Sean F. Reardon, Ximena A. Portilla (August 2016 ). Recent Trends in Income, Racial, and Ethnic School Readiness Gaps at Kindergarten Entry, American Educational Research Association (AERA) Open, DOI: 10.1177/2332858416657343,
This study found that low-income kindergarten students have reversed the trend of growing academic achievement gaps between them and their higher-income peers. Academic achievement gaps grew from the 1970s to the 1990s, but from 1998 to 2010 the gaps shrank 10-16%. During this time frame, the White-Hispanic kindergarten readiness gap and the White-Black gap each dropped. Researchers attributed the improved preparedness, in part, to low-income parents spending significantly more time reading to their children, taking them to museums, and introducing them to educational games on computers. Despite the narrowing of these readiness gaps, they remain large and, in fact, progress is so slow that at the rate that improvements are occurring, it will take at least 60 years for disparities to be eliminated.
