Vielä tuosta score gapista. Mielenkiintoinen aihe.

Why does the gap exist?
Stanford's Educational Opportunity Monitoring Project has dug deeply into available data, searching for what other factors beyond poverty might be influencing the black-white achievement gap.
Researcher Sean Reardon studied the multiple factors that contribute to the gap, using more than 200 million test scores from schools and districts across the country.
Reardon and his fellow researchers wanted to see which factors are most closely correlated with the achievement gap.
They looked at two sets of factors that account for about three-fourths of the gap.
The first set has to do with a student's
family resources, residential segregation and neighborhood factors.
The second set has to do with e
ducation policies and practices, including school segregation, disparities between schools and also within schools.
The figure below, from Reardon's research, depicts how they believe those factors interact.

Though Reardon's research, the first to look at gaps nationwide, was not able to identify causal relationships, as in what actually
causes the achievement gap. Instead, they found correlations, as in here are some factors that exist when we find achievement gaps.
They found clear links to parental income, but also parental education levels and school segregation.
Reardon told AL.com, "Achievement gaps are shaped by many factors, as we describe in the paper. Socioeconomic differences between white and black children play a role - since higher income students come from homes with more economic resources, live in better neighborhoods, and often have access to higher quality child care and preschool experiences."
"But," Reardon said, "segregation also plays a large role - in highly segregated school systems, where black children attend higher poverty schools than white children - achievement gaps are larger."
That concentration of poverty exacerbates the gap, Reardon said, "because high-poverty schools often have few resources, have a harder time attracting and retaining the most skilled teachers, and have a higher proportion of high-need children. All of these mean that children in high-poverty schools often have less access to rigorous and challenging curriculum."
