Model-based methods for estimating the population mean in stratified clustered sampling are described. The importance of adjusting the weights is assessed by an approach considering the sampling variation of the adjusted weights and its (variance) components. The resulting estimators are more efficient than the jackknife estimators for a variety…

This study examines the magnitude of the difference between estimates from the 1990-91 Schools and Staffing Survey (SASS) using a Common Core of Data (CCD) definition of a school and a Quality Education Data (QED) definition of a school. The 1990-91 SASS sample design allows for the development of school and administrator estimates using either…

This report describes the methods and procedures used for the 2000 National Postsecondary Student Aid Study (NPSAS:2000). NPSAS:2000 included notable changes from previous NPSAS surveys (conducted in 1987, 1990, 1993, and 1996) in its sample design and collection of data. For example, this study is the first to restrict institutional sampling to…

This profile presents and summarizes available information about the quality of data from the five surveys that comprise the SASS, along with background material on the survey design and procedures for the following: (1) School Survey; (2) School Administrator Survey; (3) Teacher Demand and Shortage Survey; (4) Teacher Survey; and (5) Teacher…

A 1994 report, "Quality Profile for SASS, Aspects of the Quality of Data in the Schools and Staffing Surveys (SASS)," presented and summarized the available information about the quality of the data from the five surveys that made up the SASS in its first two rounds of data collection (1987-1988 and 1990-1991). This report updates the…

Procedures for obtaining student samples for the National Assessment of Educational Progress (NAEP) and deriving survey weights for analysis of survey data are described. Sample designs are economically and operationally feasible, and weighting procedures result in increased precision of estimates as they account for the probabilities of student…

The Integrated Postsecondary Education Data System (IPEDS) of the National Center for Education Statistics collects data from all sections of postsecondary education. For less-than-two-year institutions, the IPEDS collects data on fall enrollment, completions (earned awards and certificates), etc., from all public institutions in that category and…

This report describes the methods and procedures used for the 1996 National Postsecondary Student Aid Study (NPSAS:96). NPSAS:96, which surveyed over 830 postsecondary education institutions and over 34,000 students and parents, included important changes from previous NPSAS studies conducted in 1987, 1990, and 1993 in its sample design and data…

This report presents an investigation by the American College Testing Program (ACT) of an alternative design for the National Assessment of Educational Progress (NAEP). The proposed design greatly simplifies the data collection and analysis procedures needed to produce assessment results and has the potential to produce results that are more…

The 1992-93 National Study of Postsecondary Faculty (NSOPF-93), the second cycle of this study, surveyed institutions and faculty, with a sample of 974 public and private nonproprietary higher education institutions and 31,354 faculty members. The study was designed to provide a national profile of faculty, including their professional…

The effectiveness of multiple matrix sampling was examined in a study of 495 students' attitudes toward a computer education program. A post hoc analysis of variance was used, with the class as the unit of analysis. The Computer Attitude Scale, a 30-item rating scale, was used to measure attitudes toward learning about and working with computers.…

Tools used in scaling proficiency scores from the Second International Assessment of Educational Progress (IAEP) are described. The second IAEP study, conducted in 1991, was an international comparative study of the mathematics and science skills of samples of 9- and 13-year-old students from 20 countries. This paper focuses on part of the second…
