In ELA, the schools are nearly even: Middle has 64% proficient and Elementary 63%, with both above the 56% state rate. Erie High School has a more mixed grade-by-grade picture: grade 9 is above state rates in all three PreACT subjects, while grade 10 ELA is below the state rate and math is only just above it. Grade 11 ACT results are above state rates in all three subjects.
Recent trends are mixed rather than uniformly upward.
