Simply compute the standard deviation and multiply by 3 and add to the average: 27.4

Simply compute the standard deviation and multiply by 3 and subtract from the average: -14.6

NOT what school board members want.

NOT what superintendents want.

But that's not what it "wants"...and it's not a coincidence this pattern repeats (repeatedly).

• Any result above zero is proficient; below is not proficient.
