What other rankings don't show you

That's 2.6 points below the Antelope Valley Union High district average of 9.3%. The 1 nearby schools within ~3 miles average 33.2% exceeded — 26.5 points higher. The gap between "met" and "exceeded" can reveal how much a school's curriculum challenges students beyond proficiency.
