Data SGP is a set of aggregated student achievement and learning data collected over time, used to help educators and parents better understand the progress made by individual students. It includes individual-level measures like test scores and growth percentiles as well as aggregated data at a school/district level such as class size, attendance rates and graduation rates. This information can be utilized for shaping classroom practices, evaluating school/district performance and supporting broader research initiatives.
The student growth percentile, or SGP, is a measure of a student’s progress on a subject-matter test compared to other students with similar score histories. It ranges from 1 to 99, with higher numbers indicating higher relative growth. A student with a SGP of 50, for example, has a growth score that places them in the top half of students with comparable test history.
A student’s SGP is based on their previous year’s performance on a state test, as well as the performance of other students in their grade, school and district. This data is collected through an online assessment system and is reported in the Star Growth Report. However, a single year of data is not sufficient to provide reliable growth information for all students, which presents challenges when creating SGPs.
This is why it is so important to work with partners that have been vetted and approved by the state. With a vetted partner, you can be confident that the data sgp you are using is valid and unbiased. It’s also essential to use a site that offers live SGP results so you can be sure that the information is up-to-date.
In order to run SGP analyses, you must have access to the sgptData_LONG data set. This data set contains an anonymized panel of 8 windows (3 windows annually) of assessment data in LONG format for 3 content areas (Early Literacy, Mathematics and Reading). The sgptData_LONG is required to generate student projections and requires the following variables: VALID_CASE, CONTENT_AREA, YEAR, ID, SCALE_SCORE and GRADE.
The sgptData_LONG file will be available from the Data Portal shortly, so stay tuned! In the meantime, you can view the student growth reports for the 2014-15 school year by selecting it from the Timeframe drop-down menu.
