NOT what parents want.
Horizon Elementary math proficiency
Zero+ meets standard.
69% less $meal
76% less $meal
81% less $meal
• 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.
