The data sgp package provides access to state-level student growth data, including state-specific meta-data. The lower level functions that do the actual calculations (studentGrowthPercentiles and studentGrowthProjections) require WIDE formatted data. The higher level functions that act as wrappers for the lower level functions, such as stateGrowthSummary and stateGrowthProjections, require LONG formatted data. We recommend setting up your analyses with the LONG formatted data as most of the capability built into the higher level functions is designed to work best with that type of data.
The most important step in running SGP analyses is preparing the data correctly. Once the data is in the correct format, most SGP analyses are relatively straightforward. In almost all cases, any errors that arise in SGP analysis revert back to problems with data preparation so it is critical to follow the proper steps for getting your data ready for analysis.
SGP analysis requires student-level data, which is typically stored in tables. Each table contains a record for each student and information about each of their tests in a given content area over time. Each record includes a unique identifier for the student and for each of their test administrations. The SGP package includes a set of tools to facilitate the process of creating this data and making it available for analysis. These tools include a graphical utility for importing and manipulating data, as well as a set of SGP function libraries that are available through the Python programming language.
Using these tools, it is possible to create a database of student-level results and teacher-level performance data that can be used for SGP analyses. The results of these analyses can be displayed on a web-based platform that allows educators to track the progress of their students. Additionally, the SGP package also contains a data set containing anonymized student-instructor lookup tables that can be used to identify teacher-student relationships in a given content area.
A major benefit of SGP data is that the information about student growth is provided at the individual student level, rather than at a school or district level. This information can be extremely useful in helping teachers identify the needs of their students and to plan appropriate instruction. In addition, the information can be useful for administrators and policy makers to monitor the effectiveness of programs, such as those focused on addressing the achievement gap between white and minority students.
SGP data is provided on a web-based platform that is easy to navigate and use. This makes it a convenient resource for a wide range of users. In addition to providing access to SGP data, the site also offers a variety of other educational resources, including information about teaching and learning. The site is free and does not require any registration to use. However, a valid email address is required to view the full database of results. In addition, the site is updated frequently to provide the most recent information about the SGP program.
