SAVE means that this case has been saved to your group’s record, but will not be SENT to the ACR until reviewed and submitted by your group administrator. This provides an opportunity for any score of 2b, 3, and 4 to be reviewed prior to submission to the ACR.  If you have scored a case a 2b, 3 or 4, you will need to enter “Comments” before being able to save.
