Summary:
The Odyssey Preparatory Academy Inc. includes four Arizona schools: three elementary schools and one school serving grades 6–12. In the 2025–26 all-grades results, the schools average 42% in ELA, close to the 41% state result, and 38% in math, above the 33% state result. Those averages conceal large differences between schools, especially in math. The clearest standout is The Odyssey Preparatory Academy Goodyear, which leads the other elementary schools in all six grade 3–5 ELA and math comparisons.
Goodyear has the strongest all-grades results, with 54% proficient in ELA and 60% in math—13 and 27 percentage points above the state, respectively. In matched grades 3–5, it averages 57%, compared with 36% at Buckeye and 41% at Sienna Hills. Buckeye has the lowest all-grades ELA result at 35%, while Odyssey Institute for Advanced and International Studies has the lowest math result at 15%, 18 points below the state; Buckeye’s math is 36%, 3 points above it. Sienna Hills’ profile varies by grade: its grade 5 math is 15 points above the state, but its grade 4 math is 13 points below.
SchoolDigger’s average statewide percentile for the four schools fell from 60 in 2023–24 to 55 in 2025–26, a 5-point decline, though Goodyear rose from the 76th to the 77th percentile. In 2025–26, SchoolDigger rated Goodyear at the 77th percentile with 4 stars, compared with Buckeye at the 41st percentile and 2 stars, Sienna Hills at the 51st percentile and 3 stars, and the Institute at the 52nd percentile and 3 stars. Goodyear’s elementary-school student–teacher ratio is 16.8, versus 16.0 at Buckeye and 16.2 at Sienna Hills, so its strong results do not coincide with the lowest ratio. Grade 5 science results also differ: Sienna Hills is 18 points above the state, Goodyear 4 points above, and Buckeye 13 points below. Free/reduced-lunch figures were unavailable, and the test results do not provide a comparable multi-year trend.
