Who each school fits
Cortada Elementary
Cortada Elementary suits families who prioritize growth momentum over absolute proficiency levels — its 9.6/10 growth score is the stronger of the two schools, meaning students are making fast gains from wherever they start. It is also the larger campus, which can mean more peer diversity and a broader social environment, and may better reflect the economic realities of the surrounding El Monte community at 95% free/reduced-price lunch eligibility.
Rio Vista Elementary
Rio Vista Elementary is the better fit for families where current academic achievement level is the primary concern — its 8.9/10 academic score and #95 California state rank put it in an elite tier, and a 15.0:1 student-teacher ratio means more adult attention per child than Cortada can provide. Parents seeking a smaller, high-achieving campus where proficiency benchmarks are measurably stronger will find Rio Vista the clear choice.
