Summary:
Tolleson, Arizona, has 12 schools in this set—nine elementary schools and three high schools—serving students from elementary through high-school grades across several local districts. Elementary results are generally below state figures, while the high-school picture is sharply divided: the two conventional high schools average 16% in 11th-grade ELA and 14% in math, versus state results of 38% and 31%. The most important takeaway is that University High School is a major exception, with much higher proficiency than the area’s other high schools.
University High School leads the high schools with 91% ELA and 89% math, compared with 14% and 16% at Tolleson Union High School and 18% and 12% at Sierra Linda High School. University is also strong in 11th-grade science, at 71% versus the state’s 19%. Among elementary schools, Arizona Desert Elementary School leads with 35% ELA and 25% math, though those results remain below the state’s 41% and 33%. At the lower end, Union Elementary School has the lowest elementary ELA result at 10%; it and Dos Rios Elementary tie for lowest math at 7%. Graduation offers another perspective: Tolleson Union’s rate is 91%, compared with 80% statewide.
SchoolDigger rankings show mixed movement rather than a clear area-wide shift: from 2023–24 to 2025–26, Hurley Ranch Elementary rose 11 percentile points, while Tres Rios Elementary fell 17; University ranks fourth of 256 Arizona schools, at the 98th percentile, with five stars. School size and student–teacher ratio do not neatly sort results: University has a 23.1:1 ratio and the highest high-school scores, while Union has a 14.9:1 ratio and the lowest elementary ELA result. These proficiency figures cover one year, and ratios are unavailable for three elementary schools.
