A Parent’s Question, What Did Smarter Balanced Scores Tell Us?

I received this question from a parent and I am not sure how to answer it. My husband and I opted out our son from the 11th grade Smarter Balanced test, I have not even seen what the Smarter Balanced scores look like that were sent home to the parents/guardians.

The parent asked, can anyone tell me how the Smarter Balanced scores will help my child improve over the next school year?
