Original Research by School Decision on Dos Rios Elementary
Dos Rios Elementary sits within Tolleson, a small, industrial city in the Phoenix West Valley where distribution centers and food processing plants dominate the daytime landscape. Tolleson is a compact place, oriented around major freight corridors, and its employment base far outpaces its residential population. The school is part of the Union Elementary District, which serves a portion of the area.
This is a regular public school covering kindergarten through eighth grade, which means it offers a single-building pathway from early elementary through middle school. Families who need a high school will need to look to one of the other districts that serve Tolleson after eighth grade. The enrollment is substantial for a K-8 school, and the student body is predominantly Hispanic, with a meaningful share of Black students and smaller numbers of White, American Indian or Alaska Native, and Asian students.
State testing data for the most recent year presents a picture that requires some unpacking. In mathematics, results for grades three through eight were suppressed, so there is no publicly reported proficiency rate for that subject. In English language arts, scores were available for grades six through eight, and they showed that a modest share of students met the proficiency standard. In science, tested in grades five and eight, the share of students scoring proficient or above was also modest. Across all subjects and grades where data could be reported, the school's overall proficiency index placed it in the bottom quarter among elementary and middle schools in Maricopa County. A parent with a child entering these grades would want to ask the school directly about current math performance and any support programs in place.
There is no graduation rate because the school does not serve high school grades. The data did not include information on chronic absenteeism, disciplinary incidents, or the share of students who are English learners or receive special education services. Those are meaningful gaps for a family trying to assess the school's climate and the level of targeted academic support.
Housing in the Tolleson area is moderately priced relative to the national market, with typical home values and rents running slightly below the Arizona state median. The local economy, anchored by logistics and food processing, has kept unemployment low. The city has seen modest population growth over recent decades, with new industrial expansions outpacing residential development.
The district brief turned up no major recent changes that meet the threshold for lasting impact. At the school level, there is no information about before- or after-school programming, arts offerings, or special academic tracks. For families weighing Dos Rios Elementary, the lack of visible test results in math and the below-average proficiency rates in the subjects that are reported are the central facts. A parent considering this school should connect directly with the principal to understand what academic interventions and enrichment the school provides, particularly in the upper elementary and middle grades.
