (ID).
The sgptData_LONG data set contains the same information as the sgpData data set except it includes a student demographic variables table that can be used for demographic/student categorization purposes when creating student growth aggregates with the summarizeSGP function. This data set also contains a student-teacher association lookup table that can be used to associate teacher names with students by using the student identifier (ID).
This data set provides a powerful tool for analyzing student performance and progress in our state. It will help to identify strengths and weaknesses in the education system and provide insight into how students are learning. In addition, it will help to improve student achievement by providing valuable feedback to educators and families. This is an important step in our state’s effort to provide every child with the best possible educational experience. We look forward to continued collaboration with partners throughout the country as we work together toward this common goal. We are confident that the data and tools provided by this release will make it easier than ever for educators to analyze and interpret student growth results. We hope that these new capabilities will encourage the development of additional tools to support the ongoing evaluation of our students and schools. We would also like to thank our many collaborators for their commitment and hard work in developing these new SGP analyses and tools. We are eager to hear from you about your ideas for future improvements to the SGP toolkit. We are happy to provide support as needed.
