This document is the users' guide for Version 1.0 of the Public-Use data tapes compiled by the National Assessment of Educational Progress (NAEP), 1985-86. The Public-Use tapes are produced to allow outside researchers access to the NAEP data. The tapes accompanying this guide, one for grade 3/age 9, one for grade 7/age 13, and one for grade…

The National Assessment of Educational Progress (NAEP) has completed two assessments of mathematics, the first conducted in 1972-73 and the second during 1977-78. Each assessment surveyed the mathematics achievement of American 9-, 13-, and 17-year-olds, using a deeply stratified, multi-stage probability sample design. This report documents…

This document describes the breadth of the research being conducted in 2008 by the Research and Development Division at Educational Testing Service (ETS). The research described falls into three large categories: (1) Research supported by the ETS research allocation; (2) Research funded by testing programs at ETS; and (3) Research funded by…

The current study is a comparison of the characteristics of the candidates from the Grossmont Union High School District who took the March 1976 administration of the California High School Proficiency Examination, with special attention to the differences between those candidates who passed the examination and those who did not .

A standard-setting procedure was developed for the Georgia Teacher Certification Testing Program as tests in 30 teaching fields were revised. A list of important characteristics of a standard-setting procedure was derived, drawing on the work of R. A. Berk (1986). The best method was found to be a highly formalized judgmental, empirical Angoff…

The report presents local norms and tables derived from scores of the third administration of the Metropolitan Achievement Test Battery to pupils in grades 2, 4, and 6 in the Northwest Territories during November and December of 1968, and similar data from testing in 1966 and 1967. The student population in the schools consisted of 3 broad ethnic…

Latent trait model calibration procedures were used on data obtained from a group testing program. The one-parameter model of Wright and Panchapakesan and the three-parameter logistic model of Wingersky, Wood, and Lord were selected for comparison. These models and their corresponding estimation procedures were compared, using actual and simulated…
