What Parents Should Know
At 154 students, Coast Union 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.
Coast Union 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.
