School Overview

Del Sur Senior Elementary sits in the high desert community of Lancaster, where the Antelope Valley's wide-open spaces and strong military and working-class roots shape a tight-knit neighborhood feel. The school serves a broad K-8 range, which can be appealing for families who want their kids to stay in one place through middle school, though academics here tend to run below the state median — particularly in math. Families who are weighing options in the Westside Union district may want to visit in person to get a sense of the school's culture and extracurriculars, since community connection often matters just as much as test scores in a place like Lancaster.
