Summary:
Zip code 62951 has three schools in Johnston City CUSD 1, serving students from prekindergarten through grade 12: Jefferson Elementary School (PK–2), Washington Middle School (grades 5–8), and Johnston City High School (grades 9–12). Together they enroll 894 students, with school enrollments ranging from 270 to 328. The clearest recent academic strength is at Washington, where 2025–26 all-grades IAR results reached or matched state results after a sharp rise from the prior year.
Washington stands out in its latest IAR results: its all-grades ELA proficiency was 58%, about 1 point above the state’s 56%, while math was 40%, matching the state. Its strongest grade-level results include sixth-grade ELA (69% versus 59% statewide) and seventh-grade math (49% versus 40%). The high school’s 2025–26 ACT results are mixed: 11th-grade ELA was 53% versus 50% statewide, but math was 33% versus 40% and science was 34% versus 48%. Jefferson cannot be placed above or below the others academically because no test scores are supplied for it.
Washington’s all-grades IAR scores rose 20 points in ELA and 23 points in math from 2024–25 to 2025–26. At the high school, ACT ELA and math improved by 7 and 11 points, respectively, while science fell by 3 points. SchoolDigger’s 2025–26 rankings place Washington at the 46th percentile and the high school at the 40th; Jefferson’s most recent listed ranking is older, from 2013–14, at the 30th percentile. For context, 2024–25 free/reduced lunch eligible shares were 64% at Jefferson, 62% at Washington, and 50% at the high school; student-teacher ratios were 14.5, 12.4, and 11.7, respectively. These measures describe the schools but do not explain their results; tests, grades served, and years differ, so they do not support a direct overall school ranking.
