NYT: Middle class 6th graders two years behind upper middle class 6th graders

If your Asian community has lots of people of Chinese or Indian origin, be aware that immigration patterns have selected immigrants from China and India to have high educational attainment. For example, about 50% of immigrants from China and about 70% of immigrants from India have bachelor’s or higher degrees (compare to about 6% in China and around a quarter in India and the US overall). So, before you make any conclusions based on the more visible characteristics of race and ethnicity, take note of the selection effect by immigration with respect to ethnic groups where many are immigrants or only a generation removed from immigration.
