The data sgp package is designed to be easy to use. The analysis process is straightforward and consists of two steps, data preparation and running the SGP calculations.
SGP is a student growth percentile that describes a student’s test score growth compared to other students with similar prior test scores (their academic peers). It helps us fairly compare students who enter school at different levels, and it allows us to demonstrate progress and academic growth for any student.
Percentiles are familiar to most teachers, but they’re not always easy to understand or calculate. The SGP package provides several tools to assist with this task.
sgpData_INSTRUCTOR_NUMBER is an anonymized, student-instructor lookup table that provides insturctor information associated with each students test record. This information can be useful in many ways, such as identifying teachers in a district who may not have been previously identified, or determining whether students are receiving the appropriate curriculum.
Insturctors can be found in multiple places throughout the district and can include both classroom teachers and administrators. The sgpData_INSTRUCTOR_NUMBER data set also provides information on the teachers’ qualifications, including their certification.
When using the SGP package, it is essential to follow these guidelines. Failure to do so could result in inaccurate calculations.
The SGP package uses WIDE formatted data for the lower level functions that do the calculations, such as studentGrowthPercentiles and studentGrowthProjections. However, the higher level functions (wrappers for the lower level functions) require LONG formatted data.
This is because the higher level functions rely on the data supplied by the user. The user must supply the data in a format that is easy to read and manipulate by the SGP program.
Once the data is prepared properly, running SGP calculations is simple and straightforward. Any errors that arise during the analysis process usually revert back to issues related to data preparation.
The sgpData_INSTRUCTOR_NUMBER and sgpData_INSTRUCTOR_SUBJECT_ID data sets are annotated for use by instructors in the SGP package. They provide an easy-to-use way to identify teachers in the district who may not have been previously identified.
While this information is important for teachers to have access to, it’s not a substitute for identifying and working with instructors who are qualified to teach the content at hand. This is especially true when working with students who have special needs or learning disabilities.
Insturctors can help students overcome obstacles and find success in the classroom, but they are not a substitute for a teacher who has a strong teaching skill set. It is also important to remember that a student’s academic performance can change over time as their strengths and weaknesses shift.
It is essential to have the information about teachers available for each student at all times so that students can have access to teachers who are able to address their academic needs. This data can be particularly helpful in ensuring that students are not being pushed too hard by teachers who are not able to meet their individual needs.
