What Parents Should Know
At 186 students, Centennial School is on the smaller side. That usually buys more individual attention and teachers who know every kid by name, with the trade-off of fewer electives and extracurriculars than a larger school can staff. Ask what activities it actually offers.
Centennial School sits in a rural area, which can mean longer drives for some families. Rural schools are often community anchors with smaller classes, but check transportation, after-school options, and access to specialized services before you commit.
46% of students at Centennial School were chronically absent in the 2022-23 school year, above the national average. Chronic absenteeism means missing 15 or more school days, and at high rates it drags on classroom pacing for everyone. Ask what the school does to help families get kids to class consistently.
