Schools
Westside Costa Mesa is large and its elementary and middle assignments vary strongly by street (19th Street is a rough middle-school divide).
Elementary (K-6)
Rea, Pomona, Wilson, Victoria, or Whittier Elementary (by pocket) · Newport-Mesa USD
Middle
TeWinkle Middle (north of 19th) or Ensign Intermediate (south) · Newport-Mesa USD
High (9-12)
Estancia High School (GreatSchools 6/10) · Newport-Mesa USD
School attendance areas are assigned by address and change over time; larger villages span several schools, so confirm the current elementary, middle, and high assignment for a specific address with the district.
