New standardized test results prove that California is struggling when it comes to race, education and closing the achievement gap. The racial divide between the lowest and highest scorers is remarkable; black students had the lowest scores of any group. About a third met grade-level standards in English and fewer than 20 percent were proficient in math. Compare that to the highest-scoring group, Asian-Americans: roughly 70 percent met or exceeded the standards. The tests are based on the Common Core learning standards, and they’re supposed to measure whether students are on track to be college-ready, so the implications could be far-reaching.
