Summary

Centennial Elementary School is a public elementary school in Polo CUSD 222 district, serving 297 students in grades PK-5. This high-performing school consistently outperforms state and local averages in academic achievement, particularly in supporting its low-socioeconomic status (SES) student population.

Centennial Elementary School's academic performance is impressive, with 67.5% of students proficient or better in English Language Arts and 71.1% in Mathematics, compared to the state averages of 53.1% and 38.5%, respectively. The school's focus on supporting its low-SES students has been particularly successful, ranking 62nd out of 1,800 Illinois elementary schools in this subgroup. Additionally, the school's higher spending per student ($13,613 in 2023-2024) and low student-teacher ratio (ranging from 13.7 to 15.4) may contribute to its strong academic performance.

Centennial Elementary School's consistent growth and high performance are noteworthy, as it has moved from 1,073rd out of 2,046 Illinois elementary schools in 2015-2016 to 297th out of 2,056 in 2024-2025, with a consistent 4-star rating from SchoolDigger.
