7 The phrase "American Dream" was first coined by the historian James Truslow Adams, who said, in part, that it was "that dream of a land in which life should be better and richer and fuller for everyone, with opportunity for each according to ability or achievement."

12 Throughout this narrative, the terms "human capital" and "skills" will be used interchangeably. While the term "skills" is often associated solely with cognitive abilities, it is used in its broadest sense here. So "skills" and "human capital" are defined as the knowledge, competencies, and attributes needed for work and personal life. These include reading, writing, and mathematics skills; general and specific knowledge; analytical, problem solving, and technical skills; the ability to learn independently and continuously upgrade skills; interpersonal skills such as collaboration, communication, and teamwork; and character traits such as motivation, persistence, conscientiousness, reliability, self-discipline, and curiosity, often referred to as noncognitive skills.

As we explain in the subsection entitled "America's Skills Gap," although datasets commonly use educational attainment as a proxy for skills, it is important to distinguish between them.  The two are clearly related, but data show that some students with educational credentials do not have the skills we might expect from their level of schooling.

17 While this narrative focuses on opportunity in the United States, another positive outcome is that there has also been a dramatic reduction in global poverty as documented by The World Bank (http://www.worldbank.org/progress/reducing_poverty.html) and the United Nations (http://www.un.org/millenniumgoals/poverty.shtml).

31 In fact, the figure of 60 percent is an underestimate of the proportion of adults at the lowest levels as no data was collected for just over 10 percent of adults who either did not demonstrate the minimal computer skills required to complete the assessment (including the ability to use a mouse to move, point and click, and type on a keyboard) or refused to participate in the computer-based portion of the survey.

In addition, appropriate support must be available for those individuals who have not been able to develop requisite skills.  Such support can be provided through social networks in the community or, in some cases, through technological solutions.  One example of the latter is tax preparation software that greatly reduced the cognitive skills required to file taxes.

Because NAEP is a low-stakes assessment, there are long-standing questions about the level of engagement and effort of the 12th graders who participate in the assessment and, consequently, about the validity of the reported results. A randomized control study of the impact of monetary incentives on performance found that NAEP may both underestimate the reading abilities of students enrolled in 12th grade and yield biased estimates of certain achievement gaps. See Henry Braun, Irwin Kirsch, and Kentaro Yamamoto, "An Experimental Study of the Effects of Monetary Incentives on Performance on the 12th-Grade NAEP Reading Assessment," Teachers College Record 13, no. 111 (2011), 2309-44.

See also the post from the superintendent of the Minneapolis Public Schools where she states, "Minority students do not misbehave more than their white peers; they are disciplined more severely for the same behaviors. For example, a study of North Carolina schools found that discipline gaps exist for various infractions: for dress-code violations, black students were suspended at a rate six times higher than white students; for cellphone use, it was eight times higher; for displays of affection, 10 times higher; and for disruptive behavior, it was double."
