Data SGP – Interpreting SGPs and Using Them to Guide Instruction
Written by
SGP Observatory, part of the US DOE Atmospheric Radiation Measurement Program testbed and located on 160 acres southeast of Lamont in Oklahoma. Scientists gather data here in order to improve cloud and radiation models used for climate research.
SGPs show how a student has progressed over time. Each year, their growth is measured against that of academic peers across the state with similar MCAS score histories (i.e. academic peers) who fall within their grade and subject area and who share similar MCAS test history scores as them (not necessarily race/ethnicity or special education peers).
Data SGP uses Damian Betebenner’s latest growth projection software to develop SGPs. His model calculates projections based on historical growth trajectories of past Star examinees and estimates how much growth is necessary to reach or maintain proficiency in grade levels. Our team reviews each year’s projections for accuracy; making sure the percentage of students needing growth fits with expected MCAS pass rates within their state.
SGPs are then used by educators and parents to evaluate a student’s development over time relative to his or her academic peers, as well as to develop their educational plan for next year and make informed evaluation decisions for educators.
OSPI understands that understanding Student Growth Plans and using them to inform instruction may be difficult for many teachers and families, which is why OSPI has provided guidance for administrators, educators, and families on how to interpret SGPs and use them effectively as instructional aids. Our MCAS Growth website contains these SGP Guides for Administrators Educators Families.
Note that SGPs are calculated based on trends in statewide performance; however, percentile rankings change each year and thus any differences between years should be treated with care. Example: Although a student’s 2023 SGP might be higher than 2022 SGP, this does not indicate any greater growth in academic skills. Furthermore, comparison of SGPs between districts cannot always accurately reflect student progress. Every district’s SGPs may differ due to local factors that impact student learning. SGPs cannot be used as an equalizer between schools within a district as they’re calculated using trends within each school; however, SGPs can still help identify areas for improvement and promote student development; the following resources can assist this effort:
