School ratings, enrollment, grade levels, programs, boundaries and assignments can change. Proximity to a school does not guarantee attendance. Buyers should verify the current assignment for a specific property directly with Mountain View School District and Chaffey Joint Union High School District, and review information from the school, district and California Department of Education.
