Median Student Growth Percentile Conversion Chart
As one of several evaluation measures under AchieveNJ, the mSGP is converted to a 1.0 to 4.0 score, then weighted appropriately and included along with other components to tabulate the final evaluation rating.
The New Jersey Department of Education (NJDOE) undertook a careful process to create a scale that translates mSGP scores from a 1 to 99 scale to the 1.0 to 4.0 rating required by AchieveNJ. This process began with an examination of pilot data and extended to additional research and consultation with other states using similar measures to identify conversion approaches. Then, we conferred with the Department’s Technical Advisory Committee and other external experts to build a scale that is both transparent and fair to teachers while maintaining high expectations for student learning.
In order for educators to understand how their score on a 1 to 99 scale will translate into an effectiveness rating from 1 to 4, the Department has provided the mSGP Conversion Chart below:
