In the light of the discussions of charter schools in the poss below, and given that I attended a graduate seminar of education policy students last night at which none of the students had read it, it seems worth re-drawing your attention to Greg Duncan and Richard Murnane’s edited volume Whither Opportunity?: Rising Inequality, Schools, and Children’s Life Chances. Its already 5 years old, but it is really a brilliant achievement, drawing together numerous experts (if we’re allowed to listen to experts any more) with the task of summarizing everything we know about the relationship between economic inequality and educational disadvantage in the US. The take home is fairly simple: there’s a very strong relationship between economic inequality and educational disadvantage and after reading the whole book you might still believe (as I do) that it is possible to improve educational outcomes for poor children through improved schooling but you cannot believe that we could get large changes in outcomes without corresponding changes to the environments poor children grow up in — which would require massive reductions in both inequality and poverty.

I think its fair to say that the headline study was Sean Reardon’s finding that the achievement gap (measured by standardized tests) between rich and poor students has increased during the same 50 years during which the black-white achievement gap has decreased, as shown in the following graph:

Other findings include Meredith Phillips’ finding that between birth and age six, wealthier children will have spent as many as 1,300 more hours than poor children on child enrichment activities such as music lessons, travel, and summer camp, and the contribution by Waldfogel and Magnusson showing that the gap in ‘enrichment spending’ between rich and poor has expanded massively in the past 40 years — and that affluent families spend more than $8000 a year per child on enrichment activities. A child from a poor family is two to four times as likely as a child from an affluent family to have classmates with low skills and behavior problems – attributes which have a negative effect on the learning of their fellow students, and the rich=poor achievement gap in k-12 is accompanied by a growing income-based gap in college completion.

One of the studies shows that local job losses can lower the test scores of students with low socioeconomic status, whether or not the students’ parents have suffered the job losses; another that and students learn less math if they attend schools with high student turnover during the school year (one count against school choice, but also against allowing landlords to evict tenants with children mid-year).

Of course, to most readers none of these finding will be shocking (though, the Reardon finding is quite noteworthy). But they are worth bearing in mind. I am startled by local school officials for example, who say that citing poverty as a reason for low achievement is an ‘excuse’, and also by academics in education I come across who are reluctant to admit that poverty has seriously detrimental effects on the poor and the ability of poor children to learn (if poverty doesn’t have bad effects on those who are subject to it, elminating it might still be nice but doesn’t seem morally as urgent as it, in fact, is). As I say, I’m only mentioning Whither Opportunity again now after meeting a whole group of grad students who are concerned with educational inequality and didn’t know of it, and being prompted by the discussions of charter schools. Also I’d recommend going to Leo Casey’s comment on one of the threads which gathers together some other useful links.
