Summary:
Zip code 60534 includes three schools in Lyons School District 103: two elementary schools serving grades PK–5 or K–5 and one middle school serving grades 6–8. The latest results show the two elementary schools are relatively close to state results overall, while Washington Middle School is below its state benchmarks in every reported grade and subject, making Washington’s broad shortfalls—especially in math—the clearest concern in this area.
Costello School leads the elementary schools in all-grades ELA: 54% proficient, compared with 51% at J W Robinson Junior Elementary School, a 3-point difference; both are below the 56% state result. Robinson leads in math, with 35% proficient versus Costello’s 31%, though both are below the state’s 40%. The lead varies by grade too: Costello is ahead in grade 3 ELA by 9 points, while Robinson leads in grade 4 ELA by 13 points. Washington’s all-grades results are 43% in ELA and 18% in math, respectively 13 and 21 points below the state.
Results improved from 2024–2025 to 2025–2026 in most school-subject comparisons: 7 of 9 gaps to the state narrowed. Costello and Robinson both improved in ELA and math, and Washington improved in ELA and science; the exceptions were Washington math, where its gap widened by 1 point, and Robinson science, where its result fell farther behind the state. SchoolDigger’s latest rankings are 44th percentile for Costello, 41st for Robinson, and 13th for Washington; Washington’s ranking fell 18 percentile points over the three listed years, despite recent ELA and science gains. For context, the 2024–2025 free/reduced lunch eligible figures were 74% at Costello, 87% at Robinson, and 80% at Washington; student-teacher ratios were 8.5, 8.9, and 11.1, respectively. Chronic absenteeism in 2025–2026 was 30% at Costello, 19% at Robinson, and 37% at Washington, compared with 24% statewide. Some elementary grade-level results were suppressed, so those particular results cannot be compared.
