Median Student Growth Percentile (mSGP) Conversion Chart
As one of several evaluation measures under AchieveNJ, the mSGP is converted to a 1.0 - 4.0
score, then weighted appropriately and included along with other components to tabulate the
final evaluation rating.
The New Jersey Department of Education undertook a careful process to create a scale that
translates mSGP scores from a 1 - 99 scale to the 1.0 – 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 - 99 scale will translate into an
effectiveness rating from 1 - 4, the Department has provided the chart below:
