1) These statistics may differ from those in state and federal accountability results. They were calculated based on where students tested regardless of school entry date. Home school students and students with invalidated scores were excluded from the calculations.
2) If the number tested is less than 10, no other statistics appear.
Using the ACT Readiness Benchmarks, performance is classified into four ACT
Readiness Levels based on student scale scores:
In Need of Support - below the low cut
Close - at or above the low cut and below the benchmark
Ready - at or above the benchmark and below the high cut
Exceeding - at or above the high cut
where, except for writing, the low and high cuts are the lower and upper limits of a 95% confidence interval around the Readiness Benchmark. Writing cuts are based on expert judgement.

Ready - at or above the benchmark
Column Legends:
A) Total number of students tested
D) Mean (scale score) for the group of students
B) Percentage of students scoring Not Ready
