C.A.S.T.L.E has lower chronic absenteeism, 77.4% versus 98.7% at Invictus, and a better student-teacher ratio, 14.1 versus 22.2, though its chronic absenteeism rate is still very high and its graduation rate is much lower. Free/reduced lunch data is blank for both schools, so economic disadvantage cannot be compared here.
In 2024–2025 Ohio State Tests, Invictus was ahead in four of six subjects: Biology 22.2% vs. 10.0%, English II 14.0% vs. 11.4%, Geometry 20.0% vs. 19.5%, and Algebra I 33.3% vs. 24.4%. C.A.S.T.L.E was ahead in American Government, 26.2% vs. 23.1%, and American History, 29.4% vs. 28.6%. Every subject score for both schools is below the state average. Invictus’s highest score, Algebra I at 33.3%, is still below the state’s 59.4%. Simple averages across the six subjects are about 23.5% for Invictus and 20.2% for C.A.S.T.L.E, compared with about 62.0% statewide. Overall, Invictus is relatively stronger on graduation, enrollment, rank, and most tests; C.A.S.T.L.E is relatively stronger on absenteeism and class size. Neither school is strong on state accountability measures, and attendance and proficiency remain serious concerns at both.
