The goal of data sgp is to provide educators with tools that they can use to understand and interpret student growth trajectories. Students’ growth percentiles indicate whether a student is performing below, at or above the average for their grade and subject area. This information is useful to determine which students are in need of intervention and which are already on track to meet proficiency. In addition, it is important to know which students are likely to achieve or exceed proficiency by the end of their current school year so that teachers can plan accordingly.
Using a combination of statistical methods, data sgp analyses predict the likelihood that a student will achieve or exceed a state’s minimum achievement target (i.e., proficiency). SGP analyses compare a student’s historical performance trajectories with projections from prior years. The result is a range of possible outcomes for the student, including whether the student will reach or maintain proficiency and what their projected scores will be in future years.
Data SGP analyses are based on latent achievement trait models that estimate student progress over time compared against the progression of other students with similar performance histories. These estimates are prone to error, as they can only be approximated from limited amounts of data. To minimize these estimation errors, SGP analyses rely on a two step process: first, estimating student growth standards from limited data and then comparing these estimated standards to actual student outcomes.
Students’ raw MCAS score data is converted to scaled scores and then compared against the growth percentiles of other students with similar MCAS performance histories. These percentiles, which run from 1 to 99, show where a student is ranked relative to the group of students who performed like them in the past. For example, a student with an SGP of 45 means that she grew faster than or at least as fast as the majority of students who performed similarly in the past.
SGP is updated regularly to ensure that a student’s projections are based upon the most recent data available. In the Star growth report, a student’s current SGP is calculated by selecting a previous or current testing window in the report customization timeframe drop down menu.
Educators can use data sgp to identify areas of strength and weakness, inform classroom instruction, and guide district-wide improvement initiatives. The SGP data set also provides a valuable tool for communicating student achievement to parents.
