Summary:
Zip code 61530 includes three schools in Davenport Elementary School (pre-K–grade 4), Eureka Middle School (grades 5–8) and Eureka High School (grades 9–12), all in Eureka CUD 140. The overall picture is strong: the elementary and middle schools’ 2025–2026 all-grades results are above state in both ELA and math, and the high school is above state on its reported ACT and PreACT results. The most important finding is that every reported test result at all three schools exceeds its corresponding state figure.
Eureka Middle stands out in ELA and science: its all-grades ELA result is 78%, versus 69% at Davenport, and its fifth-grade science result is 78%, 30 points above state. Davenport is nearly even with the middle school in all-grades math, at 59% compared with 58%. At the high school, ninth-grade PreACT is especially strong in math and science, with state advantages of 28 and 27 points. The relatively smaller high-school margins are on the eleventh-grade ACT: even its smallest, in science, is still 5 points above state.
