Large-scale educational and literacy surveys, such as the National Assessment of Educational Progress (NAEP), the National Education Longitudinal Survey (NELS), and the National Adult Literacy Survey (NALS), often provide sufficient information about their target populations and certain well-represented subpopulations, but they cannot be used directly for inferences about small areas, such as states, counties, or other geographical units. National surveys do contain some information about small areas, but such information may be difficult to extract and, on its own, may be insufficient for inferences with a desired level of confidence.
