An Empirical Comparison of Five Linear Equating Methods for the NEAT Design

Measurement, 2009
In this study, a data base containing the responses of 40,000 candidates to 90 multiple-choice questions was used to mimic data sets for 50-item tests under the nonequivalent groups with anchor test (NEAT) design. Using these smaller data sets, we evaluated the performance of five linear equating methods for the NEAT design with five levels of group ...

A New Approach to Comparing Several Equating Methods in the Context of the NEAT Design

Journal of Educational Measurement, 2010
The nonequivalent groups with anchor test (NEAT) design involves missing data that are missing by design. Three equating methods that can be used with a NEAT design are the frequency estimation equipercentile equating method, the chain equipercentile equating method, and the item‐response‐theory observed‐score‐equating method.

TESTING THE UNTESTABLE ASSUMPTIONS OF THE CHAIN AND POSTSTRATIFICATION EQUATING METHODS FOR THE NEAT DESIGN

ETS Research Report Series, 2006
ABSTRACTThis paper focuses on the Non‐Equivalent Groups with Anchor Test (NEAT) design for test equating and on two classes of observed—score equating (OSE) methods—chain equating (CE) and poststratification equating (PSE). These two classes of methods reflect two distinctly different ways of using the information provided by the anchor test for ...

Comparison of Outlier Detection Methods in NEAT Design

2021
In equating practice, the existence of outliers in the anchor items can deteriorate the equating accuracy and threaten the validity of test scores. This study used simulation to compare the performance of three outlier detection methods when conducting equating: the t-test method, the logit difference method, and the robust z statistic.

The Missing Data Assumptions of the Neat Design and their Implications for Test Equating

Psychometrika, 2010
The Non-Equivalent groups with Anchor Test (NEAT) design involves missingdata that are missing by design. Three nonlinear observed score equating methods used with a NEAT design are the frequency estimation equipercentile equating (FEEE), the chain equipercentile equating (CEE), and the item-response-theory observed-score-equating (IRT OSE).

EQUATING OF SUBSCORES AND WEIGHTED AVERAGES UNDER THE NEAT DESIGN

ETS Research Report Series, 2011
ABSTRACTRecently, the literature has seen increasing interest in subscores for their potential diagnostic values; for example, one study suggested the report of weighted averages of a subscore and the total score, whereas others showed, for various operational and simulated data sets, that weighted averages, as compared to subscores, lead to more ...
