Just a coincidence? That's absurd.
It's a system that causes this pattern to repeat.
THIS chart shows what the
follow-the-schedule method wants.
NOT what teachers want.
NOT what principals want.
NOT what parents 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.
