If I understand this correctly, they're not saying asian students have to score almost twice as highly than black students. Instead, they're saying, "Okay, a majority of asians are passing our standards and proportionally fewer of black students are, so let's set those as a baseline and seek to improve from there."

I find it questionable they would set the bar for what portion of students should pass state standards based on race, but if black students statistically struggle compared to asian students, I can see why they would do this.
