Simply compute the standard deviation and multiply by 3 and add to the average: 68.4

Simply compute the standard deviation and multiply by 3 and subtract from the average: 32.4

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.

Mill Valley Elementary math proficiency

Zero+ meets standard.
