A latent variable modeling method for studying measurement invariance when evaluating latent constructs with multiple binary or binary scored items with no guessing is outlined. The approach extends the continuous indicator procedure described by Raykov and colleagues, utilizes similarly the false discovery rate approach to multiple testing, and…

In this study, we propose that the unique needs and characteristics of linguistic minorities should be considered throughout the test development process. Unlike most measurement invariance investigations in the assessment of linguistic minorities, which typically are conducted after test administration, we propose strategies that focus on the…

In a typical differential item functioning (DIF) analysis, a significance test is conducted for each item. As a test consists of multiple items, such multiple testing may increase the possibility of making a Type I error at least once. The goal of this study was to investigate how to control a Type I error rate and power using adjustment…

Multiple-indicators multiple-causes (MIMIC) modeling is often used to test a latent group mean difference while assuming the equivalence of factor loadings and intercepts over groups. However, this study demonstrated that MIMIC was insensitive to the presence of factor loading noninvariance, which implies that factor loading invariance should be…

Partly in response to increased testing and accountability, states and districts have been raising the minimum school entry age, but existing studies show mixed results regarding the effects of entry age. These studies may be severely biased because they violate the monotonicity assumption needed for LATE. We propose an instrument not subject to…

Previous arguments against the use of Analysis of Variance (ANOVA) to determine test bias are extended. Explains why ANOVA may obscure test bias when it exists and also create a false impression of bias when it does not exist. (RB)

The purpose of this investigation was to establish the effects of repeaters on test equating. Since consideration was not given to repeaters in test equating, such as in the derivation of equations by Angoff (1971), the hypothetical effect needed to be established. A case study was examined which showed results on a test as expected; overall mean…

The GRE Board established the Research Program to investigate ways to improve the GRE and its overall operation. Approximately 30 projects have been undertaken and funded by the GRE Board; perhaps a third of these have been completed. These projects can be divided into three groups: (1) those dealing with product or process or marketing…

Responses on both the state and trait scales of the State-Trait Anxiety (STAI) Inventory were examined under two conditions. The first condition presented a simulated real-life situation containing competitive and evaluative cues without directly suggesting faking and asked subjects to complete the STAI. After an intervening task, the STAI was…

In order to screen out items which may be biased against some ethnic group prior to the final selection of items in test construction, a statistical technique for assessing item bias was developed. Based on a theoretical formulation of R. B. Darlington, the method compares the performance of individuals who belong to different ethnic groups, but…

Statistical, legal and moral problems involved in following the EEOC guidelines are described. The guidelines require separate data for minority and non-minority groups with differential cut off scores for aptitude tests which have a racial bias. Problems reviewed include: identification of racial bias in tests is difficult; giving one race an…
