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:
