Summary
A. H. Morgan Elementary is a K–5 school serving 487 students in Rialto, California, and is part of Rialto Unified. Its results vary considerably by grade: fifth graders stand out, while some earlier-grade results are weaker. The clearest takeaway is that, despite relatively strong nearby rankings in English and math, the school’s all-grade proficiency remains below California’s in English, math, and science.
Compared with nearby schools, Morgan is strongest in English language arts (ELA) and math, and weakest in science. In 2025–2026, 38% of students were proficient in ELA, the second-highest result among 11 nearby schools, though below the district’s 44% and California’s 49%. Math proficiency was 27%, third-highest nearby and 2 percentage points above the district, but 11 points below the state. Science proficiency was 21%—eighth-highest nearby, 7 points below the district, and 15 below the state. Fifth grade is a notable bright spot: 53% were proficient in ELA, above the state’s 49% and district’s 41%, and the highest result among nearby schools, ahead of W.J.C. Trapp Elementary. Fifth-grade math was 32%, higher than any nearby school and above the district’s 21%, but 5 points below the state. In contrast, third-grade math proficiency was 27%, compared with 38% in the district and 47% statewide.
From 2022–2023 to 2025–2026, ELA rose by 1 percentage point, math fell by 1 point, and science rose by 3 points; meanwhile, the gaps with the state widened in all three subjects. SchoolDigger ranked Morgan 3rd among these nearby schools in 2025–2026, at the 33rd percentile with 2 stars; its percentile had fallen from 40 in 2023–2024. The 2024–2025 student–teacher ratio was 23.5, the third-highest nearby, and 86% of students were free/reduced lunch eligible that year. SchoolDigger’s 2024–2025 ranking for Homeless Students was 35 of 429, at the 92nd percentile with 5 stars, compared with the school’s overall 39th percentile that year. For African American Students, it ranked 126 of 569, at the 78th percentile with 4 stars. These group rankings indicate notably higher relative standing than the school’s overall ranking, but do not explain why results differ.
