What Parents Should Know

At 32 students, Mayfield Colony Elementary - 04 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.

Test scores at Mayfield Colony Elementary - 04 sit below average, but its growth scores are strong: students here make above-average progress year over year. The raw numbers haven't caught up, but a school that keeps moving kids forward is doing the harder, more important work.

Mayfield Colony Elementary - 04 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.
