I wouldn’t recommend that.
MAS (Maximum Achievable Score) is a misnomer, in a sense. Even though it may be set to a 3.0 you still CAN give 4.0 score. Think of MAS as the Goal Score. And it is important not to set a goal of 4 if that’s not the goal because Empower will then count a 3 as less than expected when it does certain calculations and the student status will show that they didn't meet expectation.
