To qualify for the award, the schools' socio-economically disadvantaged students must have doubled the achievement targets set for them for two consecutive years.
Hamilton and Willard were honored because all of its students made progress toward California's proficiency standards.
This is the sixth consecutive year that Willard Elementary School has won the award.
Hamilton Elementary was also named a National Blue Ribbon School last year.
