Summary:
ZIP code 60040 has one listed school, Oak Terrace Elementary School, serving prekindergarten through grade 5 with 494 students in North Shore School District 112. In 2025–2026, Oak Terrace’s all-grade proficiency was 59% in English language arts (ELA) and 41% in math, 2 and 1 percentage points above state rates; fifth-grade science proficiency was 40%, 8 points below the state. Its rates were also below district results by 20 points in ELA and 24 points in math. The key concern is that Oak Terrace has lost ground against the state in all three subjects with two years of comparable results.
There is no other listed school to rank above or below Oak Terrace, so its grade-level results offer the clearest picture of where it stands out. ELA was strongest in grade 4, at 67% compared with 56% statewide, and grade 3 was also above the state, 63% versus 48%; grade 5 ELA was lower, at 49% versus 55%. Math showed a different pattern: grade 5 was above the state, 44% versus 36%, while grades 3 and 4 were below it. Fifth-grade science was also below the state. These contrasts mean the all-grade results do not tell the whole story for a family considering a particular grade.
Oak Terrace’s scores declined from 2024–2025 to 2025–2026: all-grade ELA fell 2 percentage points and math fell 11, while state rates rose 3 and 1 points, respectively. Fifth-grade science fell 9 points as the state rate rose 7, shifting Oak Terrace from 8 points above the state to 8 points below. SchoolDigger ranks Oak Terrace 942nd of 1,737 schools, in the 46th percentile, with 2 stars; its history moved from the 64th percentile in 2023–2024 to the 70th in 2024–2025, then to the 46th in 2025–2026. Other context: its student–teacher ratio was 12.1 in 2024–2025, and 46% of students were free/reduced lunch eligible that year. Because the ZIP-code list contains just one school, it cannot show how Oak Terrace compares with other local schools.
