ZIP code 46818 is home to a single middle school, Carroll Middle School, which serves grades 6 through 8 with 1,004 students as part of Northwest Allen County Schools.

The school has improved steadily, moving from 187th of 491 (62nd percentile, 3 stars) in 2023–2024 to 126th of 480 in 2024–2025, then to 115th in 2025–2026.

Science is the standout, at 59.63% for both all grades and 6th grade — 18.43 points above the state's 41.2% and ahead of the district's 57.37%. Sixth-grade ELA is also strong at 55.05%, well above the state's 41.3%.
Math is the clearest gap: all-grades Math is 39.64% versus the district's 50.03%, a 10.39-point difference, and 7th-grade Math (36.47%) trails the district by 8.58 points. Performance also declines in upper grades — ELA falls from 55.05% in 6th grade to 45.4% in 8th, and Math from 46.48% to 36.09%. Still, the school beats the state at every grade level reported.
