2015	2016	2017	2018	2019	Sum	Average
-1	11	10	8	15	43.0	8.6

Simply compute the standard deviation and multiply by 3 and add to the average: 23.6

Simply compute the standard deviation and multiply by 3 and subtract from the average: -6.4

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.

Glendora Unified math proficiency

Zero+ meets standard.
