What Parents Should Know
At 153 students, Calla 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.
Test scores at Calla High 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.
73% of students at Calla High 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.
