摘要

In 2003 the National Center for Education Statistics (NCES) conducted the National Assessment of Adult Literacy (NAAL) to measure the nations English literacy skills, following up on the National Adult Literacy Survey (NALS), conducted in 1992. The 2003 NAAL interviewed over 18,500 adults (age 16 and older) across the country in private households. The overall sample comprised a core national sample supplemented by samples in six states that participated in the State Assessment of Adult Literacy (SAAL). The SAAL was designed to provide estimates of adult literacy levels for each of the participating states. In a similar fashion, the 1992 NALS interviewed over 24,000 adults in private households, consisting of a core national sample supplemented by samples in the 11 states that participated in the State Adult Literacy Survey (SALS). The two surveys were designed to provide standard survey estimates direct estimates of literacy proficiency with adequate levels of precision for the target population for the nation as a whole, for major population subgroups (e.g., subgroups defined by region, level of educational attainment, and race/ethnicity) within the nation, and also for those states participating in the SAAL or SALS. However, based on the survey data alone, neither survey was designed to provide policymakers and educators estimates of the percentages of adults at the lowest literacy level at the state or county. Thus, NCES undertook a project to produce estimates of adults at the lowest literacy level for individual states and counties using statistical modeling approaches. These model-dependent estimates are called indirect estimates to distinguish them from standard or direct estimates that do not depend on the validity of a statistical model. The county and state indirect estimates were produced using small area estimation techniques that rely on survey data as well as data from other sources such as the decennial censuses for each of the two survey years. This report describes the statistical methodology used to produce the model-dependent indirect estimates of the percentages of adults at the lowest literacy level for individual states and counties for 1992 and 2003.
