A study was made of the prose, document, and quantitative literacy skills of adults in the United States by their highest level of educational attainment. In addition, the study examined the literacy skills of recent General Educational Development (GED) graduates. The data used in the study came from the 1992 National Adult Literacy Survey (NALS), conducted by the National Center for Education Statistics, and the 1993 GED-NALS Comparison Study. Highlights of the findings include the following: (1) adults with a college education demonstrated higher levels of literacy skills than their counterparts with little or no college education; more than 70 percent of college graduates demonstrated moderate to high levels of literacy skills; (2) adults whose highest educational attainment was a GED credential or a high school diploma had the same average literacy skills, and about one-half of these adults demonstrated moderate to high levels of literacy skills; (3) among both college-educated adults and adults without college degrees, whites demonstrated higher average literacy skills than their African American and Hispanic counterparts in all three measures of literacy; and (4) among recent GED graduates, about 65 percent demonstrated moderate to high levels of literacy skills in prose and document tasks and nearly 57 percent performed at those levels in quantitative literacy.
