Summary:
ZIP code 55014 has exactly one middle school, Centennial Middle, which serves grades 6–8 in Lino Lakes, Minnesota, as part of the Centennial Public School District. It is a large school with 1,595 students, a free/reduced lunch rate of 25.39%, and a student-teacher ratio of 26.7. The district is ranked 58th of 458 in Minnesota, in the 87th percentile with 4 stars. Because this is the only middle school in the ZIP code, parents do not have a local middle-school alternative to compare within 55014.
Academically, the school is generally above the state in math and reading. In 2025–2026, reading proficiency was 52.5% versus the state’s 48.6%, and math was 46.8% versus 44.9%. At the grade level, it was above the state in every math and reading grade. Its strongest advantage was 8th-grade math, at 52.1% compared with the state’s 42.3%, a 9.8-point gap. Science is the clear weak spot: 8th-grade science was 15.6%, slightly below the state’s 8th-grade science figure of 16.7%. The state all-grades science figure is 25.5%, but that comparison is not fully apples-to-apples because the school’s science measure is effectively 8th grade only.
Recent trends are mixed. The school’s rank slipped from 49th of 545 (91st percentile, 5 stars) in 2023–2024 to 125th of 546 (77th percentile, 4 stars) in 2025–2026. From 2024–2025 to 2025–2026, proficiency fell in math (–7.17 points), reading (–7.74 points), and science (–6.07 points), while statewide declines were much smaller. Even so, the district remains highly ranked, and the school is still above the state in math and reading. The key question for parents is whether the recent drop is a one-year dip or the start of a longer downward trend, with science remaining the clearest area to watch.
