### Just a coincidence? That's absurd.

It's a system that causes this pattern to repeat.

NOT what teachers want.

NOT what principals want.

• 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). • The houses with the % of students receiving a Free or Reduced Price Meal is a measure of wealth/poverty.
