The purpose of this study was to evaluate the combined effects of reduced equating sample size and shortened anchor test length on item response theory (IRT)-based linking and equating results. Data from two independent operational forms of a large-scale testing program were used to establish the baseline results for evaluating the results from…

In this technical report, we present the results of a reliability study of the third-grade multiple choice reading comprehension measures available on the easyCBM learning system conducted in the spring of 2011. Analyses include split-half reliability, alternate form reliability, person and item reliability as derived from Rasch analysis,…

In this technical report, we present the results of a reliability study of the fifth-grade multiple choice reading comprehension measures available on the easyCBM learning system conducted in the spring of 2011. Analyses include split-half reliability, alternate form reliability, person and item reliability as derived from Rasch analysis,…

In this technical report, we present the results of a reliability study of the fourth-grade multiple choice reading comprehension measures available on the easyCBM learning system conducted in the spring of 2011. Analyses include split-half reliability, alternate form reliability, person and item reliability as derived from Rasch analysis,…

In this study, differential item functioning (DIF) methods utilizing 14 different matching variables were applied to assess DIF in the constructed-response (CR) items from 6 forms of 3 mixed-format tests. Results suggested that the methods might produce distinct patterns of DIF results for different tests and testing programs, in that the DIF…

In this technical report, we present the results of a reliability study of the sixth-grade multiple choice reading comprehension measures available on the easyCBM learning system conducted in the spring of 2011. Analyses include split-half reliability, alternate form reliability, person and item reliability as derived from Rasch analysis,…

Test items undergo multiple iterations of review before states and vendors deem them acceptable to be placed in a live statewide assessment. This article reviews three approaches that can add validity evidence to states' item review processes. The first process is a structured sensitivity review process that focuses on universal design…

This document describes the breadth of the research that the ETS (Educational Testing Service) Research & Development division is conducting in 2010. This portfolio will be updated in early 2011 to reflect changes to existing projects and new projects that were added after this document was completed. The research described in this portfolio falls…

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…

This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). This report describes the processes used for deciding what should be measured, when, and how. Work of the SMSG Panel on Tests for collecting tests items, conceptualizing scales, pilot testing, and analyzing pilot test data is reviewed. The…

This Brief builds on the work of the National Association of State Boards of Education 1997 Study Group on State Assessment Systems by examining one of the state board actions that is most likely to capture the publics attention: setting cut scores on state assessments. This process involves a large measure of human judgment and politics and a…

This study addressed statistical techniques that might ameliorate some of the sampling problems currently facing states with small populations participating in State National Assessment of Educational Progress (NAEP) assessments. The study explored how the application of finite population correction factors to the between-school component of…

The accounting department at the University of Arizona, faced with numerous sections of introductory accounting, full classrooms, testing periods spread over two days, and a shortage of clerical help, evolved this testing program for the course in introductory accounting. Two objective multiple choice tests are constructed which sample different…

This bulletin describes two phases of an experiment in examining science, one in 1963, and the second in 1964. The first phase of the experiment explored two forms of assessment: a Scientific Thinking paper; and a Practical paper. In the second phase two further factors were introduced: a Facts and Principles paper; and an Assessment of course…

The two phases in the development and tryout of a Guidance Counselor Test to be added to the National Teacher Examinations Program are discussed. In Phase One, a 150-item written test and a 50-item written test based on taped stimulus material were produced. Each test consisted of five-choice multiple-choice questions. In Phase Two, the tests were…
