-29	-21	-25	-14	2	-87.0	-17.4

Simply compute the standard deviation and multiply by 3 and add to the average: 18.6

Simply compute the standard deviation and multiply by 3 and subtract from the average: -53.4

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.

Nevada City Elementary math proficiency

Zero+ meets standard.
