Summary:
ZIP code 85396 has four listed elementary schools, with enrollments ranging from 262 to 648 students. Three serve through fifth grade, while Tartesso and Festival Foothills extend through eighth grade. The latest all-grades results show a mixed picture: the four-school averages are 35% in ELA and 30% in math, compared with state rates of 41% and 33%. The clearest overall standout is The Odyssey Preparatory Academy - Sienna Hills, the only school above the state in both subjects.
Odyssey leads all-grades ELA at 43% and math at 40%, respectively 11 and 19 percentage points above the lowest results at Festival Foothills Elementary School (32% ELA, 21% math). Desert Sunset Elementary School and Tartesso Elementary School each post 33% ELA; their math results are 28% and 31%. Odyssey also leads fifth-grade science at 52%, compared with 24% at Desert Sunset and 22% at Tartesso; the three-school average is 33%, close to the state’s 34%. Grade-specific results add important exceptions: Festival Foothills’ third-grade math is 41%, above the state’s 38%, while Desert Sunset’s fourth-grade math matches its state rate at 40%.
SchoolDigger’s ranking history is mixed rather than a sign of a shared upward trend: from 2023–24 to 2025–26, Desert Sunset stayed at the 28th percentile, Odyssey moved from the 56th to the 51st, and Tartesso from the 42nd to the 33rd; their average fell about 5 percentile points. Festival Foothills’ available history rises from the 60th percentile in 2021–22 to the 64th in 2023–24. These are SchoolDigger relative rankings, not test-score trends. Within schools, Tartesso’s math ranges from 24% in fourth grade to 35% in third and fifth, and Odyssey’s strongest reported grade-level results are in fifth grade. Odyssey has the lowest student–teacher ratio, 16.2, while Festival Foothills’ is 22.2. Free/reduced-lunch rates are not supplied, and the schools’ different grade spans mean all-grades comparisons are not perfectly alike.
