What Parents Should Know

At 136 students, Southwest Preparatory School-northwest 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 Southwest Preparatory School-northwest 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.

Southwest Preparatory School-northwest is a charter school: publicly funded, but run with more independence than a traditional district school. Many charters are built around a specific model or focus, so it's worth understanding this one's mission, how enrollment works, and how it differs from the district schools nearby.
