Methods to handle ordered-categorical indicators in latent variable interactions have been developed, yet they have not been widely applied. This article compares the performance of two popular latent variable interaction modeling approaches in handling ordered-categorical indicators: unconstrained product indicator (UPI) and latent moderated…

Prospective longitudinal data collection is an important way for researchers and evaluators to assess change. In school-based settings, for low-risk and/or likely-beneficial interventions or surveys, data quality and ethical standards are both arguably stronger when using a waiver of parental consent--but doing so often requires the use of…

This study defines subpopulation item parameter drift (SIPD) as a change in item parameters over time that is dependent on subpopulations of examinees, and hypothesizes that the presence of SIPD in anchor items is associated with bias and/or lack of invariance in three psychometric outcomes. Results show that SIPD in anchor items is associated…

This exploratory study investigated potential sources of setting accommodation resulting in differential item functioning (DIF) on math and reading assessments for examinees with varied learning characteristics. The examinees were those who participated in large-scale assessments and were tested in either standardized or accommodated testing…

The purpose of this study is to describe a new approach for evaluating the judgments of standard-setting panelists within the context of the bookmark procedure. The bookmark procedure is widely used for setting performance standards on high-stakes assessments. A many-faceted Rasch (MFR) model is proposed for evaluating the bookmark judgments of…

This article introduces the Measurement Skills Assessment (MeSA), which was designed to evaluate the mastery of measurement in elementary school students. The primary objectives for the MeSA include covering a broad range of measurement concepts, distinguishing between major subtypes of measurement, and constructing a continuum of items varying in…

The Multisource Assessment of Social Competence Scale was developed, based on the School Social Behavior Scale and examined to test the factor pattern and the consistency of the ratings of self, peers, teachers, and parents. The findings of the confirmatory factor analysis supported a four-factor solution consistent with two main dimensions…
