Chaffey Joint Union High math proficiency
Zero+ meets standard.

• Any result above zero is proficient; below is not proficient. • There is a 99% chance that results will remain the same in coming years, which is to say, between the Upper and Lower Control Limits (the gray lines).

Students would perform better the more years in school IF the follow-the-schedule method wanted that.

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.
