Summary
Happy Valley School East Campus is a K–6 school in San Tan Valley, Arizona, serving 396 students. Its 2025–2026 proficiency was 41% in English language arts (ELA) and 25% in math, while fifth-grade science proficiency was 28% in 2024–2025. The central concern is math: proficiency was below the state in grades 3, 4, 5, and 6, with results of 24%, 26%, 32%, and 21%, respectively.
ELA is the school’s strongest subject against state and district results: its 41% proficiency matched both, although nearby K–6 schools averaged 48%. Math proficiency was 25%, eight percentage points below the state, equal to the district, and 15 points below the nearby-school average of 40%. Science was 28%, six points below the state and equal to the district; nearby schools averaged 40%. So, while ELA meets state and district levels, the school’s results are below nearby averages in all three subjects. Within ELA, third-, fifth-, and sixth-grade results were three points above the state, but fourth grade was seven points below it.
Science proficiency declined from 36% in 2022–2023 to 28% in 2024–2025, while the state stayed at 34%. SchoolDigger placed the school at the 40th percentile with 2 stars in 2025–2026, below the nearby-school average ranking of the 56th percentile; its own ranking fell 29 points from the 69th percentile in 2020–2021. The 2024–2025 student–teacher ratio was 18, compared with 18.8 at nearby schools, and the only reported free/reduced-lunch rate was 50% in 2022–2023. SchoolDigger’s subgroup measure showed a notably stronger standing for Low Socio Economic Status Students: the 60th percentile in 2024–2025, compared with the school’s overall 39th. Its measure for White Students was much lower: the 6th percentile in 2025–2026, compared with the school’s overall 40th.
