Data sgp is a set of academic assessments that can help teachers identify which students are struggling and provide them with the support they need to improve their grades. This data can also be used to predict how much a student will progress over time. In addition, it can be useful for educational policymakers and administrators.
While the previous section establishes that true SGPs are correlated across math and ELA and are related to student background characteristics, our results go further. Specifically, we show that even though true SGPs can be estimated from standardized tests with no measurement error at the individual level, such estimates suffer from large estimation errors at higher levels of aggregation (e.g., teacher and school).
This is evident in the scatter plot of RMSE for conditional mean estimators of e4,2,i on the vertical axis and scale score on the horizontal axis. For example, at the teacher level, the RMSE for conditioning on only prior math scores is nearly double that when conditioning on both current and prior math and ELA scores. At the school level, a similar result holds for aggregating math and reading scores into one composite.
Our results further suggest that interpreting aggregated estimated SGPs as indicators of teacher effects may be problematic. For example, if the purpose of aggregating estimated SGPs is to evaluate teacher effectiveness, the relationships between true SGPs and student background characteristics can create substantial bias. This source of bias could be eliminated by modeling the student-level data with a value-added model that regresses test scores on teacher fixed effects, prior test scores, and student background variables.
The SGP package includes exemplar WIDE and LONG format data sets to assist in performing these analyses. The sgpData_WIDE and sgpData_LONG datasets contain the same information, but sgpData_WIDE contains the information in tabular form whereas sgpData_LONG provides it in an array format with rows representing individual students and columns for each assessment window. The lower level functions in the SGP package use WIDE data formats, while the higher-level wrapper functions utilize the LONG data format for all but the simplest, one-off analyses.
