Dozens of Asian-American activists on Monday blasted Mayor Bill de Blasio’s plan to eliminate the admission test to the city’s top high schools in a bid to increase diversity among students there.

“The mayor is pitting minority against minority and that’s really messed up,” fumed Kenneth Chiu, president of the New York City Asian-American Democratic Club.

The Coalition of Asian-Americans for Civil Rights gathered about 70 people at the Golden Imperial Palace catering hall in Brooklyn to denounce de Blasio’s proposal, which coalition president John Chan called “the last straw for us.”

“This policy causes chaos in the Asian-American community and we’re here to reject this policy,” Chan said.

“New York City has taken our money for several years and no one has provided help for us. They are taking advantage of us and we must stand together to object toward a better policy.”

Asian-Americans account for a disproportionate number of students at the city’s eight selective high schools, comprising between 61 and 74 percent at top-rated Stuyvesant, Brooklyn Tech and the Bronx High School of Science.

Chan said his group would rally against de Blasio outside City Hall on Tuesday afternoon.

Another protest is being planned for Sunday, he said, either outside City Hall or the mayor’s official Gracie Mansion residence.
