Original Research by School Decision on Sator Sanchez Elem School
Sator Sanchez Elementary is a kindergarten-through-fifth-grade school in Joliet serving a school population that is overwhelmingly Hispanic, with a smaller share of Black students and very few white or Asian students. The school enrolls a small student body for an elementary school, spread across seven grades from pre-K through grade five.
State test results show proficiency rates that are markedly low across both English language arts and math in grades three through five, the grades where Illinois administers the IAR assessment. In third-grade math and ELA, about one in eight students scored at proficient or above. Fourth-grade math proficiency sits around one in ten. Fifth-grade results are lower still: in math, about one in sixteen students reached proficiency; in ELA, the rate is closer to one in three or four. Science proficiency in fifth grade, measured on a different assessment, is also low at about one in eight. The participation rate in testing is very high, well above state minimums, so these results reflect the performance of nearly all tested students rather than a subset. No state testing data appears for grade six and above because this is an elementary school and the state does not test those grades at the elementary level; the test data available is limited to the grades the school serves and that the state assesses.
When compared against other districts in Will County, Sator Sanchez's overall proficiency index places it in the bottom quartile. The school's peers in the county show substantially higher proficiency rates, underscoring that this school's test performance is well below the local norm.
The school sits in Joliet, a large suburban city anchored by downtown civic and cultural sites—the Rialto Square Theatre, Will County Courthouse, and Harrah's Casino—and a significant industrial and logistics base. The city has experienced modest population growth recently and is seeing development concentrated on its west side, with new subdivisions and major employers like Amazon, IKEA, and ExxonMobil establishing operations. Downtown revitalization efforts include a streetscape project and a new city square plaza. The local housing market shows a median home value in the mid-range for the state, with modest recent price appreciation and a balanced inventory of active listings.
The parent district, Joliet PSD 86, recently secured voter approval for a major bond referendum to address aging facilities and overcrowding district-wide. Two new junior high schools are set to open for the 2026-2027 school year, and expansions at other elementary schools, including Thomas Jefferson, are underway or completed. This capital investment reflects a district responding to facility and enrollment pressures that families moving into or considering Joliet will notice.
Sator Sanchez has no reported information on free-or-reduced-price-lunch eligibility, English learner enrollment, or special-education enrollment, so a reader looking to understand the full scope of student need and support would want to seek that information directly from the school. Similarly, data on attendance, discipline, staff, and course or program offerings were not available. A parent or resident considering this school may want to learn more from the school itself about intervention programs, reading and math supports, the student services offered, and whether there are specialized pathways or partnerships in place to address the proficiency gaps the test data shows.
