School Overview

Mariposa Elementary sits in Ontario's inland communities, where families are navigating a competitive Southern California landscape on a more affordable stretch of the IE. The school serves a neighborhood where many parents are working hard to give their kids a strong foundation, and while test scores land in the lower quarter statewide, science stands out as a relative bright spot worth noting. Families who are hands-on and engaged with their child's learning — and who want to stay connected with teachers — tend to get the most out of schools like this one in the Ontario-Montclair district.
