What Parents Should Know
At 5 students, Casterlin High 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.
At 1.7:1 students to teachers, Casterlin High sits well below the national average. Smaller classes like that usually mean more one-on-one time between students and teachers.
Casterlin High 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.
