2015	2016	2017	2018	2019	Sum	Average
53	59	57	55	56	280.0	56.0

Simply compute the standard deviation and multiply by 3 and add to the average: 62.0

Simply compute the standard deviation and multiply by 3 and subtract from the average: 50.0

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.

Irvine Unified math proficiency

Zero+ meets standard.
